My dentist has advised a fissure sealant, what is that

Fissures are the grooves on the biting surfaces of back teeth. Often, if these grooves are deep, food and bacteria can be trapped and this can lead to decay.

Modern preventive dentistry now allows us to flow a white or clear sealant material into these grooves to seal them. Sealants do not harm the tooth and are ideally placed in childhood when a permanent tooth has fully erupted into the mouth.

The procedure does not involve any injections or drilling and it can be done by your dentist or therapist.
