The cost of teeth whitening in the UK on average ranges from around £250 to £800+, depending on the whitening system, dentist experience and level of whitening required. Home whitening systems prescribed by a dentist are often available from around £250–£450, while premium whitening treatments designed to achieve the lightest possible shade may cost £600–£800 or more.
One reason why the teeth whitening rate varies is that whitening systems have different treatment protocols. Some treatment plans involve whitening gradually over weeks, while others aim for dramatic shade improvements with longer lasting results.
When comparing teeth whitening costs, do not just compare the initial fee. Understanding these differences can help patients compare treatment options more accurately rather than focusing on price alone.
Different whitening systems follow different treatment protocols and can achieve different levels of shade improvement, which affects the overall cost.

You may feel slightly sensitive to hot or cold foods and drinks. Avoid strongly coloured foods and beverages during this period.
First Few Days
Many patients start noticing an increase in tooth brightness early during whitening. Any temporary sensitivity is generally manageable.

Depending on the whitening system used, results develop gradually throughout treatment. Most patients achieve last shade improvement during this period.

Top-up treatments and aftercare help maintain results.
The initial treatment fee is only part of the cost of teeth whitening. Some people choose to buy more whitening gel, replacement trays if they break, or even top-up treatments periodically to help maintain their results. The amount spent on maintenance largely depends on lifestyle habits, oral hygiene and how bright you want your smile to remain.
Often, yes. And if your old whitening trays still fit properly, you may need only more whitening gel for future treatment. Reusing existing trays may save money over a long-term teeth whitening process and may save you from purchasing new impressions or replacement trays.
Professional teeth whitening is a long-term investment rather than a quick fix. Results may last for years but teeth naturally absorb new staining from food, drink and lifestyle habits. Some people maintain their results with periodic top-up whitening rather than repeating the whole treatment, and future costs are often lower than the initial treatment fee.
Teeth whitening is considered cosmetic because it improves appearance rather than disease or function. It is therefore not normally provided by the NHS and is normally done privately. Most UK teeth whitening treatment is carried out in private dental practices under professional supervision.
No. Teeth whitening affects only natural tooth enamel. Existing crowns, veneers, bridges and tooth-coloured fillings will stay the same colour after treatment. Visible restorations may need to be replaced if they no longer match your newly whitened teeth. Consider this when evaluating the overall cost of professional teeth whitening.
