Teeth whitening can be a simple and quick way to refresh your smile. It’s one of the most popular cosmetic dental procedures and the results can be quite dramatic. An hour in a dental chair can transform stained or discoloured teeth into a whiter smile.
Likewise, a whitening kit recommended by your dentist may allow you to lighten your teeth in the comfort of your own home.
Causes of discoloured teeth
There are various reasons why teeth become discoloured. Some people are simply born with yellowish teeth while, for others, their teeth yellow as they age.
The biggest cause of stained teeth is due to what is put in the mouth. Smoking, coffee, tea and red wine can all colour the teeth. And, of course, the more you partake, the worse the staining will be. Dark foods such as beetroot, cherries and mulberries can also stain the teeth.
Finally, various medications may also make the teeth look yellow and stained. Fortunately, teeth whitening treatments work effectively on the vast majority of people.
