Dental sealant is just usually called sealant, it's a protective coating placed on any tooth that may be at higher risk of developing cavities.

Typically children have sealants placed on their back teeth, molars and premolars to protect their teeth.

It is a special resin that is applied as a liquid over the teeth and is then hardened with a special light.

Dental sealants are typically applied to the back teeth as they have a higher tendency to be missed by brushing, leaving bacteria free to soak up any sugary food residue and go on to cause cavities.

Your dental hygienest will normally apply the dental sealant and is a quick and painless procedure undertaken in just one visit.
