Teeth Whitening in London

Professional teeth whitening is among the most sought-after cosmetic treatments at London dental practices. Whether you visit a clinic on Harley Street, in the City or in a local high-street practice in Clapham or Islington, you'll find options for both in-surgery whitening (delivering visible results within an hour) and take-home whitening kits with custom trays that work gradually over two to four weeks.

London dentists commonly use leading whitening systems such as Boutique Whitening, Enlighten and Zoom. These professional-grade treatments use peroxide-based gels to break down stains on the enamel, with results typically lasting six months to two years depending on your diet and how well you maintain your oral hygiene.

How Much Does Teeth Whitening Cost in London?

Professional teeth whitening in London generally costs between £250 and £800, often a little higher than the UK average given central London's premium clinics. In-surgery treatments using laser or LED light activation sit at the higher end of that range, while dentist-prescribed take-home kits usually start from around £250 to £400.

Teeth whitening is classed as a cosmetic procedure and is not available on the NHS. Under UK law, all whitening treatments must be carried out or prescribed by a registered dental professional. Avoid beauty salons or unregistered providers offering whitening — these are both illegal and potentially harmful to your teeth and gums.

What to Expect

Your dentist will first examine your teeth and gums to confirm they're healthy enough for whitening. A hygienist visit may be recommended beforehand to clear away surface staining and tartar buildup, which helps the whitening gel work more effectively.

Results depend on the natural colour of your teeth and the type of staining present. Most patients notice an improvement of several shades. Some temporary sensitivity during or after treatment is normal and usually subsides within a few days.
