Tooth whitening works by applying a bleach based whitening gel to the teeth. Firstly we will take impressions of your mouth and make a small plastic mouth guard which fits over your teeth. This is specially made in a laboratory to fit your mouth exactly.

We will then fit the tray and give you some special whitening gel. We will also take recordings of the shade of your teeth so that we can monitor the changes. We will then show you how to apply the gel to your teeth using the tray. The tray is very small and light and is usually worn every night.
