Eruption Patterns of Teeth: Part 2 (Adult Teeth)

Permanent Teeth

The enamel of the permanent teeth actually begins forming at 3 to 4 months of age. If your water is not fluoridated, make sure your baby receives the necessary fluoride supplements. Permanent teeth come in under the baby teeth. Pressure from the upward movement of the permanent tooth causes a resorption of the root of the baby tooth. When the root disappears, the tooth gets loose and eventually falls out. If the permanent tooth does not come in directly under the baby tooth, the baby tooth root will not resorb and not loosen. The second tooth will come in either in front of or behind the baby tooth. This is common. When it happens, see the dentist to determine whether the baby tooth should be removed to permit the proper positioning of the permanent tooth.
