Dental Sealants & Fluoride in Ottawa
Two of the simplest, most effective ways to prevent cavities — quick, painless and covered by the CDCP for eligible patients.
The chewing surfaces of back teeth have deep grooves where food and bacteria hide, and that is where most childhood cavities begin. A sealant is a thin, protective coating painted into those grooves to seal them off. It takes just minutes per tooth, with no needles or drilling.
Fluoride strengthens enamel and helps reverse the very earliest stages of decay. A professional fluoride varnish applied at a checkup gives teeth an extra boost — helpful for children, and for adults with dry mouth, gum recession, sensitivity or a history of cavities.
Sealants and fluoride are among the preventive services covered by the Canadian Dental Care Plan for eligible patients, including children under 18. We bill the plan directly.
