Woodbridge Smile Centre offers a very simple and practical solution to prevent cavities in the first place: dental sealants. It is a preventive treatment recommended for children, teens, and even adults who are more likely to develop cavities.

Dental sealants are thin protective coatings, usually made from a special tooth-safe resin, that are painted onto the deep grooves of your back teeth. Sealants flow into these deep areas like a liquid, then harden into a protective shield. This way, it stops cavities before they have a chance to form.
Dental sealants are recommended for children soon after their first and second permanent molars erupt, usually between the ages of 6 and 14. Teenagers and adults with healthy molars that have deep grooves but no existing decay may also benefit.
During your dental examination, we’ll evaluate your teeth and let you know whether sealants are a good preventive option for you.
| Benefit | Description |
|---|---|
| Prevents Cavities | Creates a barrier that keeps bacteria and food debris from settling into deep grooves. |
| Quick and Comfortable Treatment | The entire procedure usually takes only a few minutes per tooth and requires no drilling or injections. |
| Completely Painless | The sealant is simply painted onto the tooth surface, making the process easy for children and adults alike. |
| Protects Hard-to-Clean Teeth | Molars become easier to clean because the chewing surfaces are smoother after treatment. |
| May Reduce Future Dental Costs | Preventing cavities can help you avoid more extensive restorative treatments in the future. |
| Suitable for Many Patients | In addition to children, sealants can also benefit many adults with healthy molars. |
The entire process is very comfortable and can often be completed during a routine dental visit.
Furthermore, we work with most private and public insurance providers and directly send your claims to them. Association-based insurance plans are also accepted. Moreover, CDCP-eligible patients can use their benefits for more affordable dental care. If you’re uninsured, you can use our flexible payment plans

Dental sealants prevent cavities before they start. Fillings, on the other hand, are used after a cavity has formed. In short, sealants help you avoid needing fillings in the first place.
It depends on the plan. Private dental insurance in Canada often covers sealants for children under 18 (as preventive care), but not always for adults. Also, CDCP covers sealants only for clients 17 years and under (on specific teeth, lifetime limit of 2 per tooth).
No, most modern sealants are either clear (transparent) or tooth-colored. This means they’re white or lightly tinted to match your enamel.
