Generally, teeth sealant is applied when a child’s permanent molars come in between the ages of 6 and 12. However, it is not uncommon to have baby teeth sealed especially if the enamel is week, has large pits or grooves in them. The baby teeth are more important than some people realize, if a baby tooth is decayed and not taken care of promptly the decay process can spread into the permanent teeth. Children are not the only ones that should have their teeth sealed, a teenager who rarely has a cavity or adults who have good healthy strong teeth should also consider having their teeth sealed for the extra protection.
