This one-page handout uses a question and answer format to educate people about the use of sealant to prevent tooth decay. It explains that a sealant is a coat of plastic material the dentist can apply on the top or biting surfaces of the back teeth, which creates a barrier to seal out decay-causing bacteria in plaque. The document outlines how plaque causes cavities, and how sealants can prevent them. It discusses who should get sealants, including children with newly formed permanent teeth.
