Treatments - Fissure Sealants

Deep pits and grooves can be found on the chewing surfaces of the back teeth. Such pits and grooves are termed ‘fissures’ and are usually so narrow that toothbrush bristles and streams of water are not able to clean them effectively. These form a favourable environment for bacteria to flourish, often resulting in tooth decay.

What can be done?

Fissure sealants can be applied to your tooth to seal off pits and fissures from the oral environment. Sealing the tooth surface protects fissures from bacteria and fermentable foods like sugar and starches to prevent decay from starting deep within the fissures. Any tooth with pits and fissures can be treated, provided the surface to be filled is sound and has not been previously filled. The most commonly treated teeth are the molars and premolars.

How are sealants applied?

Sealants are applied easily and painlessly, no drilling is required. The tooth is properly cleaned, treated, dried, and the sealant applied. A very bright light is then used to harden the sealant to form a protective coating over the tooth.
