A brighter, whiter smile can transform your confidence. Our professional whitening treatments deliver safe, effective results that shop-bought kits simply can't match.
Book Your ConsultationWhy Professional Whitening?
Over time, teeth naturally lose their brightness. Coffee, tea, red wine, smoking, and even the ageing process can leave your smile looking dull and discoloured. While shop-bought whitening products promise quick results, they contain far lower concentrations of active ingredients — and some unregulated products can actually damage your teeth.
Professional whitening from a qualified dentist is the only safe, legal, and genuinely effective way to whiten your teeth in the UK. We use carefully formulated gels with custom-fitted trays to deliver even, natural-looking results — supervised every step of the way.

Why Do Teeth Become Stained?
Surface Stains
These sit on the outer enamel layer and are caused by everyday habits — coffee, tea, red wine, dark-coloured foods, smoking, and certain medications. A professional hygiene appointment can remove some surface staining, but deeper discolouration requires whitening treatment.
Below-the-Surface Stains
These occur within the tooth structure itself and can result from ageing, certain antibiotics taken during childhood, excessive fluoride exposure, or trauma to a tooth. They're harder to address and may require more intensive whitening or alternative cosmetic treatments such as veneers or composite bonding.
During your consultation, we'll assess the type and severity of your staining and recommend the most effective approach.
How Professional Whitening Works
Consultation & Assessment
We'll examine your teeth and gums, discuss your goals, and take a shade reading to record your current tooth colour. We'll explain what level of whitening is achievable and address any questions you have. Any underlying issues — cavities, gum disease, worn enamel — will need to be treated first for your safety.
Custom Tray Fabrication
Digital impressions or moulds are taken to create bespoke whitening trays that fit precisely over your teeth. This ensures the whitening gel is applied evenly and stays away from your gum tissue. You'll collect your trays along with your professional-grade gel at a follow-up appointment.
At-Home Whitening
Apply a small amount of gel to your custom trays and wear them for a specified period each day — typically between 30 minutes and a few hours, depending on the product. Treatment usually continues for two to four weeks. Many patients prefer to wear their trays overnight, while others fit them around their daily routine.
Review & Results
After completing the course, you'll return for a review. We'll compare your new shade against the original reading and ensure you're happy with the results. Most patients achieve a noticeable improvement of several shades, resulting in a brighter, fresher-looking smile.

Maintaining Your Results
With good care, professional whitening results can last anywhere from one to three years. How long depends on your lifestyle and habits.
To keep your smile bright, limit consumption of staining foods and drinks — or rinse with water after consuming them. Avoid smoking, maintain good oral hygiene with twice-daily brushing and regular flossing, and attend regular hygiene appointments to remove surface staining.
One of the great advantages of the take-home tray system is that you can do occasional top-up treatments. Your custom trays last for years, and purchasing additional gel from us is simple and affordable — far cheaper than repeating the full treatment.
Whitening Pricing
We offer two professional whitening options to suit your needs and budget. Both include custom-made trays and professional-grade whitening gel.

Will whitening damage my teeth?
No. When performed professionally with approved products, whitening is safe and does not damage enamel. Problems only arise with unregulated products or improper use — another reason to always choose a qualified dental professional.
Will it hurt?
Some patients experience temporary sensitivity during treatment, particularly to cold food and drinks. This is usually mild and resolves quickly once treatment is complete. We may recommend a desensitising toothpaste before and during treatment to minimise any discomfort.
How white will my teeth get?
Results vary depending on the type and severity of staining and your natural tooth colour. Most patients achieve a noticeable improvement of several shades. During your consultation, we'll give you a realistic expectation of what's achievable for your teeth.
How long do results last?
Typically 1–3 years depending on your lifestyle. Regular hygiene appointments and occasional top-up treatments help maintain your brighter smile. Because you keep your custom trays, top-ups are quick and affordable.
Can I whiten if I have crowns or veneers?
Crowns, veneers, and fillings won't change colour with whitening. If you have visible dental work, we'll discuss this during your consultation and plan treatment so your smile looks natural and even.
Is whitening toothpaste just as effective?
Whitening toothpastes can help maintain results and remove some surface stains, but they don't contain the active ingredients needed to change the actual colour of your teeth. For genuine whitening, professional treatment is the only effective option.
Who can have teeth whitening?
Most adults with healthy teeth and gums are suitable. Whitening is not recommended during pregnancy or breastfeeding, and under-18s cannot legally receive whitening treatment in the UK. Active decay or gum disease must be treated first.
