How Much Does Teeth Whitening Cost in Barnet?

Professional teeth whitening in Barnet typically costs between £250 and £475, depending on the type of treatment and the practice. Barnet’s outer London location means pricing is generally more competitive than in central London. In-practice treatments sit at the higher end, while take-home kits from your dentist are more affordable.

Teeth whitening is not available on the NHS as it is considered a cosmetic treatment. For more on NHS dental access, see our NHS dentist London hub.

Types of Teeth Whitening Available

In-practice whitening uses a concentrated gel activated by a special light. Results are immediate, usually achieved in a single appointment lasting 60 to 90 minutes. Common brands include Zoom, Enlighten, and Beyond.

Take-home whitening kits involve custom-made trays and a lower-concentration gel that you wear for a set period each day, typically over two to three weeks. Results are gradual but long-lasting.

Combination treatments offer an in-practice session followed by a take-home kit for maintenance. Several Barnet practices offer this as a package.
