The most common cavities occur in the grooves located on the posterior teeth. These grooves are difficult to clean and act as a good hiding place for the bacteria and the sugars which cause cavities. A Sealant is a white material which can be placed into thesegrooves to help prevent cavities from forming there. Sealed posterior teeth are easier to clean and make it more difficult for the bacteria to get access to the sugars they need to create cavities.

Because they are placed on healthy tooth structure prior to the formation of a cavity no numbing is required to place a protective Sealant. Most sealants are successful for 10 or more years.
