Teeth can darken with age or due to factors such as tea, coffee and smoking. Teeth whitening is the lightening of tooth colour using gels applied under the supervision of a dentist.
Methods
- In-clinic whitening: Carried out in the surgery, with the gums protected.
- Home whitening: Carried out under the dentist's supervision, using custom-made trays and a gel provided by the dentist.
What you should know
- Decay and gum problems need to be treated before whitening.
- Fillings, crowns and veneers do not change colour with whitening.
- Temporary sensitivity may occur after the procedure.
- How long the result lasts depends on diet and oral hygiene habits.
