What is tooth whitening?
Tooth whitening can be a highly effective way of lightening the usual 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 whitening?
There are a number of reasons why you may 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 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.
