Some people have visible fillings that are matched to the present shade of their teeth. Please note that whitening will not change the shade of these fillings to the new whiter shade of the teeth.
Similarly, crowns and bridges that blend aesthetically to stained teeth might stand out unfavourably after whitening.
Fillings, crowns, and bridges can be replaced after whitening to match the new shade of the teeth.
What is whitening
Tooth whitening is a bleaching process that lightens discolouration of the teeth to create a whiter, brighter appearance.
Who might benefit from tooth whitening
Almost anyone, although there are some cases where the treatment may not be effective. Whitening might not be appropriate for patients with very sensitive teeth or gums, extreme tetracycline stains, or other resistant intrinsic stains. Our dentists will examine your teeth to determine if you are a candidate for whitening.
What causes tooth discolouration
- Coffee, tea, cola
- Nerve degeneration
- Tetracycline (antibiotic) staining
- Excessive fluoride
- Genetic and acquired illness
is whitening safe
Yes! Research and clinical studies show that whitening teeth with carbamide peroxide under the supervision of a dentist is safe for the teeth and gums. Many dentists consider whitening the safest cosmetic procedure available today.
how does whitening work
Whitening gel is placed in a thin bleaching tray that fits over your teeth. The active ingredient, carbamide peroxide, converts to hydrogen peroxide. The hydrogen peroxide enters the enamel and dentin, bleaching the coloured parts of the teeth. The structure of the tooth is not changed; a lighter tooth colour is the only difference.
how long does whitening take
Results are usually seen after the first application. Maximum results generally occur when the process is continued for 10 to 14 nights. The degree of whiteness will vary from patient to patient, depending on the structure of the teeth, the number of applications, and the duration of treatment.
are there any side effects
Some people experience temporary tooth sensitivity to cold during the treatment. This can be avoided by using sensitivity toothpaste and usually disappears within one to three days
how long do the results last
The teeth will always be lighter than they once were but you might need a “touch-up” once or twice a year to maintain the whitest shade possible. To preserve the improvement it is best to avoid coffee, tea, red wine, and tobacco.
are there any reasons for not doing whitening
- If your teeth are very sensitive
- If there is root exposure
- If you are or think you might be pregnant
- If you are ill
