What is Teeth Whitening?
This is whitening process that lightens discolouration of enamel and dentine. It is the most popular cosmetic dentistry procedure.
Types of Teeth Whitening
There are two main types of whitening treatment available:
- ‘Zoom’ laser whitening – done in the dentist chair – takes approximately 90 minutes
- Home whitening – done in your own time at home – takes 1 hour per day (10-14 days)
There are many causes of teeth discolouration. The most common are ageing, consumption of tea, coffee, red wine and tobacco. Another cause of darkening of the teeth is nerve degeneration.
Who Would Benefit From Teeth Whitening?
Almost anyone can benefit, but you must remember that old fillings or porcelain crowns or veneers will not respond to the whitening process. A cosmetic dentist would be able to tell you if whitening would be an option for you.
How Does Teeth Whitening Work?
Both treatments use oxygen releasing whitening gel placed against the surface of your teeth. As oxygen enters the enamel and dentine, it whitens the coloured substances. Only the teeth colour is made lighter, while the structure of the teeth remains unchanged.
