Sealants are most effective when applied shortly after the first and second set of permanent molars erupt—typically around ages 6 and 12.
At DentiFlow Dentistry in Thornhill, we offer dental sealants as a simple, effective way to protect teeth from cavities—especially in children and teens. Sealants are a quick, non-invasive preventive treatment that helps shield the chewing surfaces of molars from bacteria and plaque buildup. By acting as a barrier, sealants significantly reduce the risk of tooth decay and support long-term oral health.
Dental sealants are thin, protective coatings made of a safe composite resin that are applied to the grooves and pits of back teeth (molars and premolars). These areas are naturally more prone to trapping food and bacteria, which can lead to cavities—even with good brushing habits.
Once applied, the sealant hardens to form a shield that prevents plaque and acid from penetrating the enamel.
Sealants can reduce the risk of decay in molars by up to 80%, especially in the years when children are most cavity-prone.
Preventing dental cavities helps avoid the need for future fillings, root canals, or more complex dental treatments.
Sealants offer extra protection during a child’s most cavity-susceptible years, usually between ages 6 and 14.
Here’s what you can expect during your sealant appointment at DentiFlow:
The tooth is thoroughly cleaned to remove any plaque or debris from the grooves.
A gentle etching solution is applied to the chewing surface to help the sealant bond effectively.
The liquid sealant is brushed onto the tooth and carefully spread into the pits and grooves.
A special curing light is used to harden the sealant within seconds, creating a durable, protective barrier.
Sealants are most effective when applied shortly after the first and second set of permanent molars erupt—typically around ages 6 and 12.
Teens with deep grooves in their molars or a history of cavities can also benefit from sealants.
While more common in children, sealants can also help adults who are prone to decay or have vulnerable chewing surfaces.
Avoid sticky or hard foods for 24 hours after placement to allow the sealant to fully set.
Maintain good oral hygiene—sealants protect the chewing surface but brushing and flossing are still essential.
Attend regular checkups so we can check the condition of the sealants and reapply if necessary.
Sealants can last up to 5–10 years, but may wear down over time and need replacement.
