What is teeth whitening?
Teeth whitening uses a peroxide-based gel to lighten the natural colour of enamel and dentine. Professional whitening is carried out after an examination so that decay, gum problems or leaking fillings are addressed first.
Whitening may be done in the clinic, at home with custom trays supplied by the dentist, or a combination — depending on what the clinic offers and what suits you.
Common reasons patients seek teeth whitening
- Yellowing from age
- Stains from tea, coffee or tobacco
- Preparing for a special occasion
- As part of a smile makeover before new crowns or veneers
Who may benefit?
- Adults with healthy teeth and gums
- Not generally recommended during pregnancy or breastfeeding
- Results are limited for some types of intrinsic staining; crowns and fillings do not whiten
Only a dental examination can confirm whether this treatment is right for you.
