Pit and fissure sealants are plastic coatings that are used to prevent decay on the chewing surfaces of the back teeth. The grooves or pits and fissures in our molars are often deep and narrow, making it difficult for the toothbrush to clean thoroughly. The best way to prevent tooth decay in molars is to seal those pits and fissures. It is recommended that sealants be placed on molars as soon as they erupt.
At Dr. Sunny Yuen’s Scarborough/Markham dental office, the process is simple. We place the dental sealants onto the tooth so that it flows into the pits and crevices to bond with the enamel. No local anaesthesia is needed and no tooth material is removed. The sealants help by shielding the tooth from plaque and food particles, protecting it from future decay.
