Dental Sealant in Montreal – Effective Protection Against Cavities

What Is a Dental Sealant?

A dental sealant is a thin resin coating applied to the grooves on the chewing surfaces of the back teeth (molars and premolars). Its main purpose is to help prevent cavities in vulnerable areas where food particles and bacteria tend to collect and where a toothbrush has difficulty reaching.

Why Get Dental Sealants?

The natural pits and fissures of the back teeth can trap food and make plaque removal challenging. Even with good oral hygiene, these areas are more prone to decay. Dental sealants:

  • Create a protective barrier against bacteria and food particles

  • Significantly reduce the risk of cavities

  • Are especially beneficial for children and teenagers when permanent molars erupt

  • Help maintain long-term oral health

Regular dental checkups, including professional cleanings and inspections with tools like the intraoral camera, allow your dentist to monitor sealants and reapply them when needed.

How Are Sealants Applied?

The procedure is simple, quick and completely painless. It is usually completed in a single visit:

  1. Thorough cleaning of the tooth to be sealed

  2. Preparation of the surface with a special gel for proper adhesion

  3. Application of the liquid sealant into the grooves of the tooth

  4. Hardening of the material with a special curing light

  5. Checking the bite and making any necessary adjustments

You can eat and drink normally immediately after the procedure.

Who Should Get Dental Sealants?

  • Children and teens as soon as their permanent molars appear

  • Adults who have a higher risk of developing cavities in their back teeth

  • Patients with a history of cavities who want to prevent future decay

This preventive measure can be combined with other periodontal care such as periodontal treatments to optimize overall gum and tooth health.
