Professional teeth whitening in Teddington
Professional teeth whitening in Teddington at Kirby Dental uses bespoke take-home kits from Boutique and Enlighten, supervised by your dentist so the result is even and your gums are protected. Most people see a clearly brighter smile over a short course of daily wear at home. Medically reviewed by Dr Farah Rajabali, Principal Dentist, GDC No. 193825. Last updated 22 June 2026. Whitening lifts years of staining from tea, coffee, red wine and age, and because a dentist plans and supervises it, it is safer and more predictable than a shop-bought kit.
How professional teeth whitening works
Whitening uses a controlled dose of hydrogen peroxide or carbamide peroxide that passes into the enamel and breaks down the stain molecules inside the tooth. A dentist checks first that your teeth and gums are healthy, then has custom trays made so the gel sits evenly against your teeth and away from your gums. You wear the trays at home, day or night, over a short course, and the colour lifts gradually.
Your whitening options at Kirby Dental
We offer two dentist-supervised take-home systems, and we will help you choose at your consultation.
- Boutique Whitening Flexible and effective, with day and night gel options to suit your routine.
- Enlighten Whitening The premium choice, known for taking teeth to the lightest shade they will naturally reach.
Both use bespoke trays made from a scan of your teeth, so the fit is comfortable and the result is even.
What results can you expect?
Most people notice a clearly brighter smile over a short course of regular wear, with Enlighten aiming for the lightest natural shade. Results vary from person to person depending on the type of staining, your diet and your genetics, and whitening lifts the colour of natural teeth rather than turning them an artificial white. Occasional top-ups keep your smile bright over the following months. You can see real results in our smile gallery.
Is teeth whitening safe?
Professional whitening is safe when a dentist plans and supervises it. In the UK, tooth whitening is a legally protected procedure that can only be carried out by a registered dental professional, which is why high-street and beauty-salon whitening is both riskier and, at the concentrations that actually work, unlawful. A dentist screens for decay and gum problems first, protects your gums with a proper tray fit, and manages any sensitivity. Mild, short-lived sensitivity is the most common side effect and usually settles quickly.
Whitening, bonding or Invisalign?
Whitening changes the colour of your natural teeth, not their shape or position. If your teeth are healthy and straight but stained, whitening is usually all you need. If you also want to reshape chips or close small gaps, composite bonding may be added afterwards, and crooked teeth are better straightened first with Invisalign. We will give you an honest recommendation rather than upselling. You can see the full range on our cosmetic dentistry page.
Keeping your smile white
Good habits make whitening last. Cut down on tea, coffee, red wine and other staining drinks, or use a straw, and rinse with water afterwards. Brush twice a day, keep your regular hygiene appointments, and avoid smoking. Use any remaining gel for occasional top-ups as your dentist advises.
FAQs
How much does teeth whitening cost in Teddington?
The cost depends on which system you choose and your starting shade. Your dentist talks you through the options at your consultation and gives you a clear plan and price before anything goes ahead, and finance is available to spread the cost. Whitening is one of the more affordable cosmetic treatments compared with veneers.
How long does teeth whitening last?
Whitening usually lasts from several months to a couple of years, depending on your diet and habits. Tea, coffee, red wine and smoking shorten it. Occasional top-ups with your custom trays keep your smile bright, which is far easier than starting again.
Is teeth whitening near me safe to do at home?
Dentist-supervised take-home whitening is safe because your dentist checks your teeth first and makes trays that fit precisely. Unregulated DIY or salon kits are riskier and, at effective strengths, can only legally be provided by a dental professional in the UK. Always have whitening overseen by a dentist.
Will whitening work on crowns, veneers or fillings?
No. Whitening only lifts the colour of natural teeth, so crowns, veneers and white fillings stay the shade they were made. If you have restorations at the front of your mouth, we will plan around them, and you may choose to replace older ones to match your whitened teeth.
Does whitening cause sensitivity?
Some people get mild, short-lived sensitivity during whitening. It usually settles within a day or two, and using a sensitivity toothpaste and spacing out the gel helps. Because your treatment is dentist-supervised, we can adjust the plan if your teeth feel sensitive.
