Dental sealants are used to prevent the formation of cavities on permanent molars and bicuspids. It is a preventive treatment that consists of applying a thin layer of sealant on the chewing surface of these teeth.
How is the sealant applied?
Applying sealant is comparable to placing a white filling. The main difference is that there’s no need for anaesthesia, since no drilling is required.
- The tooth is cleaned and, if needed, cavities are eliminated
- The surface of the tooth is prepped
- The liquid sealant is applied
- A blue light is used to harden the sealant
Why is sealant applied to molars and bicuspids?
The natural grooves on the surface of these large teeth are difficult to properly clean, since a toothbrush’s bristles can’t reach deep enough. Food particles and plaque accumulate there, making it easier for cavities to form.
Is this procedure for everyone?
Patients under the age of 15 are at higher risk of developing cavities. Patients aged 6 to 15 are more prone to have dental sealant applied to their molars and bicuspids. A baby tooth whose grooves are very deep could also benefit from this. For adults, dental sealant helps protect the enamel of their teeth.
