Why whiten teeth?
Whitening the teeth brightens the enamel and dentine. It uses a casted mould and a hydrogen-peroxide based gel. If carried out under proper conditions and under the control of a dental surgeon, it is not toxic or harmful to dental health.
Various factors are involved in dental discoloration:
- It can be hereditary: natural coloration or aging of the teeth.
- Pathological cause: taking drugs while teeth are forming can cause dischromia.
- Lifestyle: coffee, tea, tobacco, wine, tannins, etc.
No dental whitening should be carried out without a prior oral-dental examination and report by the dentist, to make sure that there are no contraindications (untreated cavities, weak enamel, gingival irritation, etc.).
The various dental whitening techniques
If the dental whitening treatment can be performed at the dentist’s office by a technique known as a “chair” procedure, it is generally then completed on an outpatient basis at your home.
Outpatient dental whitening:
This treatment starts at the dentist’s office with a cast made of your teeth and continues at home using a hydrogen-peroxide gel.
"Chair” dental whitening:
This requires two or three visits to the dentist of about 30 to 60 minutes each.
