A dental sealant is a plastic coating applied to the chewing surfaces of back teeth. Grooves in these teeth are so narrow that a toothbrush cannot fit into the spaces to remove plaque (the biofilm of bacterium that causes decay in the mouth). Dental sealants prevent dental decay in these grooves.  Teeth with restorations already present would not benefit from sealants. Children should receive sealants on permanent molars as soon as they erupt (about ages 6 and 12 years).

Sealants can provide 100% protection from dental decay or "cavities" on the chewing surface. Research has shown that when placed over very minimal dental decay, the decay will no longer progress.  

Sealants take only a few minutes to apply.  First the teeth are cleaned and the chewing surfaces are conditioned to help the sealant to adhere to the tooth. The sealant is then “painted” onto the enamel surface, where it bonds directly to the tooth and hardens. We may use a curing light to help harden the surface quicker.

We check the integrity of the sealants every time you have a checkup and reapply them if necessary.  We warranty sealants for a period of three years.  Sealants hold up well  under the force of normal chewing and usually do not have to be replaced unless excessive sticky foods are eaten.

Sealants are not just for children.  Adults can also be at risk for this type of decay and benefit from sealants as well.   

Ask us if you or your child would benefit from sealants.
