Tooth Whitening

Tooth whitening can be a highly effective way of lightening the natural colour of your teeth without removing any of the tooth surface.

There are a number of reasons why you might get your teeth whitened. Everyone is different; and just as our hair and skin colour vary, so do our teeth. Very few people have brilliant-white teeth, and our teeth can also become more discoloured as we get older.

Your teeth can also be stained on the surface through food and drinks such as tea, coffee, red wine and blackcurrant. Smoking can also stain teeth.

Calculus or tartar can also affect the colour of teeth. Some people may have staining under the surface, which can be caused by certain antibiotics or tiny cracks in the teeth which take up stains.

There is now laser whitening or ‘power whitening’. During this procedure a rubber dam is put over your teeth to protect the gums, and a bleaching product is painted onto your teeth. Then a light or laser is shone on the teeth to activate the chemical. The light speeds up the chemical reaction of the whitening product and the colour change can be achieved more quickly using this procedure. Laser whitening can make teeth up to five or six shades lighter.

The other procedure is called professional bleaching which is the most common form of tooth whitening. Your dentist will be able to tell you if you are suitable for the treatment, and will supervise it if you are. First the dentist will put a rubber shield or a gel on your gums to protect the soft tissue. They will then apply the whitening product to your teeth, using a specially made tray which fits into your mouth like a gum-shield.

The ‘active ingredient’ in the product is usually hydrogen peroxide or carbamide peroxide. As the active ingredient is broken down, oxygen gets into the enamel on the teeth and the tooth colour is made lighter.
