How much does teeth whitening cost in Harrow?

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.
