Sealants are protective, composite plastic material that is placed directly on the chewing surface of the tooth just after the adult tooth has erupted. Sealants drastically reduce the occurrence of tooth decay and prevents the enamel from eroding.
When applying the sealants, the tooth is thoroughly cleaned, then the surface of the tooth is roughened to better help the sealant adhere to the tooth’s surface. The sealant is then placed on the tooth, and a special light is used to help harden the material. With proper care, sealants can last up to several years before needing to be reapplied.
