Retainers help maintain tooth position after orthodontic treatment. Wear, fit and replacement need a plan tailored to your appliance.
Fixed and removable designs
A retainer may be removable or bonded behind teeth. The orthodontist chooses the design and wear schedule. A retainer has a different purpose from an active aligner or sports mouthguard.
When it no longer fits
Contact the practice if the appliance is lost, damaged or no longer seats as expected. Avoid forcing a painful retainer into position. Bring the appliance to the assessment when possible.
Plan for care and replacement
Ask for cleaning and storage instructions for your material. Clarify whether replacement scans, a new appliance and follow-up adjustments are included in your original plan or billed separately.
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.
