Teeth yellowed by tea, coffee or age?
Teeth whitening
Professional whitening lightens the natural colour of teeth safely under the dentist's supervision. Fillings, crowns and veneers don't change colour, so they are checked first.
When it's needed
- Teeth darkened by tea, coffee, tobacco or age
- Before a wedding or special occasion
What to expect
- Check-up and cleaning first
- Gums are protected
- Whitening gel is applied in the clinic, or trays are made for use at home
- Shade is compared before and after
Afterwards
- Sensitivity for a day or two is common
- Avoid strongly coloured food and drinks for 48 hours
- Results fade slowly; touch-ups can help
Common questions
Is whitening safe?
Done or supervised by a dentist, yes. Over-the-counter products used too often can harm the gums and enamel.
