Happy Valentine's Day!

Roses are red

Violets are blue

Watch out for gummy bears

and jaw breakers, too

Valentine's Day will be here in nearly a week! Whether you're spending the day with a loved one, having a fun party with your friends, or simply relaxing before the work week, you are sure to encounter a few yummy desserts and candies. While everyone enjoys something sweet once and again, it is always good to consider how they impact your health. Here are a few tips for keeping your mouth in good shape during Valentine's Day.

1. Not all candy is created equal. 

• Some candies are worse than others. Tough candy that stays in your mouth for a prolonged period of time such a jawbreakers and suckers can lead to cavities or even chipped teeth. The best option for this type of sweet is to opt for a sugar-free alternative. This way, you are satisfying your sweet tooth without the risk of tooth decay. 
• Also, be on the lookout for chewy candies like gummy bears, taffy, and caramel. Even though these treats are sure to satisfy, they are stubborn and tend to stick to your teeth. This makes these chewy confections more difficult to break down with saliva.  

2. Select your beverages with care.

• While they might be packed full of vitamin C, it is best to avoid drinks that have too much citrus like orange grapefruit juice. The acid from these beverages can erode away your enamel and weaken your teeth.  
• If you are wanting a soda with your meal, keep in mind that its carbonation and sugar can also damage your enamel. Sugar-free sodas are a better alternative, but water is always the best option. 
• Even though most people enjoy a nice cup of coffee in the morning, the caffeine coupled with its dark color can dry out your mouth and stain your teeth. Consume it in moderation and try drinking with a straw to avoid some of those stains. 
• If you find yourself wanting to a cold drink, try refrigerating it instead of adding ice. Chewing ice can lead to dental emergencies and isn't the safest way to go. 

3. Look out for your pearly whites.   

The best way to prevent cavities and other dental health diseases is to take care of your teeth. Remember to brush your teeth twice per day and floss once. If you decide to eat or drink anything too acidic, try waiting at least thirty minutes before brushing your teeth.

Dental Insurance Coverage

Your employer, management, or union has purchased dental insurance coverage from a selection of plans offered by an insurance company or broker. Each insurance company offers many different plans. 

What is covered?
The type of dental benefits that are covered relate to the dollar amount spent on the benefit package. Generally, the more money spent on a plan, the more services are covered. Most dental insurance covers only 50% to 80% of the cost of the treatment. Major services (crowns, bridges, etc.), which are the most expensive dental procedures, are usually only covered at a 50% rate. For example, some dental benefit packages will not cover the fees for porcelain (tooth-colored material) crowns on teeth that are not visible when you talk or smile; they will only pay for a metal crown. Under this type of plan, you must pay the full amount of the cost of the porcelain on those teeth. According to insurance companies, fillings in front teeth have both functional use and cosmetic components. They will pay for the functional part but not the full amount for the cosmetic restorations.

Who is responsible for payment?
The fees charged for dental treatment reflect the many different parts of a particular procedure or procedures. Treatment for your particular needs may or may not fall within the limits set by your particular dental plan. Many dental procedures may not even be listed in your insurance's procedure/payment schedule. If your dental procedure falls into this category, you may not receive any insurance reimbursement for that procedure. You are ultimately responsible for paying the entire fee for an accepted dental treatment, regardless of your insurance coverage.

Choosing Treatment Options
Our goal through your examination, diagnosis, and treatment phases is to provide you with the best possible oral health. We do not allow the insurance company to tell us how to treat you. We recommend to you those treatments that we believe you need and we will discuss alternative plans with you. Whether or not the recommended treatment is a covered dental benefit is between you and your employer and the insurance carrier.

Submitting the Claim
We are happy to help you receive the maximum benefits you are allowed from your dental coverage. In order for us to submit your insurance claim, we will need an insurance form with your portion completed and signed. We deal with dental insurance companies on a daily basis; therefore, we have a great deal of experience submitting these claims to insurance carriers. We take great care in submitting claims properly the first time. 

There are three things we cannot do: 
1) Alter the date of treatment; 
2) Submit a claim for more than the actual fee; 
3) Submit a claim for procedures that have not been performed. 

Because it is not at all uncommon for the insurance carriers to make a mistake, we would prefer to submit the claims ourselves, and then verify proper payment. Insurance carriers may respond to requests for payment of preauthorized treatment in as little as a week or as long as 45 days. Please be patient; we have no control over the post office or the speed with which the insurance carrier processes your claim.

Our office cannot negotiate with your insurance company for reimbursement of dental expenses. Only the purchaser of the plan (your employer) can negotiate better coverage. If you would like better or more coverage, you will need to talk with your plan purchaser about the features you want in your dental plan.

If you have any questions about your dental insurance coverage, please feel free to ask us. 

Remineralization Device Could Soon Come to Market

A new device being developed by dental researchers at King's College London could soon bring to market an electronic tool that would encourage teeth to remineralize. 

Demineralization and remineralization have a crucial impact on the hardness and strength of tooth enamel.

What is demineralization?
Poor hygiene, bad brushing techniques, as well an inappropriate diet can lead to tooth decay due to changed acid levels in the oral cavity. Demineralization occurs at a low pH (acidic) when the oral environment is UNDERsaturated with mineral ions. Acids demineralize the tooth structure by dissolving calcium, phosphorus, etc. The enamel is dissolved by these organic acids (lactic and acetic acids) that are produced by the cellular action of plaque bacteria in the presence of dietary carbohydrates. This enamel erosion leads to dental cavities. 

Demineralized surfaces are porous and adherent, thus becoming favorable to bacteria growth that causes dental cavities and decay. In other words, enamel demineralization equals the beginning of cavity formation. Often, as a result of smoothness reduction, the tooth surface may suffer from superficial pigmentation, which can be visually unpleasant and impossible to remove with the toothbrush. 

Demineralized teeth are very sensitive to diverse stimuli: sensitive to hot and cold foods and drinks, as well as sensitive to the touch; brushing can be uncomfortable, even painful, and the patient can be tempted to skip brushing or cut it short, which is usually fatal for his or her teeth. When demineralized hypersensitive teeth are not properly cleaned, severe dental cavities affect the entire dental structure. Treatment becomes difficult. Patients need to understand that this condition appears as a result of an infection that can easily get out of control if hygiene is neglected.

What is remineralization?
Remineralization allows the loss of calcium, phosphate, and fluoride ions to be replaced. 

How do dentists fix cavities now?

With 2.3 billion affected annually, dental caries is one of the most common preventable diseases globally. Tooth decay normally develops in several stages, starting as a microscopic defect where minerals leach out of tooth. Dentists normally treat established caries in a tooth by drilling to remove the decay and filling the tooth with a material such as amalgam or composite resin. 

What can this tool do?
Reminova Ltd, a company that emerged from King's College London Dental Innovation and Translation Centre, takes a different approach - one that rebuilds the tooth and heals it without the need for drills, needles, or amalgam. By accelerating the natural process by which calcium and phosphate minerals re-enter the tooth to repair a defect, the device boosts the tooth's natural repair process.

How would the tool work?

Electric currents already used to check pulp/nerve of a tooth

The two-step method developed by Reminova first prepares the damaged part of the enamel outer layer of the tooth and then uses a tiny electric current to "push" minerals into the tooth to repair the damaged site. The defect is remineralized in a painless process that requires no drills, no injections, and no filling materials. Electric currents are already used by dentists to check the pulp or nerve of a tooth; the new device uses a far smaller current than that currently used on patients and cannot be felt by the patient. The technique, known as Electrically Accelerated and Enhanced Remineralization (EAER), could be brought to market within 3 years.

What is the company?
Reminova Ltd will be based in Perth, Scotland, to benefit from the strong life sciences and dentistry base. It will commercialize the work of Professor Nigel Pitts and Dr. Chris Longbottom, based in the Dental Institute at King's College London. With a combined 80 years' experience in dentistry, they have previously brought dental devices to market to detect tooth decay. The company, formed in collaboration with Innova Partnerships, is currently seeking private investment to develop their remineralization device. 

Who are the designers?
Kit Malthouse, chair of MedCity and London's deputy mayor for business and enterprise, commented, "It's brilliant to see the really creative research taking place at King's making its way out of the lab so quickly and being turned into a new device that has the potential to make a real difference to the dental health and patient experience of people with tooth decay."

Prophylaxis

There is nothing more important to your dental health than maintaining a clean mouth. Prevention or absence of infection optimizes our general health. A clean mouth will be disease-, infection-, and trouble-free. A clean mouth will not be predisposed to developing either decay or periodontal (gum) disease. One of our very important functions in dentistry is to teach you how to properly maintain your teeth and gums, and to regularly remove anything that you are unable to remove yourself.

The theory and practice of preventive dentistry have undergone revolutionary changes in recent years. We now know that the preventive needs of every individual differ. The adage of "see you dentist regularly; get your teeth cleaned twice a year" has changed too.

What Is Prophylaxis?
Oral prophylaxis is a simple dental procedure by which your dentist or hygienist will clean your teeth using hand instruments or ultrasonic scaler. No matter how good you are at cleaning your teeth, there is always plaque left between your teeth and at the gum line. As time advances and cleaning is neglected, the early stage soft plaque will change into hard tartar (calculus). This plaque and calculus gives rise to periodontitis and gingivitis.

How Oral Prophylaxis Is Done
1. Sit back and relax on the dental chair while your dentist evaluates your medical history
2. Dentist will examine your mouth and look for signs of periodontal pockets and gum infections
3. An ultrasonic scaler will be used to clean your teeth. The scaler is a hand-held device with a hand piece and a pointy tip. It ejects pressurized water and the tip vibrates in order to remove the plaque and calculus from the teeth surface
4. Hand instruments are used to clean tricky spots and difficult to reach areas
5. If you have any cavities or gum problems, you will be notified
6. In the end, a prophylaxis paste will be used for polishing the tooth surface. A miniature rubber cup is fitted over a hand piece and small amount of prophy paste will be applied on the cup and your teeth will be polished 

How Often Should You Schedule Cleanings?
The recare and examination interval that we have recommended for you is designed for your unique situation. And it, too, can change. The interval between regular prophylaxis (cleaning) appointments that is established for you is a function of many things.
These include:

• general health

• dexterity and hand/eye coordination

• age

• diet

• stress levels

• oral habits

• position and alignment of the teeth

• number, type, size, and location of restorations

• restorative materials used

• periodontal history

• location of bone and periodontal tissues

Simply stated, the more complex your dental situation and the more your tooth position and alignment deviate from the normal, the harder you will find it to keep your teeth clean and your gums healthy.

Recent studies have identified many of the microorganisms that cause gum disease and decay. They can be controlled with your help and with ours. These studies also show that a "cleaning" every 6 months may not be adequate for some patients. In order to prevent destructive oral disease, prophylaxis appointments in intervals of anywhere from 2 months to a year may be recommended. Periodontal (gum) disease can happen anywhere in your mouth at any time.

You don't have to let it happen to you! We are here to be your guide to good health.

If you have any questions about your oral care maintenance intervals, please feel free to call our office at 512-250-5012.

Scaling and Root Planing

What is scaling?
Scaling is a periodontal dental procedure in which plaque and calculus are removed from the tooth both above (supragingival) and below (subgingival) the gum (gingiva). 

What is root planing?
Root planing is a procedure in which diseased or altered portions of the root surface, the cementum, and dentin are removed and the resulting new surface is made smooth and clean. The more altered and damaged the root surface has been from calculus (tartar) accumulation, the more the need for root planing.

Why is it necessary?
The purpose of scaling and root planing is to remove all debris from the teeth. Any item that can cause inflammation of the gum tissue must be eliminated. The root surface must be made as smooth as possible. Irregularities in the root surface can contribute to gum inflammation. Irregularities are sites for bacteria and plaque buildup. The bacteria and the toxins they produce in the plaque are held against the tooth by the calculus. In this way, plaque and calculus on the teeth have been positively linked to gum disease.

What is the procedure like?
Depending on the severity of your particular periodontal problem, scaling and root planing may be the definitive treatment and no further procedures will be required. In many cases scaling and root planing are only a necessary part of the overall therapy. It is a demanding procedure. It requires much more time than the familiar adult prophylaxis (cleaning). It is usually done in multiple appointments, treating a quarter, half mouth, or your full mouth at each appointment. In this office we find that most patients are most comfortable if the area to be treated during the root planing procedure is anesthetized with a local anesthetic.

Recare
The scaling and root planing may have to be repeated in the future. It is customary to place the patient on a 3- to 4-month hygiene recare schedule. Scientific evidence clearly shows that for individuals who have demonstrated a predisposition to periodontal disease, an interval of 6 months is too long. We will determine the appropriate interval for you. As your situation changes, there may be changes in the length of these intervals as well.

What happens after treatment?
Other than the teeth being somewhat sensitive after the scaling and root planing procedure, there is little postoperative discomfort. The sensitivity will diminish with time. If you have been diagnosed as having severe periodontal infection, the sensitivity may remain for quite some time and further procedures may be needed to eliminate sensitivity. Although many procedures in dentistry can be considered elective, we consider scaling and root planing to be a necessity for your dental health.

Post-procedure Tips:

• If therapeutic prophylaxis has been completed because your gingival (gum) tissue showed signs of infection and inflammation, and if you had significant calculus (tartar) buildup:

• You may notice that your teeth feel different where the calculus was removed. The soft tissues may be sensitive or sore for approximately one day as they begin to heal. You may find that taking an over-the-counter pain reliever (aspirin, ibuprofen, etc.) will help during this 24-hour period. You may also rinse your mouth every few hours with warm salt water. Make sure that you brush and floss your teeth during this time period as you have been instructed. be gentle, because the brushed areas may be sore, but be thorough! You do not want to have the periodontal infection begin again.
• If scaling and root planing, or other more involved periodontal procedures has been completed:

• You can expected your gingival (gum) tissues to be quite sore. This is normal when the gum tissues have been infected and inflamed for some time. The more severely they have been affected, the more discomfort you can expect. This soreness should go away very quickly. You may rinse with warm salt water every few hours until the soreness is gone.
• If scaling and root planing has been completed:

• You may also notice that the teeth have become sensitive to temperature changes after the scaling and root planing. This sensation frequently occurs when the surfaces of the roots of your teeth have been cleaned. Removal of the debris covering the roots and attached to the roots leaves the roots open to temperature stimulus. If the problem persists, please let us know.
• When you examine your gums closely in a mirror, you will also observe that the color, texture, and position of your periodontal tissues will undergo a change as the healing takes place. The swollen, reddened gum tissue will shrink, become more firm, and return to a healthy pink color. Watch for these welcome signs of improvement and be encouraged by the healing process.
• Please do not forget to brush, floss, and use other periodontal cleaning aids as you have been taught. It is important that you begin establishing proper oral self-care habits immediately. If you find that the recently treated areas are sensitive to the brushing and flossing, be gentle - but be thorough! With proper technique you cannot damage the teeth or gingival tissues.
• Brush after ever meal with a fluoride-containing toothpaste. Rinse with a fluoride-containing mouthrinse once each day.

Preventing Recurrence
Once scaling and root planing has been completed, it is most important for you to practice the brushing and flossing techniques in which you will be instructed. If we have recommended any additional periodontal aids, you must use them, too. Your cooperation is vital if the procedures are to be successful. To remain disease-free, you will need to remain constant in your oral self-care regimen.

If you have any questions about scaling and root planing, please feel free schedule a comprehensive dental exam with our office at 512-250-5012.

Does Oil Pulling Work?

Starting the day off at the beach with your skin smelling of tropical-scented sunscreen can be one of life's greatest pleasures. Smelling coconut oil as you swish it around in your mouth before work -- well, that's another story. 

What is Oil Pulling?

Oil pulling, or placing oil in the mouth to kill harmful bacteria, seems to have caught on recently. It's a controversial practice that takes dedication and time, though fortunately not the 10 or 20 minutes of marathon swishing some sources suggest. Oil pulling, an ancient Ayurvedic folk practice, dates back 3,000 to 5,000 years to traditional Indian medical remedies. Advocates claim swishing any type of oil in your mouth every day will whiten your teeth, reduce bacteria, strengthen your gums and jaw, improve your skin, clear your sinuses, prevent ​bad breath and even protect against heart disease and Alzheimer’s disease. 

Two sessions of four minutes, as recommended by Dr. Amala Guha, assistant professor of immunology and medicine at the University of Connecticut Health Center and the founding president of The International Society for Ayurveda and Health, were sufficient for my first attempt at oil pulling. The taste itself isn't so bad on the surface, but putting chunky coconut oil in your mouth before being fully awake can trigger a gag reflex.

"People are saying that their breath is better, their gums don’t bleed anymore and their teeth look a little whiter," says Jeffrey Dalin​, a dentist based in St. Louis. "I haven’t had the guts to do it, but I think it’s something at least worth looking into." 

What does research say?

But what's the scope (and scoop) on this mouth rinse practice? Does it work?

"It's not given proper credit," said Guha, who was trained in Ayurveda, a traditional form of medicine that relies on natural healing, in India. She explains that using liquids in the mouth for health purposes is mentioned in two ancient Indian Ayurvedic texts (one written in 800 B.C. and the other in 700 B.C.), and the practice is part of one of the oldest health systems in the world.

Oil pulling for oral hygiene is common. But before you go racing out to the store for oil, the American Dental Association cautions that because of a lack of evidence, they do not recommend oil pulling as a replacement for standard oral health care such as flossing and teeth brushing.

The texts also claim that about 30 systemic diseases, including headaches and diabetes, can be cured. Yet there is a lack of knowledge on the science and side effects behind the practice, according to Guha.

A small study published in 2009 involving sesame oil and 20 adolescent boys with plaque-induced gingivitis found that oil pulling reduced plaque and the bacterium Streptococcus mutans. This bacterium is cited as being a major cause of tooth decay and overgrowth of bacteria in mouth can also lead to gum disease.

A larger study published in 2013, also using sesame oil, found similar results, summarizing that oil pulling had a significant effect on plaque and gingivitis.

For coconut oil users, lauric acid found in the oil can be a benefit. It is known for its antimicrobial properties, such as the ability to fight off viruses, bacteria and yeasts.

Another study from 2011 says, "Oil pulling therapy has been equally effective like chlorhexidine [mouthwash] on halitosis and organisms."

How it works

Guha says there are two oil pulling techniques: kavala and gandusa.

Kavala: fill your mouth with liquid and hold it there for a couple of minutes before swirling it around the mouth and spitting it out. The process shouldn't exceed more than three or four minutes; it's repeated at least two or three times.

Gandusa: the technique of holding the liquid still in the mouth for three to five minutes. The liquid is then spit out and the process is repeated.

In Ayurveda, many different liquids can be used depending on the condition being treated and the physiology of the person. Milk, honey and hot water containing herbs are just some of the other mediums, explains Guha.

For daily oral hygiene, she recommends using coconut or sesame oil, which she says have mild abrasive powers and more healing benefits than other oils (and are less harmful).

Where to dispose the oil?

Jennifer Beckinsale, who tried oil pulling for 10 days, spit hers into a disposable cup and threw it away, but didn't like how wasteful that felt. Still, she says she would try oil pulling again. Remember, your sink is out, because the oil may harden and clog your pipes.

When to expect results?

Results can be expected in a few months with benefits such as reduced plaque, cavity prevention and stronger gums for individuals who already have a healthy mouth. For the person with plaque buildup, we recommend a teeth cleaning first for faster results.

How it doesn't work

Mark Wolff, professor and chair at the New York University College of Dentistry, expresses skepticism about oil pulling's effects on oral health. "I am not sure there is any harm, but I have never seen it have any positive effect on my patients who have been using oil pulling or in clinical research that has been published."

Limited research, mostly dating back to 2008 and 2009, suggests oil pulling – particularly with coconut oil – can stop plaque from forming. But evidence is lacking, and experts caution that you shouldn’t expect any greater benefits. "There’s absolutely no data whatsoever that shows diabetes can be treated or prevented, or that heart disease can be," says Lyla Blake-Gumbs, a physician with the Cleveland Clinic’s Center for Integrative Medicine. "It’s not a new practice – it’s been done thousands of years – but there were no real records kept​. So I can’t go to any objective, well-run clinical trials to look into the other claims." 

There is also little research available on the effectiveness of these treatments to cure other diseases.

Negative Side Effects

Guha warns that there can be negative side effects if improper technique is used, including dry mouth, excessive thirst, muscular stiffness, exhaustion and loss of sensation or taste in the mouth. Oil pulling likely won’t cause any adverse effects – so long as you don’t swallow the oil. Doing so could cause diarrhea or an upset stomach, Blake-Gumbs says. And the swooshing itself isn’t going to taste good. Oil, be it olive, sesame or coconut, is often difficult to tolerate – and some types are solid at room temperature, until they begin to melt in your mouth. "I had one patient tell me she did it with sesame oil first, and she couldn’t hold it in her mouth because it was too strong a flavor," Blake-Gumbs says. "Then she tried olive oil, and that was more agreeable to her."

Are You Interested?

Individuals who are interested in trying kavala or gandusa to treat health conditions need to review all credentials of Ayruvedic practitioners before starting any treatment. Guha says that there are very few trained professionals in the United States as none of the Ayurveda schools here are accredited; only schools in India provide the proper certifications.

Bottom line? 

Oil pulling is relatively simple and inexpensive – coconut oil runs around $10 ​or less​ ​​​​– and it’s not invasive. But there’s still no solid evidence that it actually works, and experts agree that if you’re concerned about your teeth, it’s best to brush at least twice a day for two minutes each time.

If you're just looking for a natural way to boost your oral health, you can oil away without supervision and get about the same benefits as commercial mouthwash.

Just don't forget to floss.

Dentin Decay

Detect decay by inspecting the color and hardness
Usually, dental decay is fairly easy to detect. When a cavity is just beginning, it is typically identified by a brown or white color or a change in the translucency of the enamel of the tooth. The dentist or dental hygienist uses a special dental instrument called an explorer to feel the suspect area and check its hardness. If the area is hard, in other words, if no break in the enamel layer is detected, we feel there is not a cavity present. If, however, the surface feels soft and the explorer "sticks" in the suspect site, we feel a cavity is present.

Fluoride makes our enamel stronger, but dentin decay is harder to detect Because of the widespread use and availability of fluoride in our drinking water, foods, and oral care products, we are seeing a different decay pattern. The appearance is different from the typical pattern of decay and more difficult to detect. As the outer surface of the enamel absorbs fluoride (from toothpaste, for example), the enamel becomes very resistant to demineralization and eventual decay. If there is a small break in the integrity of the enamel, a pit or groove where decay-causing bacteria can live, the bacteria can dissolve the enamel in such a way that the hole in the enamel cannot be detected. Once the decay-causing bacteria reach the underlying dentin, the acids eat away at that substance and quickly make a large cavity - but one that still cannot be easily seen or detected. In this way the enamel becomes undermined. A dentist looking at such a small cavity would think it very easy to restore. However, once the decayed portion of the enamel is removed and the dentin becomes visible, the true extent of the damage becomes obvious. The small cavity becomes a big cavity.

One of the major problems with decay that appears to occur only in the dentin is in the detection. If a radiograph is taken a part of the periodic examination process, we may be able to see dentin decay if it is moderate to extensive. Decay seen on radiographs is typically two to seven times greater in the tooth. Modern high-speed radiographic film and reduced x-ray exposure makes it more difficult to detect early decay on radiographs.

You can prevent decay by using fluoride
The conscientious application of a source of topical fluoride, through either an over-the-counter dentifrice or a prescription fluoride product, and thorough plaque removal are essential. Bonded sealants are also an effective protection against dentin decay. We strongly advice these procedures. Periodic examinations at intervals recommended by the dentist catch decay at the earliest possible time. This is the only way to keep small problems from developing into larger problems.

Smile (Lip) Line

What is the lip line?
How many teeth you show when you smile or speak and how much of each tooth (length) is displayed when you smile broadly, or (at the opposite end of the spectrum) when your lips are at rest, are functions of where your upper lip attaches to your face and how old you are.

3 classifications

There are 3 classifications of "lip line" that dentists use - low, medium, and high. 

A low lip line is one in which very little of your teeth are visible when you talk or smile. Someone with a low lip line will show, at the most, a millimeter or two of the edge of the biting edge of the tooth. 

A medium lip line will allow most of the tooth, up to and including a millimeter or two of the gum tissue, to be visible. 

A person with a high lip line will show all the top front teeth and a significant amount of gum tissue when speaking or smiling.

High Lip Line

Changing your lip line
Dentists (and plastic surgeons) have not been very successful in surgically changing the low, medium, or high lip line. There are some dental "tricks" that can be used in limited situations to reduce the amount of gum display evident with a high smile line. Most of the corrective procedures to improve the esthetics of the situation require significant investments of both time and money. Periodontal (gum) surgery, alone or in conjunction with porcelain veneers or ceramic crowns, is more likely. In extreme cases the only option may be to surgically reposition the entire maxilla (with or without orthodontics). Conversely, the appearance of showing no teeth when talking or smiling is regarded as one associated with advanced aging.

There is another component to how much of your teeth show when your lips are at rest, and it has to do with gravity and time. Your face and lips are composed of soft tissue that is under a constant gravity challenge. Gravity always wins, given enough time. There skin and subskin tissues drop over the years. If, with your lips at rest, you showed about 3 mm of the biting edges of the top two front teeth when you were 20 years old, by the time you are 40, you may show only 2 mm of edge. Someone 50 years of age would show 1 mm, and at 60 years, maybe no tooth is seen when the lips are at rest. The tissues of the human face will drop about 1 mm every 10 years, beginning around age 40. As the facial tissues lose elasticity, they slowly drop. Obviously, some lucky people have better genetics and their faces will stay tighter and the tissue drop will be slower. Correcting the age-related facial tissue drop can be done with plastic surgery - the common face lift.

High, medium. and low lip lines

Genetics or Gravity? 
If you are reading this, then you have either asked questions about your smile and lip line or this issue has been addressed in the broader context of cosmetic dentistry procedures you require. After a thorough examination, we will explain what situation you have and what corrective measures are possible.

Sealants and Fluoride: Benefit to Adult Patients

Dental decay can develop at any time, regardless of a person's age. A change in diet, change in lifestyle, change in oral self-care habits, the use of prescription medications, or a change in systemic health due to the normal aging process can all affect the caries (decay) susceptibility. Few people remain completely free of decay. Proper oral self-care on your part and properly spaced dental hygiene prevention appointments will go a long way to reduce the opportunity to have new decay to begin.

As you age, it is possible that some of your gum tissue will recede, exposing the root surfaces of your teeth. This gum recession can occur from improper brushing (brushing too hard with a hard toothbrush) or as a result of past periodontal problems. The more a tooth and root are exposed, the greater is the surface area you will have to keep clean. Sometimes the teeth with exposed roots are very hard to keep clean. These roots may be sensitive to temperature changes and are often times uncomfortable to brush. Decreased salivary flow (dry mouth) helps to create a breeding ground for bacteria to accumulate on the enamel and especially on the root surface. And root decay usually progresses quite quickly!

Goal of Prevention
Your goal should be to keep the dentist from drilling your teeth. Any reasonable preventive measure that is available should be seriously considered. When the dentist drills, you lose. When the dentist does not drill, you win.

                               
                                                         Dental Sealants

Please see our blog post on sealants. Although sealants are primarily designed for children, adults who have a history of active decay should consider having sealants placed on the posterior (back) teeth where indicated. We will tell you where it is possible to place the sealants. Even if you have not had a cavity for a long time, consider the application of a sealant as an inexpensive insurance policy for your teeth. Perhaps you would never get decay on the unsealed surfaces. But, just as you insure your home against destruction by fire, a sealant insures the tooth surface from decay. Preventive measures may allow you to avoid having your teeth drilled. You win! 

Topical Fluoride
For a similar reason, we advise the use of topical fluoride treatments for adults. The effectiveness of systemic and topical fluoride in preventing decay is well documented. When a cavity first starts, an application of fluoride might (depending on when it is used) reduce or eliminate the need for drilling.

Fluoride Varnish

An alternative to the fluoride treatment we can provide in our office is a daily rinse. If you can rinse with an over-the-counter mouth rinse containing fluoride every night as directed on the rinse label, you do not need the office topical fluoride treatment. If you cannot rinse daily as instructed, you will need the benefit from the strong office-applied topical fluoride treatment. Your oral health will benefit most from small increments of fluoride that are applied daily rather than one larger concentration every 6 months. However, only you know whether you will be faithful in your rinsing routine. When in doubt, let us do it here.

We stress prevention of dental disease above all else. Sealants and topical fluoride treatments are two of the more important preventive dental measures that we believe will significantly enhance your oral health.
