Teeth Whitening
Professional-grade whitening treatments that deliver noticeably brighter results — safely, comfortably, and tailored to your smile.
Brighter results than anything over the counter
Over-the-counter whitening strips and toothpastes use low concentrations of bleaching agents that produce modest, slow results — if any. Professional teeth whitening uses higher-grade formulations applied under clinical supervision, delivering significantly more dramatic and longer-lasting brightness in far less time.
At Comfy Denture & Hearing Clinic, we offer custom take-home whitening trays fabricated from impressions of your teeth. The precise fit ensures the whitening gel stays in contact with every surface evenly, minimising gum irritation and maximising results.
Why choose professional whitening?
Stronger formulation
Professional whitening gels contain higher concentrations of carbamide or hydrogen peroxide than any retail product, producing faster and more uniform results.
Custom-fitted trays
Trays made from impressions of your teeth fit precisely, keeping the gel evenly distributed and away from your gums — reducing sensitivity and improving effectiveness.
Supervised & safe
We assess your teeth and gums before treatment to confirm whitening is appropriate for you and to identify any restorations that will not respond to bleaching.
Long-lasting brightness
With proper maintenance and occasional top-up treatments, professional whitening results can last one to three years.
Treats multiple stain types
Professional whitening is effective against coffee, tea, wine, tobacco, and age-related yellowing — the most common causes of tooth discolouration.
Convenient take-home use
Custom trays let you whiten at home on your own schedule — typically one to two hours per day over one to two weeks — with no clinic chair time required.
Is teeth whitening right for you?
Whitening works best for certain types of discolouration and certain patients. Here is what to consider before your consultation.
Extrinsic staining
Whitening is most effective on surface stains caused by food, drink, and tobacco. Age-related yellowing also responds well to professional bleaching.
Healthy teeth and gums
Active decay or gum disease should be treated before whitening. We will assess your oral health at your consultation and advise accordingly.
Natural tooth structure
Whitening agents work on natural enamel only. Crowns, veneers, bonding, and tooth-coloured fillings will not change shade — a factor to consider if you have visible restorations.
Realistic expectations
Intrinsic staining from tetracycline antibiotics or fluorosis may not respond fully to bleaching. We will give you an honest assessment of the results you can expect.
Your whitening journey
Consultation & shade assessment
We photograph and record your current tooth shade, examine your teeth and gums, and confirm that whitening is the right treatment for your goals.
Impressions for custom trays
Precise impressions of your upper and lower arches are taken to fabricate trays that fit your teeth exactly — the foundation of an effective take-home treatment.
Tray fabrication
Your custom whitening trays are made in our laboratory from thin, flexible material that is comfortable to wear and holds the gel securely against every tooth surface.
Take-home treatment
We provide your whitening gel and walk you through the application process. Most patients wear their trays for one to two hours daily over one to two weeks, depending on the desired result.
Review & maintenance
We review your results and provide guidance on maintaining your new shade — including dietary tips and a top-up schedule to keep your smile bright long-term.
