Sealants provide an extra layer of protection against tooth decay for both kids and adults. Sealants act as a barrier protecting enamel against plaque and acids and are applied to the chewing surfaces of premolars and molars. Although sealants offer extra protection against tooth decay, they do not replace brushing and flossing.

Your dentist can easily apply sealants in minutes and they usually last several years before needing to be reapplied.
