PIT AND FISSURE SEALANTS
What are sealants?
Sealants are a safe and painless way of protecting your teeth from decay. A sealant is a protective plastic coating, which is applied to the biting surfaces of the back teeth. The sealant forms a hard shield that keeps food and bacteria from getting into the tiny grooves in the teeth and causing decay.
Which teeth should be sealed?
Sealants are only applied to the back teeth - the molars and premolars. These are the teeth that have ‘pits' (small hollows) and ‘fissures' (grooves) on their biting surfaces.. Some teeth naturally have deep grooves which will need to be sealed; others have shallow ones which will not need sealing.
How long do pit and fissure sealants last?
Sealants usually last for many years, but your dental team will want to check them regularly to make sure that the seal is still intact. They can wear over time, and sometimes the dental team needs to add or replace some sealant to be sure that no decay can start underneath it.
How do pit and fissure sealants work?
The sealant forms a smooth, protective barrier by covering all the little grooves and dips in the surface of the tooth. Dental decay easily starts in these grooves if they are not sealed.
When should this be done?
Sealants are often applied as soon as the first permanent teeth start to come through. This is usually between 6 and 7 years of age. The rest are usually sealed as soon as they appear which can be any time between 11 and 14 years of age.
Do I still have to clean my teeth?
Yes. It is still very important to do this. The smooth, sealed surface is now much easier to keep clean and healthy with normal brushing.
