What is tooth whitening?
Tooth whitening can be a very effective way of lightening the natural colour of your teeth without removing any of the tooth surfaces. 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.
How long will my teeth stay white?
The effects of whitening are thought to last up to three years. However, this will vary from person to person. The effect is less likely to last as long if you smoke, eat or drink products that can stain your teeth. Ask your dental team for their opinion before you start the treatment.
