Why whiten teeth?
While everyone dreams of a Hollywood smile, very few people have naturally bright, white teeth. Your teeth change colour as you get older, and other factors like what you eat and drink can affect their colour. Coffee, red wine, curry, balsamic vinegar and dark berries are all teeth staining culprits. You may have an important event coming up, such as a wedding or holiday, that you want to look your best for. It may be that your teeth have gradually become discoloured due to certain prescribed medications or antibiotics. A build up of calculus (tartar) can also lead to yellow-looking teeth, as can habits like smoking.
