Sealants are a preventative procedure that help to reduce the risk of cavities in molars, premolars, or any teeth with deep grooves. The sealant fills in the spaces on the chewing surface of the tooth where decay causing bacteria grow. It is recommended that children and teens get sealants after the emergence of the six-year molars. Adults may also get sealants to prevent decay on teeth with deep grooves as well. The exam checks for abnormalities of the face, neck, lips, tongue, throat, tissues, and gums.
