Professional teeth whitening, explained simply

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.

Your whitening journey, step by step

Your whitening consultation

We'll start with a quick chat about what you're hoping to achieve. Your dentist will check your teeth and gums to make sure whitening is safe and suitable for you - it's important your mouth is healthy before we begin.

Custom whitening trays made to fit

We'll take precise impressions of your teeth so a set of slim, comfortable whitening trays can be custom-made just for you. These hold the whitening gel snugly and evenly against your teeth.

Collecting your trays and gel

At your next visit, we'll fit your trays to make sure they're comfortable, and we'll show you exactly how to use them at home. You'll go home with everything you need to get started.

Whitening at home

You'll wear your trays with a small amount of whitening gel for a set time each day - either during the day or overnight, depending on which option suits your routine. Most patients see a noticeable difference within a couple of weeks.

Your follow-up check

We'll see you again to check on your results and make sure you're happy. If you'd like to go a touch lighter, we can talk through your options - and we'll give you advice on keeping your new smile bright for as long as possible.

Who is professional whitening for?

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:

Coffee, tea and wine staining
Yellowing from natural ageing
Smokers wanting fresher smiles
Pre-wedding or event prep

The team behind your brighter smile

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.

Your whitening questions answered in Twickenham

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.
