Dental sealants provide a protective barrier over your teeth to prevent cavities. Brushing and flossing alone are not able to clean out the pits and grooves of the tooth surface to remove food and plaque. Sealants are usually applied to the back teeth, premolars, and molars, where decay most often occurs. The sealant will protect tooth enamel from plaque and acid that are naturally found in the mouth. As long as the sealant remains intact, the tooth surface will be protected from decay.
Sealants are quick and painless to apply and do not cause any discomfort. Your dentist or hygienist will paint the sealant directly onto the tooth. Each application of sealants usually lasts for a few years. If you have had sealants applied in the past, your dentist can check the condition of the sealants and reapply them when necessary.
