A dental sealant is a protective coating that is bonded to the grooves of the teeth, creating a barrier in the decay-prone “pits and fissures” of teeth.

Tooth sealants are an excellent preventative measure to protect all posterior (back) teeth that do not have clinical signs of decay. They are especially useful on the first and second molars. Children can begin with sealants between the ages of 5-7 when the first molars erupt. The second molars follow at ages 11-14 and can receive sealants at that time. Adults that have no previous decay on the biting surfaces of their molars (or fillings, crowns, etc…) can also have sealants.

Why Are Dental Sealants Necessary?

Many teeth have tiny grooves that form as they develop. These are pits and fissures. This is where most decay occurs. That’s because the bristles of a toothbrush can’t get down into the grooves to remove the food and bacteria that get trapped there. By forming a thin covering over the pits and fissures, sealants keep out plaque and food, and thus decrease the risk of decay.
