Applying fissure sealants on the grooves of back teeth is a safe, painless, and quick way to prevent tooth decay. As it is usually clear or white in colour, it is unnoticeable. Once applied, fissure sealants can last for many years and they make brushing easier, as the tooth surface becomes smoother. We check at each appointment and seal again if they are worn. Please remember though, fissure sealants are just one of the preventions, so it is still important to brush and floss every day.
