Sealants

What is it?

Dental sealant is a plastic, professionally-applied material placed on the chewing surfaces of children’s back teeth to prevent cavities. When combined with the use of fluoride, it can prevent most tooth decay in children.

How does it work?

Sealants form a physical barrier to cavity-causing bacteria that can invade the pits and fissures on the chewing surfaces of teeth. By placing sealants on your child’s first permanent molars shortly after they erupt from the gum—at about 6 years of age—you can protect them from developing caries in areas of the teeth where food and bacteria collect.
