How long does teeth whitening last

As you get older teeth often become discoloured due to changes in the mineral structure of the tooth. Obviously teeth also become stained by food, tobacco and wine. Some antibiotic medications (EG tetracycline) can lead to teeth stains or a reduction in the brilliance of the enamel.

The effects of teeth whitening can last for several months but may vary depending on your lifestyle - red wine, coffee, tea and tobacco can stain teeth.
