Laser teeth whitening is one of the most popular and requested cosmetic dental treatments available today. This treatment provides almost immediate whitening of the teeth which can be achieved in a one hour power tooth whitening session with a cosmetic dentist. Laser teeth whitening is a process whereby a ‘whitening gel’ is used to change the colour of discoloured teeth; the whitening gel works by penetrating the enamel of the teeth and oxidising the stains which have caused the tooth discolouration.

The tooth whitening process lightens and brightens teeth and gives you a healthier looking and whiter smile.

Tooth staining can occur for a number of reasons, some of which include natural ageing of the teeth, smoking, drinking and dietary intake of staining foods.

Many different types of food and drink, for example red wine, tea, coffee and curries can cause stained teeth.

The procedure for laser teeth whitening involves the cosmetic dentist protecting your gums and lips before commencing the tooth whitening process. The whitening gel is applied to your teeth and the laser is utilised by the cosmetic dentist to activate the crystals in the peroxide based whitening gel. As the gel crosses the patient’s tooth enamel, it is activated and this in turn lightens the colour of the teeth by the process of oxidation.

The laser tooth whitening process is repeated several times in a session, depending on the severity of staining on the teeth.

Laser teeth whitening is ideal for people who want to transform their teeth and smile with minimal invasive treatment, at a reasonable cost and within a short period of time.
There is no drilling of the teeth involved in the process, so the procedure is comparatively straightforward, with minimal side effects and downtime.

Providing you follow a good aftercare programme, the results of this cosmetic dentistry procedure should last for up to two years.
