How much does teeth whitening cost in the UK?

What affects whitening costs

Professional in-chair whitening in the UK typically costs between £300 and £700 for a single session. This includes the consultation, the in-surgery treatment, and often an initial home maintenance kit. Prices vary by practice, location, and the light or laser system used.

Dentist-supervised home whitening with custom trays typically costs between £200 and £450. This includes taking impressions, making the custom trays, and providing an initial supply of whitening gel. Additional gel top-ups are usually available to purchase separately.

Over-the-counter whitening products range from a few pounds for whitening toothpaste to over £100 for more comprehensive strip or tray kits. These contain lower concentrations of whitening agent than prescription products and produce more modest results.

What is included in the quoted fee is as important as the headline price. A comprehensive whitening package should include an initial consultation, any pre-whitening preparation, the whitening treatment itself, custom trays where relevant, an initial gel supply, and at least one follow-up appointment. Some practices include a post-whitening sensitivity assessment.

Long-term cost depends on how often you top up. Home tray patients typically spend £20 to £60 per year on additional gel to maintain their result. In-chair patients who use a maintenance tray can extend results significantly without a full repeat treatment.

Teeth whitening is not available on the NHS as it is classified as a cosmetic treatment. All costs are private. Getting two or three quotes from GDC-registered providers is the most practical way to understand whether pricing is reasonable for your area.
