Tooth colour is genetically determined just like your hair. However teeth tend to darken with age and can become stained. Causes of tooth staining are commonly tea, coffee, red wine, some spicy foods and tobacco.
Most stains can be removed by a scale and polish which can be carried out by a dental surgeon, therapist or hygienist. A prophy jet which is similar to a jet washer with abrasives can also used.
Teeth whitening is a more thorough and lasting way to whiten teeth. There are essentially two methods that can be employed to whiten teeth, these are home whitening and in-surgery whitening or a combination of both.
Please see our leaflet whiter teeth for more information about all of these treatment options.
