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.

The process is usually quick and straightforward, taking only a few minutes for each tooth. The tooth is thoroughly cleaned, prepared with a special solution, and dried. The liquid sealant is then applied and allowed to set hard – usually by shining a bright light onto it.

No, it is totally pain-free.

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 need to add or replace some sealant to be sure that no decay can start underneath it.

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.

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.

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. Using a fluoride toothpaste, last thing at night and at least one other time during the day, will help to protect your teeth. Pit and fissure sealing reduces tooth decay and the number of fillings you might need.
