What is the definition or description of: sealants?

Preventive Dentistry: Sealants are non-invasive preventive fillings placed by a dentist or hygienist in the bite surface grooves of molar and bicuspid teeth to prevent cavities. The grooves in these teeth are usually the first place for tooth decay to start as they are so small that even the bristles of a tooth brush cannot clean them. The sealant is painlessly painted in the grooves and protects the teeth.

Cavity prevention: Posterior permanent teeth have deep grooves and crevices on the chewing surface. This is the most common area to get a cavity on these teeth. Dental sealants are a composite material that is flowed into these areas to make them "shallow valleys" so food and bacteria can't get stuck in these grooves, thus making it harder to get a cavity. Sealants are cost effective and easy for the patient.

Tooth Protection: Sealants are a non-invasive preventive coating painted into the deep grooves and crevasses of teeth (usually molars) by a dentist or hygienist to prevent food and germs from getting stuck there and therefore reduce the chance of cavities on these teeth by about 80%. Sealant placement is painless and cost effective. They usually last several years and are easy to touchup if needed.

Cavity Prevention: Dental sealants help reduce the risk of developing cavities on the biting surfaces of teeth.
