"In as little as 45 minutes, your teeth can be dramatically whiter."
Time, smoking, tea and coffee are just a few of the things that cause your teeth to yellow and discolour. Whitening is a bit like a facial in that it helps to unlock pores in your tooth so that stains are gently removed leaving teeth cleaner and brighter.
Whiter teeth can take years off your appearance and the effects can last up to ten years depending on whether or not you smoke or how much tea, coffee or red wine you drink.
Although teeth themselves whiten well, any fillings or crowns will remain the same colour and may need replacing to match the new lighter colour of your teeth.
All whitening products are based on a hydrogen peroxide solution: the only difference in the hundreds of systems out there is the concentration of the solution and the way it is applied to your teeth.
