Dental Sealants in Barrhaven
The chewing surfaces of your back teeth are covered in tiny grooves and pits — the perfect hiding spots for food and bacteria, and the most common place for cavities to form. Even diligent brushing can't always reach the bottom of those grooves. Dental sealants solve this beautifully, sealing off those vulnerable surfaces with a smooth protective coating. It's one of the simplest, most effective ways our Barrhaven team helps families across South Ottawa stay cavity-free.
What Are Dental Sealants?
A dental sealant is a thin, protective resin coating painted onto the chewing surface of a back tooth. In its liquid form, it flows into every groove and fissure, then hardens into a durable shield that bonds to the enamel. Once in place, the sealant keeps food particles and cavity-causing bacteria from settling into the deep grooves where decay typically starts. Sealants are clear or tooth-coloured, so they're virtually invisible and don't change how your teeth look or feel.
Why Sealants Are Worth It
Sealants deliver outsized protection for such a small, simple treatment.
Powerful Cavity Defence
Sealants block food and bacteria from settling into the deep grooves of back teeth where decay so often begins.
Fast & Painless
Applied in just minutes per tooth with no drilling, no freezing, and no discomfort at all.
Long-Lasting Protection
A single application can protect a tooth for years, and we check the seals at every routine visit.
Invisible & Comfortable
Clear or tooth-coloured sealants are unnoticeable and won't change how your teeth look or feel.
Smart Prevention
Preventing a cavity is far easier and gentler than treating one — sealants stop problems before they start.
Great for the Whole Family
Children, teens, and cavity-prone adults can all benefit from this simple protective treatment.
Who Should Get Sealants?
Sealants are a smart choice for anyone at higher risk of cavities on their back teeth, but they're especially valuable in a few situations:
- Children and teens as their permanent molars come in
- Kids and adults with deep grooves and pits in their back teeth
- Anyone with a history of cavities looking to prevent more
- Teeth that are healthy and free of existing decay or fillings
Sealants are a cornerstone of our children's dentistry and pair perfectly with regular cleanings. If decay has already taken hold, we'll discuss gentle cavity treatment instead. To read more on prevention, the Canadian Dental Association explains how sealants protect teeth.

Frequently Asked Questions
What exactly are dental sealants?
Dental sealants are thin, protective coatings applied to the chewing surfaces of back teeth (molars and premolars). They flow into the deep grooves where toothbrush bristles can't always reach, creating a smooth barrier that keeps food and cavity-causing bacteria out.
Are dental sealants only for children?
No. Sealants are especially valuable for children and teens as their permanent molars come in, but cavity-prone adults with deep grooves and no existing decay can benefit too. We'll let you know if sealants make sense for you at your Barrhaven visit.
Does getting sealants hurt?
Not at all. Applying a sealant is quick, completely painless, and requires no drilling or freezing. The tooth is simply cleaned, prepared, painted with the sealant, and hardened with a light — most people find it the easiest treatment they'll ever have.
How long do dental sealants last?
Sealants can protect a tooth for several years. They do gradually wear over time, so we check them at your regular cleanings and exams and reapply or touch them up as needed to keep the protection going strong.
Do sealants replace brushing and flossing?
No — sealants are an extra layer of defence, not a substitute for good habits. Brushing twice a day, flossing, and regular cleanings are still essential. Sealants simply protect the one area that's hardest to keep clean: the grooved chewing surfaces.
How much do dental sealants cost in Barrhaven?
Sealants are one of the most affordable preventive treatments available, and they can save you far more by preventing cavities. Our fees follow the Ontario Dental Association fee guide, we offer direct billing to most insurers, and we'll give you a clear estimate beforehand.
