Sealants

Dental sealants are thin plastic coatings that are applied to
the grooves on the chewing surfaces of the back teeth to
protect them from tooth decay. Most tooth decay in children
and teens occurs on these surfaces. Sealants protect the
chewing surfaces from tooth decay by keeping germs and
food particles out of these grooves.

Permanent molars are the most likely to benefit from
sealants. The first molars usually come into the mouth
when a child is about 6 years old. Second molars appear
at about age 12. It is best if the sealant is applied soon
after the teeth have erupted, before they have a chance
to decay.

A sealant can last for as long as 5 to 10 years. Sealants
should be checked at your regular dental appointment
and reapplied if they are no longer in place.
