| Tell me about tooth whiteners |
Tooth discolouration may be intrinsic - the teeth simply developed with discolouration - or extrinsic - the teeth were stained by coffee or foods, for example. Talk to your dentist if you are worried about the colour of some of your teeth.
If teeth are discoloured, then it may be possible to lighten them by applying tooth whiteners, using a tray which is fitted to the shape of your mouth. The dentist takes an impression of your teeth to make the tray and whitener is then put in the tray beside the teeth which are to be treated. Whiteners normally use hydrogen peroxide (in the form of carbamide peroxide, or urea peroxide).
Superficial staining is generally easier to deal with than intrinsic staining but techniques now in common use in dental practice can help with most forms of tooth discolouration.
