We recommend doing sealants when the molars are at risks for developing cavities. Most molars contain small ridges and grooves that make it difficult to remove the plaque that causes cavities, even with regular brushing and flossing. Many of these ridges are smaller than the bristles on a toothbrush, and can be very challenging to keep clean.

A dental sealant is a protective coating that is applied to the molars once they emerge to protect them from bacteria containing plaque. While fluoride should be used to protect all the surfaces of the teeth, sealants add extra protection against cavities on the chewing surfaces on the back molars. This can prevent unnecessary cavities, fillings and damage to these important teeth that are particularly prone to tooth decay.
