Dental sealants are used to protect the chewing surfaces of teeth. They are generally applied to decay-prone surfaces of back molars and pre-molars. Sealants come in a liquid form that quickly hardens to form a shield over these chewing surfaces.
The most important reason for getting sealants is to avoid tooth decay. The chewing surfaces of the back teeth are typically rough and uneven with small pits and grooves, making them the ideal place for cavities to start. Bacteria in the mouth change the sugar in food to acid, which can start a cavity in the tooth.
At Appleby Dental Professionals we recommend that children get sealants on their permanent molars as soon as the teeth come in – before decay has a chance to attack the teeth.
