Children: Fluoride applications and fissure sealants for protection against decay

 

What about children?

The aim is to prevent dental disease rather than treat it at a later date.
Fluoride applications and fissure sealants (tooth coloured sealants) are applied to biting surfaces of children's teeth to prevent decay.

 

What are sealants?

Sealants are a safe and painless way or protecting your children’s 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.

 

What is involved?

The process is usually quick and straightforward taking only a few minutes per 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 an ultraviolet light onto it.


How long do they last?

Sealants usually last for many years, but your dentist will want to check them regularly to make sure that the seal is still intact. They can wear over time, and sometimes the dentist needs to add or replace some sealant to be sure that no decay can start underneath them.

 

How do they 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.
 

When should this be done?
Sealants are often applied as soon as the 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.
