A sealant is a protective, plastic material that is placed directly on the chewing surfaces of molars and premolars. Sealants protect tooth enamel from erosion and drastically reduce the occurrence of tooth decay.
Teeth are prepared for sealants with a thorough cleaning, followed by the application of a specialized dental solution. This solution roughens the chewing surfaces, making it easier for the sealants to adhere to the teeth. The sealants are then painted on the chewing surfaces of the teeth and a curing light is used to harden the sealants.
As long as the teeth receive regular care, sealants can last several years before requiring a reapplication.
