ental sealants are thin plastic coatings that are applied to the grooves on the chewing surfaces of the back teeth to protect them from tooth decay. Sealants protect the chewing surfaces from tooth decay by keeping germs and food particles out of these grooves.
A sealant can last for as long as 5 to 10 years. A sealant is better than waiting for a tooth to decay because decay damages teeth permanently. Sealants protect them.
Sealants can save time, money, and the discomfort sometimes associated with dental fillings. Fillings are not permanent. Each time a tooth is filled, more drilling is done and the tooth becomes a little weaker.
