Sealants

A sealant is a hard plastic coating applied to the pits and fissures (grooves) on the chewing surfaces of premolars and molars.  It is used as a barrier to protect the grooves from decay where toothbrush bristles cannot clean.

  • Sealants are best done as the teeth come through in the mouth on newly erupted teeth before bacteria have a chance to form decay.
  • Provided the sealant stays intact, it can protect the grooves for many years.  Regular check-ups are necessary to assess the sealants to ensure they have not chipped or decay is not forming underneath.
  • Sealants require no injection or drilling and are relatively easy to place so they are comparatively lower cost than having a filling done.
  • Sealants can be clear, white or tooth coloured

 

 

 


Preventive Resin Restorations (PRRs)

The PRR is similar to the fissure sealant and is commonly performed when there is evidence or possibility of decay in the grooves.  The PRR is commonly done on teens and adults, on teeth with grooves that are ‘stained’ – meaning there is a good chance of finding decay deep in the groove.

The grooves are initially investigated and any decay present is carefully removed prior to bonding a very minimal filling. In most cases the decay can be completely removed without discomfort and without the need for injection. 

Once the decay is fully removed the tooth is filled with a tooth coloured composite resin filling using conventional bonding techniques. This makes a durable, white filling in the groove which is sealed very effectively to the enamel.

It is best that a PRR is done early; almost immediately once the tooth has fully emerged from the gum and prior to any serious decay getting established in the grooves.  As with restorations, sealants and PRRs are also best placed using rubber dam.
