How much does teeth whitening cost in Merton?

Professional teeth whitening in London typically costs between £300 and £450 for a course of treatment. Take-home kits with custom-made trays tend to sit at the lower end, while in-practice (laser or light-activated) whitening and combined options cost more. By law, teeth whitening can only be carried out or prescribed by a registered dental professional, so it is worth being wary of cheaper high-street or salon offers. Whitening is purely cosmetic and is not available on the NHS. For a fuller overview, see our Teeth Whitening in London hub.

Teeth whitening in Merton: frequently asked questions

How many dentists in Merton offer teeth whitening?

29 of the 44 CQC-registered dental practices in Merton name teeth whitening on their own website. They are all listed on this page; we verify treatments from each practice's own site rather than guessing from directory categories.

Is teeth whitening available on the NHS?

No. Whitening is a cosmetic treatment, so you pay for it privately. In the UK, only a registered dental professional can whiten teeth with professional-strength gel. Avoid whitening offered by salons or beauty businesses.

How long does teeth whitening last?

The NHS says the effect may last around 3 years. Coffee, tea, red wine and smoking make teeth stain again sooner. Using your home trays now and then can top up the colour.
