What are cavity-fighting sealants?

The American Dental Association cites sealants as an effective weapon in the arsenal against tooth decay. Sealants are a thin coating painted on chewing surfaces of molars and premolars. Dental sealants act as a barrier, protecting your teeth against decay-causing bacteria.

Sealants have proven effective with both adults and children, but are most commonly used with children. Despite the fact that sealants are about half the cost of fillings, only a small percentage of school-aged children have sealants on their permanent teeth. Ask your dentist whether sealants are a good choice for you or your children.
