Does Dental Sealant Protection Outweigh Potential Risks?

                    
Brushing your teeth is important, but dental sealants may be the best way to prevent kids from getting cavities.
A recent report from the Centers for Disease Control and Prevention (CDC) has touted the benefits of the relatively simple and inexpensive procedure in children.
Dental sealants are a thin coating that is painted on teeth to protect them from cavities.
This painless procedure can be $30 to $60 per tooth, although some insurance or discount plans can reduce that cost.
“Considering that less than half of children have them, I’d say [the trend of dental sealants] it still is gaining traction,” Ashley Grill, a New York-based dental hygienist, told Healthline. “Dental sealants are safe and effective, and they’ve been safe and effective for over 40 years.”

What the research shows

The CDC report states that dental sealants prevent 80 percent of cavities for two years after application.
They also continue to protect against 50 percent of cavities for up to four years.
The sealants can be retained in the mouth for up to nine years, according to the CDC.
About 43 percent of 6- to 11-year-old children have a dental sealant. Children from low income households were 20 percent less likely to have sealants than children from higher income households.
School-age children without sealants have almost three times more cavities than children with sealants.
Applying sealants in school-based programs to the nearly 7 million children from low income households who don’t have them could save up to $300 million in dental treatment costs, the CDC reported.
Dr. Valerie Barba, a dentist in New Jersey, told Healthline that sealants are the “most conservative” noninvasive treatment in dentistry.
The sealants need to be monitored and maintained during regular care visits to ensure they do not wear away.
They are technically sensitive to where they are placed, so practitioners who do not apply them correctly may not have the best success rates.

The skinny on sealants

Grill noted that children can report lost school time due to tooth decay, as it can interfere with sleep, eating, and other regular activities.
In addition to preventing cavities, sealants can ensure the teeth stay intact.
“Once a tooth is drilled and filled, restored, or extracted, the natural structure is compromised. There is a lifetime cost associated with maintaining the restored tooth or implant,” she noted.
There are some disadvantages or potential problems with sealants, Grill said. They may need to be reapplied if they fall out, chip, or wear away. In replacement, excess material may need to be drilled down or removed with a scaler.
“I understand the environmental exposure concern about synthetic estrogens such as bisphenol A (BPA),” Grill said.

I’ve never observed an adverse reaction to dental sealants, and none have been reported in the literature.

Ashley Grill, dental hygienist
Salivary BPA levels from exposure to BPA peak three hours after a procedure and return to baseline within 24 hours, she said. Grill added that blood serum levels of BPA have not been detected in clinical studies, but more research is needed.
“I’ve never observed an adverse reaction to dental sealants, and none have been reported in the literature,” said Grill, who applies sealants. “People tolerate dental sealants well.”
If parents are concerned about BPA more than the risks of tooth decay, they should note that treating tooth decay can involve a wealth of dental materials that have more chemicals than BPA. Alternative sealant materials exist, though Grill is not sure if they work better than those containing BPA.
Another issue with sealants is that a person’s bite can feel abnormal after application due to the extra layer on the tooth, Dr. J. Kolby Robinson, a board certified pediatric dentist from Oregon, told Healthline. Some of that wears away over time.
“The main problem with dental sealants is lack of awareness,” Grill added.
Most children don’t benefit from prevention because of overregulation and restrictions at all levels on preventive dental care, Grill said.
Some are insurance barriers, such as only covering certain teeth for sealants. There are also rules imposed by state boards that only allow hygienists working with dentists to place sealants, or requiring a dental examination with a dentist before prevention is allowed.
 

Long-term benefits

If the application technique is perfect, dental sealants can last a lifetime. More often than not, though, they do need to be replaced, Grill said.
“As soon as your child is getting new teeth in with grooves called ‘pits and fissures’ like molars and premolars, get them sealed once they are erupted,” she said. This happens at 6, 12, and 18 years of age.
Baby or primary teeth can be sealed, but the child should be old enough to tolerate the painless procedure, which involves being able to hold their mouth open and not move for a few minutes. Usually, treating younger teeth is performed only on those with an increased risk of tooth decay.
“I recommend getting individual advice on when to seal from your dental team. You can seal any vulnerable surfaces, but retention is best in the pits and fissures,” she said.
Adults can also benefit from sealants.
“All people, no matter age can benefit [from sealants], even adults,” Barba said.
With age, our exposure to decay increases, and the protective quality and biochemistry of saliva changes with certain medications over time. That said, adults are also candidates for this treatment.
But if you already have a restoration or implant, then that tooth will not benefit from a sealant, Grill noted.
“Sealants have proven to be safe and effective,” Robinson said. “The benefits outweigh the risks.”

A Beginner's Basics to Braces

How can orthodontics help you?
If your teeth are in poor alignment, you could be facing a functional or cosmetic problem. Orthodontics (braces) can eliminate that problem for you. One of the first things people notice about you is your smile and how your teeth look. You don't have to be a dentist to notice poorly positioned, crooked teeth. In today's culture, crooked teeth are not regarded as attractive or desirable. Most people, when asked, say that they would like to have straight teeth. Straight, white teeth are the cosmetic dental improvements patients most request.

Braces may also be suggested to correct a specific dental problem that only affects one or several teeth. This is not a cosmetic tooth repositioning, but rather a functional tooth movement. Occasionally, in order to properly finish an orthodontic case, the orthodontist may ask the dentist to adjust the enamel of some teeth or bond a resin to some teeth to improve the occlusion (bite alignment) or to enhance cosmetics. This will be discussed with you as soon as it becomes apparent.

When should you see an orthodontist?
The need for orthodontics is best discovered when you are young. A dentist will have a good indication of whether or not your teeth will be straight when he sees you as a child 6 to 8 years of age. Most treatment would not begin until a patient is 8 years old, although in some cases, orthodontics can be started earlier.

It is easier to direct the movement of teeth in a child. Early tooth guidance is a very important phase of orthodontic care, which can take place even though all the permanent teeth are not yet in place. Certain problems are much easier to correct at this stage of a "mixed dentition" of baby and permanent teeth. An average case can last from 18 to 24 months.

While orthodontic therapy is admittedly easier in the child patient, you are never too old to begin orthodontics. The number of adults seeking orthodontic treatment has risen dramatically during the past decade. As long as you have healthy bone support for your teeth, you can have orthodontic therapy. Most adult cases take 18 to 24 months to complete.
What are retainers?
Once braces are removed, it is usually necessary to wear a retainer. After your braces come off, your orthodontist will make a mold of your mouth and produce a set of retainers. This retainer will maintain the new tooth alignment until the teeth have had a chance to become firmly set in their new positions. This retainer may be either removable or fixed in place. Aside from a permanent bonded retainer, there are two other types that most people get.

A Hawley Retainer is made of acrylic and metal. The acrylic goes behind your teeth and up against your upper palate; the metal is in front of your teeth. This is the most reliable refinements that still need to be done to your teeth.

Orthodontic Toothbrush
An Essix Retainer is clear plastic and looks like an Invisalign aligner tray. Many people want this type of retainer, but it has its disadvantages. Many orthodontists feel that because it covers the biting surface of your teeth, they do not "settle" properly after treatment. For this reason, sometimes orthodontists give a patient both types of retainers: an Essix Retainer to wear during the day when they are people-facing, and a Hawley Retainer to wear at night when they are home sleeping.

No matter what type of retainer you get, the most important thing is to wear it exactly as the orthodontist tells you. Most people need to wear their retainers 24/7 for at least 6 months, then switch to wearing it only at night when sleeping. 

How do I keep clean teeth with braces on?
While orthodontic treatment is in the active phase, that is, while the braces are on your teeth, you must be very diligent about keeping your teeth clean. This will be more difficult than and somewhat different from cleaning your teeth without braces. You will be instructed in the use of any cleaning aids needed. These may include dental floss threaders, orthodontic toothbrushes, an oral irrigator to flush out debris, proper brushing habits, fluoride mouth-rinses, and periodontal aids. You must follow your proper oral self-care routine each night to prevent decay, decalcification of the teeth, and gum disease. You also should not use a whitening toothpaste when you have braces. It could cause you to have "two tone" teeth after the brackets are removed. Another thing to remember is that although a device like a Waterpik is great for gum stimulation and dislodging food, it is not a substitute for flossing. You still need to floss daily.

Fixed and Removable Orthodontics

The traditional and stereotypical movie, television, and commercial vision of orthodontic treatment is one of yards of metal wire tied down to teeth so covered with silver bands and brackets that the whites of the teeth are barely visible. With today's advanced dental technology, this picture is far from accurate.

Tooth Alignment:
Changes in tooth alignment can be accomplished in several different ways. When appropriate, upper and lower arch expanders can be used to increase the curvature of the tooth-bearing supporting structures. These expanders are usually cemented into place and are not able to be removed by the patient. The expanders are often a prelude to fixed metal bands. They can be cemented to the teeth as well as longitudinal arch wires and springs and still be used to move teeth.

The look:
Some time ago, the desire of patients to show less metal resulted in the development of bonded tooth-colored and clear brackets (as opposed to the metal bands that completely surround a tooth). These brackets cover only about 25% of the tooth surface and are bonded into place. The trade-off with the more esthetic bonded brackets is a higher percentage of dislodgement of the bracket, requiring additional office visits for repair and replacement. The wires and springs are changed periodically to accomplish the various stages of movement. The metal components stay in place until the tooth movement is finished. Some dental conditions mandate the use of this traditional orthodontic process.

Removable:
Tooth-colored Braces
It is not always necessary to use fixed devices to move teeth. Less aggressive tooth movement can additionally be done with patient-removable appliances. Some are made of a gum-colored pink acrylic material with metal wires and springs embedded in them. These are worn by the patient except when he or she is eating, brushing, and flossing. The metal and plastic appliances do not show as much metal so they are somewhat more acceptable. The trade-off with removable appliances is that they only work when they are in the patient's mouth, making proper patient compliance a big issue. If you do not wear them, the teeth will not move as planned. The metal and plastic appliances are used in what is called minor tooth movement. Many orthodontic cases are not appropriate for removable appliance therapy.

Invisalign:
Several years ago, a new type of removable appliance therapy was developed and patented. Align Technology has a product called Invisalign. Clear, thin plastic aligners (positioners) are sequentially placed to move the teeth in a precise fashion. The aligners are left in the mouth as much as possible and removed only for eating, drinking, and cleaning the teeth. Again, if you do not wear them, the teeth will not move. The aligners are almost invisible when in place and are extraordinarily acceptable esthetically. They are indicated for adults and patients older than 14 years who have all permanent teeth in including fully erupted second molars. They can be used to treat simple to fairly extensive misalignment problems. Most cases are completed in about 12 months. Research is still in progress to determine the limits of this process.

The doctor who will be performing the orthodontic treatment will take these different modalities into consideration and develop a treatment plan best suited to your needs. Age of the patient, number of teeth involved, and extent of movement are primary factors in the decision-making process. Please be sure to ask why or why not one technique rather than another was suggested.
