Understanding the Treatment

What is teeth whitening?

Teeth whitening is a safe, non-invasive cosmetic treatment that lightens the natural colour of your teeth by removing stains and discolouration built up over the years from coffee, tea, red wine, smoking and ageing.

At Smilespark in Greenwich, whitening is always carried out or supervised by a registered dentist. We use professional-strength whitening gel that is far more effective — and far safer — than over-the-counter strips or unregulated salon treatments.

Whether you choose our in-surgery treatment for instant results or a take-home kit you can use at your own pace, you'll get a noticeably brighter, natural-looking smile without damaging your enamel.

Frequently Asked

Teeth whitening questions.

How much does teeth whitening cost in Greenwich?
At Smilespark in Greenwich, in-surgery teeth whitening is £200 and our take-home whitening kit is £250. Both include a free consultation and are fully supervised by our dental team. Finance options provided by third-party lenders may be available, subject to status.
Is teeth whitening safe?
Yes. Professional teeth whitening carried out or supervised by a registered dentist is a safe, well-established treatment. In the UK only dental professionals can legally whiten teeth. We assess your teeth and gums first and use enamel-safe professional gel — unlike many over-the-counter or salon products.
What's the difference between in-surgery and home whitening?
In-surgery whitening is done in a single appointment at our Greenwich practice for fast results. The home kit uses custom-made trays and professional gel so you can whiten gradually at your own pace over a couple of weeks. Many patients combine both for the best, longest-lasting result.
How long do teeth whitening results last?
Results typically last from several months up to a couple of years depending on your diet and lifestyle. Cutting down on coffee, tea, red wine and smoking helps. With a home kit you can simply top up whenever your smile needs a refresh.
Does teeth whitening hurt?
Most patients feel little or no discomfort. Some experience mild, temporary sensitivity that settles within a day or two. Because your whitening is dentist-supervised, we tailor the treatment to keep you comfortable throughout.
Where is Smilespark and what are your hours?
Smilespark Dental Practice is based in Greenwich, South East London (SE7). We're open Monday to Saturday, 9am–6pm. Call or email us to book your free teeth whitening consultation.
