How does tooth whitening work?

Smile better.

Most of us enjoy drinking tea, coffee and the odd glass of red wine, causing our teeth to become gradually discoloured, so it’s no surprise that tooth whitening has become one of the most popular aesthetic treatments around.

But how does tooth whitening work? Does it hurt or damage your teeth? And will you like the results? After all, celebrities whose teeth are a dazzling – and frankly implausible – shade of white has become an all-too-common sight.

Tooth whitening is actually a great way of subtly improving the appearance of your teeth, restoring a lighter, whiter look and making you feel more confident and keen to show off your smile. But it needs to be carried out in the right way.

With this in mind, leading a healthy lifestyle is as much a part of keeping your mouth and teeth healthy as keeping a good daily routine with brushing and flossing.

The process of tooth whitening at your dentist is quick and painless, and will usually consist of a couple of visits followed by some at-home treatment.

•    They’ll take impressions of your teeth (which just takes a couple of minutes) in order to create your personalised whitening trays 
•    You’ll return a week or two later to collect your trays. Your dentist will check they fit correctly and demonstrate how to use them
•    The dentist may perform one session of whitening in the salon, after which your teeth will already appear lighter
•    You’ll wear the trays at home every day or every other day for a few hours or overnight

The beauty of at-home treatment is that you can control how white you want your teeth to be, and you can also use the trays for a monthly ‘top-up’ treatment to maintain your lovely new, whiter smile.
