Fissure Sealants


 

What are fissure 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 and fissures on their biting surfaces. The pits and fissures harbor bacteria that cause decay and are too deep and narrow for even one tooth brush fibre to reach. Its best to seal these teeth as soon as they grow into the mouth, usually from around six years old.

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 a bright light onto it. (see diagrams)
