A professional fluoride application may be recommended to support cavity prevention when your individual risk calls for it.
A preventive addition
Topical fluoride may be applied as varnish, gel or another professional product. It complements daily fluoride toothpaste; it does not replace brushing or restore a tooth with a large cavity.
Make the plan personal
Ask what raises your cavity risk and why this product is being suggested. Tell the clinician about dry mouth, recent cavities and products you already use. Recommendations for children should account for age.
Follow the product instructions
Eating, drinking and brushing instructions depend on the product. Ask for those directions before leaving, the proposed repeat interval and whether the application has a separate fee.
Costs and coverage in Canada
Your cost depends on the proposed plan and your situation. Request a written estimate showing each stage, laboratory fees and follow-up. CDCP coverage depends on program rules, eligibility and the exact service. Confirm your share before treatment.

- What did the examination show, and what are my options?
- What are the benefits, risks and alternatives in my case?
- How many visits are expected, and who handles follow-up?
- What is included in the estimate, and what will I pay?
