Teeth whitening can be a very effective way of lightening the natural colour of your teeth without removing any of the tooth surface. It cannot make a complete colour change, but it may lighten the existing shade.
Why would I need my teeth whitened?
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 by 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 your teeth. Some people may have staining under the surface, which can be caused by certain antibiotics or by tiny cracks in the teeth which take up stains.
What does tooth whitening involve?
Professional bleaching is the most usual method of tooth whitening. Your dental team will be able to tell you if you are suitable for the treatment, and will supervise it if you are.

They will then apply the whitening product to your teeth, using a specially made tray which fits into your mouth like a .

What about home whitening kits?
There are many home whitening kits available, including paint-on whiteners and strips. How effective these are
depends on the amount of whitening agent they contain.
Home kits are cheaper but they are not always assessed for safety and tend to be more acidic. So there is a chance that these products could damage your teeth and gums. Because tooth whitening is a complicated procedure we advise that you always talk to your dentist before starting the treatment.
How safe are beauty kiosks and beauticians?
In Europe and in some other countries whitening can only legally be carried out by a dentist. So tooth whitening by
beauticians and in whitening kiosks is illegal. In Europe, it is illegal to supply bleaching material containing more than 0.1% peroxide (or the equivalent in carbamide peroxide) to anyone other than a dentist, or direct to the public.
These regulations are to protect the public. They make sure that anyone carrying out whitening is properly trained and has the right skills and knowledge to carry out the procedure without risking permanent damage to the teeth or gums.
