Pits and Fissure Sealants

Pit and fissure sealant, also called SPF, consists of the application of an organic polymer that adheres to the surface of tooth enamel. SPF is a preventative process which aims to protect enamel against tooth decay.

What is the procedure ?

Used for several years, this technique consists of first applying a phosphoric or nitric acid in the form of gel or liquid to the chewing surface of the tooth to be treated. Once the enamel is cleaned and dried, the sealant is applied. This must be hardened using blue light. Properly applied and maintained SPF can last for many years.

Should you put sealants on your teeth or those of your children?

Pit and fissure sealants can be helpful for everyone. We usually suggest sealants to children with a tendency to decay, or if the teeth demonstrate an anatomy conducive to the development of it. The enamel of a newly erupted tooth (around 6 or 7 years for first molars, and 10-13 years for second molars) is not as mineralized as that of an adult. For this reason, enamel is more fragile and often requires additional protection obtained by the application of a pit and fissure sealant.
