Sealants

Preventing tooth decay has now become even easier. Sealants protect the surfaces of the teeth with grooves and pits, most importantly the chewing surfaces of new permanent first molars (6 year old molars) where most cavities are found in children. Made of clear or slightly shaded plastic, sealants create a barrier between the tooth and the decay causing bacteria that live in plaque and cause the formation of cavities.

What is plaque and why does it cause cavities?

Children eat and drink during the day, and the food in their mouth combines with bacteria producing a sticky film known as plaque which attaches to the surfaces of the teeth. Plaque is most difficult to remove on the back teeth of new molars which have deep grooves and pits. If plaque is not removed, it produces acids which attack the tooth enamel and create cavities.

How can sealants help prevent cavities?

Coating the teeth with a plastic material fills in the small grooves and pits, preventing plaque from sticking into these areas - reducing the risk of forming cavities.

Is it difficult to apply sealants?

No. There are no needles or drilling necessary. The material is painted on and a special light is used to harden the material.

Which teeth should be sealed?

The teeth most at risk of decay are the 6 and possible 12 year old molars. They have the deepest grooves and pits and are the most difficult to keep clean.

Who should get sealants?

Sealants are most effective in reducing cavites in children with newly formed permanent teeth. They will prevent the formation of decay. An application of sealants is a preventive measure to keep teeth healthy. No needles or drilling is required.
