There is no single whitening method that suits everyone. Results vary with the type of staining, the natural colour of your teeth and how well you maintain them.
Whitening toothpastes
These mainly remove surface stains through mild abrasion and do not change the natural colour of the tooth much.
Over-the-counter kits
Strips and gels contain low concentrations of peroxide. Change is gradual and fit can be an issue.
Take-home trays from your dentist
Custom trays with a prescribed gel, worn for a set period after an examination. This allows gradual, controlled change.
In-chair whitening
A stronger gel applied at the practice with the gums protected, usually in one appointment. Some people are advised to follow up with take-home trays.
Keeping results
Whitening is not permanent. Tea, coffee, red wine and smoking will re-stain teeth over time, and touch-ups may be needed. Regular check-ups and cleans help.
Side effects
Sensitivity and gum irritation are common with all methods and usually settle within a few days.
