What are Sealants?
The premolar and molar teeth are the largest teeth in the mouth. They have a larger surface area and have several grooves and pits on the chewing surface. These grooves can be deep and are a prime place for plaque and acid to build up and cause cavities. It is for this reason that many dentists will suggest applying sealants, especially on young children. A sealant is a coating that is applied to the chewing surface of the teeth creating a smooth surface to act as a barricade protecting it from decay.
Applying a sealant is a quick and easy procedure. It does not involve any anesthetic. After the teeth are cleaned, a chemical liquid is applied to the tooth. This will clean the tooth chemically from any decay process. The etching allows the sealant to bond with the tooth. The sealant is then applied in a liquid form and a light is applied to the surface of the tooth to speed up the hardening process. Sealants can be reapplied every 5 to 10 years. Sealants are very effective in preventing decay and in some cases can prevent additional damage where decay has already begun.
