Dental Sealants

Tooth Decay often occurs on the chewing surfaces of the back teeth. The good news is that sealants can protect these surfaces from tooth decay and improve the chances to stay filling-free.​

What causes tooth decay?

Your teeth are coated with a sticky film of bacteria called plaque (Pronounced PLACK). The bacteria converts the sugar you eat and drink into acids that attack the strong, outer layer of your teeth, called enamel.

Over time, this can weaken the enamel and causes cavities.


Sealants? What is that?

Most parents are not very well informed of what a sealant can do for your child's teeth. A sealant is a material applied to the chewing surfaces of your back teeth and then hardens, Once your teeth are covered, food and plaque can not get in.  Sealants work as shields that fight against acids attacks.


How are Sealants applied?

Your teeth are cleaned and the chewing surfaces are prepared to help the sealant stick to your teeth. The sealants are painted onto the chewing surfaces where it bonds to your tooth and hardens. Sometimes a special light is used to help the sealant harden. It usually takes only a few minutes per tooth.
