Pit and fissure sealants are very effective in preventing decay on the chewing surfaces of the back teeth. The grooves or pits and fissures in these molars are often deep and narrow, making it difficult and sometimes impossible for the toothbrush to clean thoroughly. At the same time, young children also lack the dexterity to brush these hard to reach areas. Left undisturbed, bacteria can cause a cavity in molar teeth.
The best way to prevent tooth decay in molars is to seal the pits and fissures. It is recommended that sealants be placed on six year old and 12-year molars as soon as they erupt.
The process is simple. The pit and fissure sealant is painted onto the tooth and flows into the pits and crevices to bond with the enamel. No dental anaesthetic is needed and no tooth material is removed.
