Whitening lightens the natural shade of teeth using a professional-strength product, either applied in the practice or in custom trays you use at home.
No. It lightens natural tooth structure, so results vary with the starting shade and the cause of discolouration. It does not change the colour of crowns, veneers or fillings.
Temporary sensitivity is common during and shortly after treatment and usually settles. Tell your dentist if you already have sensitive teeth.
Professional treatment starts with checking that your teeth and gums are healthy, and uses trays made to fit your mouth so the product stays where it should.
It fades gradually, and how fast depends on diet and habits. Coffee, tea, red wine and smoking all shorten it.
A cosmetic treatment, done properly.
