Sealants are a thin coat of composite resin applied to cover pits and grooves on the back of teeth as a means to prevent tooth decay. These natural grooves are located in areas that are difficult to reach with a toothbrush. As a result plaque can build up and over time cause tooth decay which eventually forms a cavity. Cavities can lead to larger problems such as abscesses in teeth which could ultimately lead in the tooth having to be removed.

Sealants are usually tooth-coloured and cannot be seen when you talk or smile. Placement of preventive resins is very conservative and does not require anesthesia or removal of natural teeth and can be done in as little as a few minutes per tooth. Repair or replacement of lost or chipped sealants is recommended to maintain effectiveness.
