Understand your starting point
Surface stains and the natural colour of your teeth influence what whitening can achieve. Results vary from person to person.
Consider sensitivity
Some people experience temporary sensitivity during whitening. Discuss existing sensitivity with your dentist before you begin.
Know what will not change
Crowns, veneers and fillings do not whiten like natural teeth. Your dentist can explain how this affects the overall appearance of your smile.
This guide provides general information and does not replace an individual dental assessment. Speak with your dentist about your own needs.
