Teeth Whitening
At Sweet Tooth Dental, we offer professional teeth whitening treatments at our Christchurch, St Albans, and Rangiora clinics. We are committed to achieving natural-looking results while protecting the health of your teeth and gums.
Why Is Professional Teeth Whitening Important?
Tooth discolouration is a gradual process that develops over time and may be caused by:
- offee, tea, and red wine
- Smoking or tobacco use
- Certain foods and drinks
- Natural ageing
- Some medications
- Previous dental trauma
Some stains remain on the surface of the teeth, while others develop deeper within the enamel. A thorough dental assessment helps determine the most suitable whitening option for your teeth.
Professional teeth whitening at Sweet Tooth Dental is carried out under professional supervision to help achieve a brighter smile while protecting your tooth enamel.

Professional Teeth Whitening Options
To improve the colour of your teeth safely and evenly, we offer different professional teeth whitening treatments at Sweet Tooth Dental.
In-Clinic Teeth Whitening
In-chair whitening is performed at the dental clinic using professional-grade whitening products. Treatment is carefully monitored to help achieve brighter results in less time.
Take-Home Whitening Kits
We also provide customised whitening trays for use at home. These trays are custom-made to fit your mouth and help brighten your teeth gradually over a period of days or weeks.
We will recommend the most suitable option based on your goals, tooth sensitivity, and any existing dental work.
What to Expect During Teeth Whitening Treatment
Consultation and Assessment
Before whitening, we assess the condition of your teeth and gums to ensure they are healthy. Existing fillings, crowns, or other dental work may affect the outcome and will be discussed before treatment begins.
Whitening Treatment
The whitening product is carefully applied according to the chosen treatment method. Some patients achieve their desired result after one treatment, while others may require additional sessions.
Aftercare Advice
Some patients may experience temporary sensitivity following treatment. We provide aftercare guidance to help maintain results and minimise sensitivity.
Is Teeth Whitening Safe?
When performed by dental professionals, teeth whitening is considered a safe procedure. Professional-grade products help minimise the risk of gum irritation and uneven whitening.
Over-the-counter whitening products do not always provide predictable results and may increase tooth sensitivity if used incorrectly.
At Sweet Tooth Dental, patient safety and realistic treatment expectations are always discussed before whitening begins.
Maintaining Your Whitening Results
Some patients maintain their whitening results longer than others, depending on their lifestyle habits.
To help maintain your results:
- Brush and floss regularly
- Attend regular dental check-ups
- Limit staining foods and drinks
- Avoid smoking where possible
- Follow your dentist’s aftercare instructions
Over time, some patients choose occasional touch-up treatments to maintain the brightness of their smile.
