Who needs tooth whitening?
Teeth may naturally be a yellowish or greyish colour and may darken as we get older. In addition teeth may stain from food and drink stains such as red wine and coffee or from cigarettes.
How does tooth whitening work?
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.
How long does whitening take?
You will usually see a difference after two to four weeks wear.
Will my crowns or bridges also be whitened?
Tooth whitening does not work on existing crowns and bridges. These are most often made from porcelain and unlike teeth are not susceptible to whitening. We can however discuss replacing your crowns or bridges if you are unhappy with their colour.
Is tooth whitening safe?
Studies have been carried out to show that tooth whitening by this method is very safe. The most common side effect is a temporary sensitivity of the teeth. If this happens we recommend that whitening is carried out every other night instead of every night.
How successful is tooth whitening and how long does it last?
Studies have shown that tooth whitening is 97% successful. After 3 years the whitening effect is unchanged in 74% of patients. However it is very simple to carry out further bleaching if necessary.
