About this topic
What does whitening change?
An application for reducing some stains on natural teeth, after an oral-health review.
Which stains are assessed?
For external stains or age-related shade changes, oral health is checked before whitening is considered.
Before whitening
The cause of staining, fillings and crowns, gum condition and sensitivity history are reviewed.
Assessment and application

- Reviewing the source of staining and restorations
- Explaining the suitable method and achievable change
- Discussing sensitivity and care
Sensitivity and care
Temporary sensitivity can occur. Following personal guidance and reviewing habits that increase staining may help.

Frequently asked questions
Does whitening change the colour of fillings?
Whitening affects natural tooth tissue; fillings and crowns may not change in the same way.
