All molar teeth (baby and adult back teeth) have grooves which are naturally present in the teeth, these groves are called ‘fissures’. In some cases, these grooves are very deep and make it easier for the food / plaque to retain in these grooves causing the tooth to decay. Research heavily concludes that the use of fissure sealants in deep fissures reduces the risk of dental caries in mouth.
Fissure sealants are a preventive treatment for the teeth. Fissure sealants are a flowable resin material like the white filling material (composite) that helps prevent the food retention in the grooves. Early sealant of adult teeth can prevent a lifetime of fillings if well placed and maintained.
