Dental Sealants
Invisible protective coatings for back teeth - up to 80% fewer cavities where they start.
- Painless, no-drill application
- Great for kids, teens & adults
- Lasts up to 10 years
Why 8 out of 10 cavities start in the grooves
- Grooves are narrower than a single bristle - toothbrushes physically cannot clean their depths.
- Food and bacteria park there after every meal, producing acid exactly where enamel is thinnest.
- New molars are immature enamel - a 6-year-old's first molar is at peak risk for years.
- Sealants close the door: a smooth, sealed surface cleans easily and starves the bacteria out.
That's why pit & fissure sealants in Thunder Bay are one of the highest-value preventive investments a parent can make - and one of the cheapest.
Sealant timing: who should get them and when
Ages 11-13
Second molars arrive - the last and deepest grooves in the mouth.
Teens
Any unsealed, cavity-free molar is still worth shielding through sugar-heavy years.
Adults
Deep grooves with no fillings? Adults benefit too - sealants aren't kids-only.
High-risk kids
History of cavities, braces, or dry-mouth conditions move sealants up the list.
Special needs
Patients who find brushing difficult gain the most from sealed, cleanable surfaces.
How sealants are placed - 10 minutes, zero pain
-
Clean & dry
The molar is cleaned and isolated so moisture can't interfere.
-
Gentle etch gel
A mild conditioning gel micro-textures the enamel so the sealant bonds.
-
Rinse & dry again
Thirty seconds - no drill, no needle, no vibration, ever.
-
Paint on the sealant
Liquid sealant flows into every groove and pit.
-
Cure & check
A blue curing light hardens it in seconds; bite and coverage are verified.
Most kids watch the whole process in the mirror - and leave surprised it's already done.
Sealants vs. fluoride vs. fillings
| Dental sealants | Fluoride varnish | Fillings | |
|---|---|---|---|
| Role | Physically block grooves | Chemically strengthen enamel | Repair a cavity |
| Pain / drill | None | None | Anesthetic + drill |
| Typical cost | $60-$90 per tooth | $30-$60 per visit | $150-$400+ per tooth |
| Lasts | 5-10 years | 3-6 months per application | 7-10 years |
| Best for | Deep grooves, new molars | All surfaces, risk-based | Already-decayed teeth |
The math is simple: a $75 sealant prevents a $300 filling - and a drill visit.
Are dental sealants safe? What about BPA?
Yes. Modern sealant materials are BPA-free or release amounts far below any safety threshold - decades of research and health-authority reviews (including CDC and Canadian dental bodies) confirm sealants as one of the safest, most effective cavity-prevention tools in dentistry. They're checked at every recall visit and can be repaired or reapplied if worn.
How long do dental sealants last?
Typically 5-10 years with normal chewing. We inspect every sealant at each recall visit - if one chips or wears, it's touched up in minutes, usually at no charge while intact coverage remains possible. Sealants plus fluoride varnish is the full-coverage prevention combo: grooves sealed, surfaces strengthened.
New molars? Seal them before school year cavities start.
