Many people do not have perfectly white teeth: coffee, tea, red wine, some foods, and smoking all stain them and teeth naturally tend to become discoloured as we age. If you want to restore them to a lighter shade and brighten up your smile, tooth whitening is the simplest way to achieve it.
Whitening will remove discolouration that has built up within your teeth and restore them to your natural shade, rather than making your teeth unnaturally white. What it can’t do is restore the colour of teeth that have been damaged or are dead after root canal treatment (but we can offer you veneers for such teeth if you need them).
If you already have crowns or veneers they will not whiten like your natural teeth. If you are planning to get them, it would be sensible to have your teeth whitened before your tooth-colour is matched for the crown or veneers. We will discuss your options with you before you start.
