A brighter smile, safely and professionally

Professional teeth whitening from our GDC-registered dental team — a safe, regulated way to lighten the natural colour of your teeth.

What is professional teeth whitening?

Teeth whitening is a cosmetic dental procedure that uses regulated bleaching agents to lighten the natural colour of your teeth. The active ingredient — hydrogen peroxide or carbamide peroxide — penetrates the enamel to break down staining compounds and produce a lighter overall shade.

Professional whitening uses products that contain regulated concentrations of bleaching agents, prescribed and overseen by a dentist. This is fundamentally different from over-the-counter whitening toothpastes, strips, or products sold online, which either contain lower concentrations or, in some cases, unregulated substances that may cause harm.

At Castle Bromwich Dental Care, whitening treatment is only recommended following a clinical assessment to confirm your teeth and gums are healthy enough for treatment. We will always give you an honest assessment of what results may be achievable for you.

UK Regulation — Important

In the UK, the legal limit for hydrogen peroxide in tooth whitening products supplied to patients is 6%. Products containing more than 0.1% hydrogen peroxide may only be used by or under the prescription of a GDC-registered dentist. Products sold outside dental settings that exceed this are illegal and potentially dangerous. Castle Bromwich Dental Care uses only compliant, clinically approved whitening products.

Your whitening options

Treatment options we offer

We offer two main approaches to professional teeth whitening, which can be used individually or in combination depending on your teeth, timeline, and desired outcome. Your dentist will discuss which option is most appropriate for you.

Home whitening

Custom-fitted whitening trays are made from impressions of your teeth at the practice. You wear these at home with a prescribed whitening gel for a set period each day or overnight, typically over two to four weeks. Trays fit precisely to minimise gel contact with gums, treatment pace can be adjusted to your sensitivity, and trays can be kept for future top-ups.

In-practice whitening

A higher-concentration whitening gel is applied directly to the teeth in the practice under the supervision of your dentist. Typically completed in a single appointment of around one to two hours, with gum tissue carefully protected throughout. Often combined with home whitening for optimal results.

Cosmetic-dentistry

The degree of lightening achieved varies between patients. Results cannot be guaranteed and depend on the original shade and type of staining present. Tooth sensitivity following treatment is common and usually temporary.

What whitening will and won't change

Professional whitening can produce noticeable results for many patients with naturally discoloured teeth. However, whitening does not work on dental restorations such as crowns, veneers, bridges, or tooth-coloured fillings — these will remain their original shade.

Results vary significantly between individuals and are not permanent. We will discuss what may be achievable for you before you commit to treatment.

Suitability

Is teeth whitening right for you?

Professional whitening is suitable for many adults, but it is not appropriate for everyone. A clinical assessment is always required before treatment can be recommended.

logo yellow pink blue green plain symbol

Healthy teeth and gums

No active decay or gum disease. Any issues are treated first.

logo yellow pink blue green plain symbol

Natural discolouration

Yellowing due to food, drink, or ageing typically responds well.

logo yellow pink blue green plain symbol

Surface staining

Tea, coffee, red wine, or tobacco staining can often be lightened.

logo yellow pink blue green plain symbol

Realistic expectations

An honest understanding of the degree of change achievable for you.

logo yellow pink blue green plain symbol

Not during pregnancy

Whitening is not recommended during pregnancy or whilst breastfeeding.

logo yellow pink blue green plain symbol

Adults only

Professional whitening is only appropriate for patients aged 18 and over.

Whitening may have limited effect on tetracycline staining or fluorosis, and existing crowns, veneers, or fillings on front teeth may become more visibly mismatched. If treatment is not appropriate, we may discuss alternatives such as porcelain veneers or composite bonding.

The treatment journey

What to expect at Castle Bromwich Dental Care

From your first appointment to the end of your treatment, we will keep you fully informed at every stage. Your specific plan will depend on which option is most suitable for you.

1

Initial consultation & oral health assessment

Your dentist will examine your teeth and gums, review your dental history, and discuss your concerns. Any decay or gum disease must be treated before whitening can begin — see our dental hygiene page. We will be honest if whitening is unlikely to meet your expectations.

2

Shade recording & treatment planning

Your current tooth shade is recorded using a shade guide to provide an objective baseline. Your dentist will recommend the most appropriate whitening option and explain the expected outcome, duration, and costs.

3

Impressions for custom trays (home whitening)

If home whitening is recommended, precise impressions of your upper and lower teeth are taken so custom-fitted trays can be made. Trays are usually ready to collect within a few days. In-practice whitening does not require this step.

4

Whitening treatment

For home whitening, you will be given your trays, gel, and detailed written instructions. For in-practice whitening, your gums will be carefully protected before the gel is applied by your dental team.

5

Progress review

We may arrange a review to assess your progress, check for sensitivity, and compare your shade against the baseline. Adjustments to the plan can be made at this stage if needed.

6

Aftercare guidance & maintenance

Once complete, we will advise on how to maintain your results and discuss whether future top-up treatments may be appropriate. Whitening results are not permanent and will fade gradually over time.

Maintaining your results

How to care for your whitened teeth

Whitening results are not permanent. How long they last depends on your diet, lifestyle habits, and oral hygiene routine.

logo yellow pink blue green plain symbol

Avoid the "white diet" period

For 48 hours after whitening, avoid staining foods and drinks — tea, coffee, red wine, berries, tomato-based sauces, and dark sodas. Enamel is more porous immediately after treatment.

logo yellow pink blue green plain symbol

Maintain good oral hygiene

Brush twice daily with a fluoride toothpaste and floss regularly. A clean tooth surface is more resistant to staining.

logo yellow pink blue green plain symbol

Limit staining substances

Use a straw for cold drinks where possible and rinse with water after staining foods or drinks to slow restaining.

logo yellow pink blue green plain symbol

Avoid smoking

Tobacco rapidly reverses whitening results. Stopping smoking will help maintain your outcome and benefit your overall health.

logo yellow pink blue green plain symbol

Attend routine check-ups

Regular examinations and professional hygiene appointments help remove surface staining before it becomes embedded.

logo yellow pink blue green plain symbol

Consider periodic top-ups

If you retained your custom trays, periodic top-ups using prescribed gel from our practice can help maintain your results over time.

Tooth sensitivity is a common side effect of professional whitening and is usually temporary, resolving within a few days of completing treatment. Using a sensitivity toothpaste before and during treatment may help. If sensitivity is severe or persistent, stop treatment and contact us for advice.

Comparing your options

What whitening can and cannot do

Teeth whitening is effective for many types of discolouration but has limitations. We will always be transparent about what is and is not achievable for you.

Type of discolouration
Likely response
Notes
Food & drink staining (tea, coffee, wine)
Generally responds well
Surface staining typically lightens effectively with professional treatment.
Age-related yellowing
Often responds well
Natural yellowing of enamel over time is one of the most common reasons patients seek whitening.
Tobacco staining
Variable response
Results can be achieved but may be less predictable; stopping smoking is strongly advised.
Tetracycline antibiotic staining
Limited effect
This intrinsic discolouration is often resistant to whitening; veneers may be more appropriate.
Fluorosis (white spots/mottling)
Variable & unpredictable
May improve background shade but can sometimes make white spots more noticeable.
Crowns, veneers, bridges, fillings
Does not whiten
Restorations will not change shade — a mismatch with natural teeth may become more apparent.
Single dark or non-vital tooth
Different approach needed
May require internal (walking) bleach by a dentist — external whitening alone is unlikely to be effective.

Frequently asked questions

1. Is professional teeth whitening safe?

Yes — whitening carried out by a GDC-registered dental professional using regulated products is considered safe for the majority of suitable patients. The most common side effects are temporary tooth sensitivity and mild gum irritation, which typically resolve within a few days. We will assess your suitability and discuss all risks before treatment begins.

2. How much whiter will my teeth become?

This varies considerably between individuals and cannot be guaranteed. The degree of lightening depends on your original shade, the type of staining, the method used, and how your teeth respond. We will give you an honest assessment at your consultation using your baseline shade as a reference point.

3. Will whitening work on my crowns or veneers?

No. Bleaching agents do not alter the colour of dental restorations — including crowns, veneers, bridges, and tooth-coloured fillings. These will remain their original shade while your natural teeth lighten, which can sometimes create a visible colour difference.

4. How long do results last?

Results are not permanent and vary between patients. For many people, results last from several months to around two years, depending on diet, lifestyle, and oral hygiene. Top-up gel when advised can help to extend your results.

5. Is teeth whitening painful?

Whitening is not usually painful, but tooth sensitivity is a common side effect, particularly during or immediately after treatment. This typically resolves within a few days. Let your dentist know if you already have sensitive teeth so we can adjust the protocol or recommend a sensitivity toothpaste.

6. Can I whiten my teeth if I am pregnant or breastfeeding?

No. As a precautionary measure, we will not carry out whitening treatment during pregnancy or whilst breastfeeding. If you are planning a pregnancy, it is worth completing any whitening treatment beforehand.

7. Why is salon whitening unsafe?

Teeth whitening in a salon, beauty clinic, or similar non-dental setting is illegal in the UK. Non-dental practitioners are not qualified to assess your oral health, manage complications, or use products of the regulated concentration required. Illegal whitening has been associated with chemical burns, nerve damage, and infection.

8. Do I need healthy teeth and gums to have whitening?

Yes. Active decay or gum disease must be treated before whitening can be considered. Whitening on unhealthy teeth can cause significant sensitivity and pain, and may mask underlying problems that need attention.
