    A dental sealant is one way that you can prevent cavities from developing on the chewing surface of your teeth. The sealant is a liquid plastic that is filled into the grooves of your back molars. The liquid hardens and forms a protective covering over the enamel of the tooth. The covering stops any existing bacteria in the grooves from forming acid because food cannot get stuck in the teeth anymore. With no acid in the plaque, cavities are less likely to develop. Dental sealants only need occasional repair, but can last up to 10 years. They are recommended to all children.
