Professional Boutique whitening at our friendly St Margarets practice - a gentle, dentist-supervised way to lift years of staining and bring a fresh new sparkle back to your smile.


Professional teeth whitening is a safe, dentist-supervised treatment that lifts staining and discolouration from your teeth using a gentle whitening gel. Unlike over-the-counter strips or supermarket trays, the system we use - Boutique Whitening - is a clinically tested, professional-grade treatment that's safer, kinder to your gums and far more effective than anything you can buy on the high street.
For lots of patients in Twickenham and St Margarets, whitening is the easy, affordable first step into cosmetic dentistry. It doesn't change the shape of your teeth - it simply gives them back the brightness they had before years of tea, coffee, red wine and life in general had their say.
Whitening suits a wide range of patients, particularly anyone looking for a quick, affordable lift to their smile without changing the shape of their teeth.
It works well for:
Whitening at St Margarets Smiles is provided by our team of dentists, who'll start by checking your teeth and gums to make sure whitening is safe and right for you. We're a friendly, family-led practice with over 25 years of history in St Margarets, and we take real care to do whitening properly - safely, gently and with results in mind.
We'll also often recommend a session with our hygienist Rachael Kayibanda before you start, as a thorough professional clean (including Airflow polishing where appropriate) can lift surface staining and help your whitening results go even further.

Professional whitening is one of the simplest ways to refresh your smile - no drilling, no injections, no permanent changes. Just a brighter, more confident you.

We're a fairly priced family practice and we believe cosmetic dentistry should feel within reach. You can find full pricing on our fee guide page.
Professional whitening at St Margarets Smiles starts from £400, which includes your consultation, custom trays and Boutique Whitening gel. The final cost depends on which whitening option you choose and whether you'd like to combine it with a hygiene appointment or Airflow polishing first.

Is teeth whitening safe?
Yes, when carried out under the supervision of a dentist. The Boutique Whitening system we use is a clinically tested, professional-grade product that's gentle on enamel and kind to your gums. We always assess your mouth carefully before starting to make sure whitening is safe and right for you.
Will whitening damage my enamel?
No - professional whitening doesn't damage healthy tooth enamel when used correctly. The active ingredient (a low-strength peroxide gel) gently breaks down stain molecules within the tooth structure without removing any tooth material.
How long do whitening results last?
Most patients enjoy the results of professional whitening for around 1 to 3 years, depending on lifestyle. Coffee, tea, red wine and smoking will all shorten how long your results last. We'll provide top-up gel guidance so you can refresh your shade whenever you'd like.
Will whitening work on crowns, veneers or fillings?
No - whitening only works on natural tooth structure. If you have crowns, porcelain veneers or white fillings on your front teeth, we'll talk through this carefully at your consultation, as your natural teeth may end up lighter than your existing dental work.
Does whitening hurt?
Most patients experience nothing more than mild sensitivity, which usually settles within a day or two. We can adjust the strength of the gel and the length of wear time to suit you, and we'll always check in to make sure you're comfortable.
Do you offer Airflow polishing too?
Yes - we offer Airflow polishing, which uses a fine spray of water, air and very fine powder to remove surface staining from coffee, tea, red wine and smoking. It's a wonderful complement to whitening, and many patients have a session with our hygienist before starting to maximise their results.
Do you accept whitening patients from outside St Margarets?
Yes, we welcome patients from across the TW1 postcode and the wider Richmond upon Thames borough - including East Twickenham, Isleworth, Whitton and Strawberry Hill. We're a short walk from St Margarets train station with pay-and-display parking right outside.
