Applying a dental sealant to the molars of your children when they are between the ages of 5 and 7 can protect their molars from decay. A dental sealant is a thin layer of liquid that hardens and creates a barrier between the teeth and the plaque, food particles and bacteria that collect on them and lead to decay.
The procedure is simple. It begins when an adhesive is applied to the teeth that are to be treated. The sealant is spread over the adhesive as a liquid. The liquid hardens, creating a protective barrier. Sealants last for about 10 years and can be reapplied if necessary.
