Teeth Whitening
A simple, effective way to achieve a brighter, more confident smile.
Professional teeth whitening can safely lighten your natural teeth, reducing staining and discolouration to give you a noticeably brighter smile.
At Gallions Reach, your whitening treatment is professionally supervised by our dental team and tailored to achieve a natural-looking result that suits you.

Professional teeth whitening at our South-East London clinic
Teeth can naturally become darker over time, while everyday things such as tea, coffee, red wine and smoking can contribute to staining and discolouration.
Professional teeth whitening provides a safe and effective way to brighten your smile without changing the shape or structure of your natural teeth.
At Gallions Reach, we’ll assess your teeth before treatment, discuss the result you’d like to achieve and provide everything you need to whiten your teeth gradually at home.
A brighter smile, made simple
Our professional whitening treatment uses custom-made trays that fit comfortably over your teeth, together with professional whitening gel.
You’ll use your trays at home for a prescribed period each day, gradually lightening your teeth until you achieve the desired result.
Because your treatment is planned and supervised by a dentist, we’ll make sure your teeth and gums are suitable for whitening before you begin and explain exactly how to use your whitening system safely.

How does teeth whitening work?
Before starting treatment, we’ll check the health of your teeth and gums and discuss what you’d like to achieve.
We’ll then create custom-made whitening trays that fit comfortably over your teeth. At home, you’ll place a small amount of professional whitening gel into the trays and wear them for the recommended amount of time each day.
Your teeth will gradually become lighter over the course of treatment, allowing you to achieve a brighter smile while retaining a natural appearance.
It’s important to remember that whitening only changes the colour of natural teeth. Crowns, veneers, bridges and fillings won’t become lighter, so we’ll discuss any existing dental work with you before treatment begins.

Who is teeth whitening suitable for?
Anyone with healthy gums who would like to improve their smile can undertake a teeth whitening treatment. If you have stains on your teeth from tobacco, coffee, tea and many other substances, our service is highly effective at removing them.
Is teeth whitening bad for your teeth?
Teeth whitening treatments, when administered and supervised by an experienced dentist, are perfectly safe and do not pose any risk to the health of your teeth. There’s a chance your gums will be sensitive to the chemicals used in the process. If this is a concern to you, please speak to us about it at your appointment. .
Is the whitening process compatible with dentures and veneers?
Our whitening treatment is designed to enhance the natural whiteness of the enamel on your teeth. If you have restorations in place, such as dentures, crowns and veneers, they will not lighten with this process. You may need to consider replacing pre-existing dental work if you wish for any restorations to match the new shade of your natural teeth.
Are you fully qualified to deliver this treatment?
Yes. We are registered with the General Dental Council and qualified to deliver teeth whitening treatments. Our dentists are highly experienced, and they frequently refresh their training.
How long will the effects of the treatment last?
Teeth whitening is not permanent and you will need to look after your teeth once the process is finished. If you are able to avoid coffee, smoking and other activities that discolour your teeth, you may retain the effects for up to 2 or 3 years. Typically, around 12 to 18 months can be expected.
Is professional teeth whitening safe?
Yes. When prescribed and supervised by a dental professional, teeth whitening is a safe way to lighten natural teeth. We’ll check that your teeth and gums are healthy and suitable for whitening before treatment begins.
How long does teeth whitening take?
Most patients whiten their teeth gradually at home over a period of around two weeks, although the exact treatment time will depend on your starting shade and the result you’d like to achieve.
How white will my teeth become?
Everyone’s teeth respond differently to whitening. Rather than aiming for an artificial-looking shade, we’ll help you achieve a brighter result that still looks natural.
Will teeth whitening make my teeth sensitive?
Some people experience temporary sensitivity during whitening treatment. If this happens, your dentist can advise you on how to manage it and, where appropriate, adjust how frequently you use your whitening trays.
Will whitening change the colour of crowns, veneers or fillings?
No. Teeth whitening works on natural tooth enamel and won’t change the colour of crowns, veneers, bridges or fillings.
If you have visible restorations, we’ll discuss this with you before treatment so you understand how whitening could affect the overall appearance of your smile.
