Teeth whitening is the most searched-for dental treatment in London, and for good reason – it’s one of the quickest and most affordable ways to improve your smile. But prices, methods, and results vary enormously depending on where you go and what type of whitening you choose.
What Is Professional Teeth Whitening?
Professional whitening uses higher-concentration bleaching agents than over-the-counter products, applied or supervised by a dentist. It’s the only form of teeth whitening that’s legal in the UK when performed by someone other than yourself – beauty salons offering whitening are technically breaking the law.
The most common professional options are in-surgery whitening such as Zoom or laser whitening, which takes about an hour and costs more; and at-home whitening kits provided by your dentist with custom-fitted trays, which takes one to two weeks and is usually cheaper.
How Much Does Teeth Whitening Cost in London?
Professional teeth whitening in London typically costs between £250 and £700. In-surgery treatments like Zoom or Enlighten tend to sit at the higher end. Dentist-provided home kits usually cost £250-£400. Costs vary by borough – expect to pay more in central London than in outer boroughs. For a full breakdown, see our London dental cost guide.
Teeth whitening is not available on the NHS as it’s considered cosmetic treatment. For information on what is covered, see our NHS dentist London hub.
How Long Does It Last?
Results typically last 6 to 12 months depending on your diet and habits. Coffee, tea, red wine, and smoking all accelerate staining. Most dentists recommend occasional top-up treatments to maintain results.
