Teeth Whitening
Professional-grade whitening treatments to help reduce the appearance of staining
Professional teeth whitening uses higher-concentration bleaching agents than over-the-counter products and is carried out under the supervision of a dental professional, either in the clinic or through a take-home kit dispensed by a dentist. The treatment works by using peroxide-based solutions to lighten the shade of natural tooth enamel. Results depend on the original shade of your teeth, the type of staining present, and the whitening method used. Whitening is not effective on crowns, veneers, or composite restorations, and will not change their colour. Results are not permanent and vary between individuals.
What the Process Involves
- 1
Pre-treatment assessment — your dentist examines your teeth and gums to confirm suitability; whitening is not recommended if you have untreated decay, gum disease, or significant sensitivity.
- 2
Shade recording — your current tooth shade is documented as a baseline for comparison after treatment.
- 3
In-chair or take-home treatment — in-chair whitening involves applying a professional-strength gel to your teeth, often activated with a light or heat source, for one to several sessions; take-home kits use custom trays worn for a specified period each day.
- 4
Post-treatment review — your dentist may review your results and advise on maintenance or additional treatment if needed.
- 5
Ongoing maintenance — your dentist advises on avoiding foods and drinks that cause staining, and may recommend periodic top-up treatments to maintain your result over time.
Recovery
Tooth sensitivity is a common side effect of whitening, particularly during treatment and in the days immediately following. Gum irritation can also occur if the bleaching agent contacts soft tissue. These effects are generally temporary and resolve without intervention, though your dentist can recommend sensitivity relief products if needed.
Important Considerations
Whitening is not suitable for all patients — those with severe sensitivity, exposed root surfaces, or certain restorations may not be good candidates. It will not lighten existing crowns, veneers, or fillings, which may become more noticeable after treatment. Results are temporary and will fade over time, especially with consumption of staining foods and beverages. Overuse of whitening products or using excessively high concentrations can cause tooth damage. Only consult a registered dental professional for whitening advice and treatment.
