Fissure sealants explained

Fissure sealants are used on the molar teeth and can prevent cavities from forming in the grooves of the tooth. Even if there is already some decay, your dentist can apply fissure sealants and prevent any further damage from being done.

It is like putting a protective coat of varnish on wood, and gives the tooth an added layer of protection. The sealant can be seen on the teeth if the white one is used, but there are also clear sealants which cannot be seen once they have been applied.

What are the steps involved in dental fissure sealants procedure? 

  • The first part of the process is the cleaning of the tooth thoroughly, which is why a dental hygienist will often carry out this procedure.
  • Once the teeth are clean, they will then be dried
  • Then it is time to prepare the surface of the teeth to ensure that there is a good bond with the sealant.
  • The fissure sealant is then painted onto the surface of the tooth and allowed to fill the cracks of the molars.
  • It is hardened using intense light.
  • Once the sealant is hard, it is then checked, and any excess material is removed from the surface of the tooth by polishing.
  • And they will also check that it does not affect the bite.

How long do they last? 

Dental fissure sealant has a lifespan of about ten years, although it will need to be checked regularly by your dentist.

Over time, the sealant can be chipped away and worn through chewing and grinding, but any damage to the sealant can be repaired easily.
