    Dental Sealants for Kids: What Parents Should Know

    Dental sealants are thin, protective coatings applied to the chewing surfaces of back teeth (molars) to prevent cavities. According to the American Academy of Pediatric Dentistry, sealants can reduce the risk of decay in molars by up to 80%. They are one of the most effective and least invasive preventive treatments available in pediatric dentistry.

    How Dental Sealants Work

    The American Academy of Pediatric Dentistry describes sealants as follows:

    "Sealants protect the grooved and pitted surfaces of the teeth, especially the chewing surfaces of back teeth where most cavities in children are found. Made of clear or shaded plastic, sealants are applied to the teeth to help keep them cavity-free."

    The chewing surfaces of molars have deep grooves (called pits and fissures) where food particles and bacteria can become trapped. Even thorough brushing may not reach the bottom of these grooves. A sealant fills in these grooves, creating a smooth surface that is much easier to keep clean.

    The Sealant Procedure

    Applying sealants is quick, painless, and requires no drilling or anesthesia:

    1. The tooth is cleaned and dried
    2. A mild solution is applied to slightly roughen the surface (this helps the sealant bond)
    3. The tooth is rinsed and dried again
    4. The liquid sealant is painted onto the chewing surface
    5. A curing light is used to harden the sealant in seconds

    The entire process takes only a few minutes per tooth. Your child can eat and drink normally right after the appointment.

    When Should Children Get Sealants?

    The Canadian Dental Association and AAPD recommend considering sealants at these key stages:

    • Around age 6 — when the first permanent molars (6-year molars) come in
    • Around age 12 — when the second permanent molars (12-year molars) come in
    • Earlier if needed — some children with deep grooves in their baby molars may benefit from sealants before age 6

    The sooner sealants are applied after the molars erupt, the better — this protects the teeth during the most cavity-prone years.

    How Long Do Sealants Last?

    Sealants can last several years with normal wear. Dr. Gumber checks your child's sealants at every regular checkup and can reapply them if they become worn or chipped. Even a partially worn sealant provides some protection.

    Are Sealants Safe?

    According to the Ontario Dental Association, dental sealants have been used safely for decades. The amount of BPA exposure from dental sealants is minimal — far less than what a person encounters from everyday food containers and receipts.

    The CDA, ODA, and AAPD all recommend sealants as a safe and effective part of a child's preventive dental care.
