Teeth whitening in London.
A safe procedure that lightens the colour of your teeth with a dental bleaching agent. A good solution for staining from foods, drinks, smoking and certain medications.
Two ways to whiten
In the chair in an hour, or at home over two weeks.
In practice · Results in about an hour
Power whitening
A protective barrier is placed on your gums and lips, and a whitening gel on your teeth. A lamp positioned over the teeth activates the bleaching process, with results expected within one hour.
At home · Results over two weeks
Home whitening
We custom-make a lightweight mouth tray that fits snugly over your teeth. Whitening gel goes inside the tray, worn overnight or during the day, with results normally seen over two weeks.
Individual results vary, based on your initial tooth colour and the nature of your staining.

Is it right for you?
Whitening works on natural teeth, and on certain kinds of staining.
Staining from foods, drinks, smoking and certain medications usually responds well. Your result depends on your initial tooth colour and the nature of the staining, which is exactly what we assess at your consultation.
Crowns, veneers and fillings do not change shade with whitening, so if your smile includes restorations we plan the order of treatment carefully: whiten first, then match the new work to the brighter shade.

Keeping the shade
Three habits that make results last.
Mind the culprits
The same foods, drinks and smoking that caused the staining will bring it back fastest.
See the hygienist
Regular scale and polish visits lift surface staining before it settles in.
Top up at home
Your custom trays can be reused for top-ups, agreed with your dentist.

Common questions
Before you ask.

It depends on your habits: the same foods, drinks and smoking that caused the staining bring it back fastest. Hygienist visits and top-ups with your custom trays, agreed with your dentist, keep the shade.

Whitening at the practice is carried out by GDC-registered clinicians with a protective barrier over your gums and lips, after an assessment of your teeth and staining.
Can I spread the cost?+
Yes: easy payment facilities are available, and treatments over £500 qualify for 0% finance over 12 months.
