Fissures are the deep grooves within the biting surfaces of the back teeth that can be difficult to keep clean because they are so narrow. Every time you eat or drink, food and bacteria can enter the fissures, which can eventually lead to tooth decay. Fissure sealants help prevent decay by protecting teeth with a safe plastic coating to stop food and bacteria from stagnating in the fissures.
Sealants are normally applied to permanent teeth as they start to come through (usually between 6-7 years) and will continue to be applied when further teeth start to show.
What does treatment involve?
It is quick, easy and comfortable to apply a fissure sealant, with no need for anaesthetic or drilling. The tooth is cleaned and prepared with a special solution. This is followed by application of the liquid sealant which is then hardened with a bright light to form a protective layer over the tooth.
A fissure sealant can last for many years with the correct maintenance and care. However, regular dental checks are important in order to maintain the condition of your sealants and pick up any problems early.
