Change tooth colour

Teeth whitening

Dental whitening uses bleaching material to lighten natural teeth. A dentist must first assess whether it is suitable and explain the likely limitations.

General information only. A dentist needs to examine you before advising whether a treatment is suitable.

In plain language

What it is

Dentist-supervised home whitening commonly uses custom trays and prescribed gel. The exact product and schedule must come from the treating clinician.

Read a little more

Whitening does not change the colour of fillings, crowns, veneers or dentures. Existing restorations may therefore look different after natural teeth lighten.

Assess

The dentist checks oral health, discusses the cause of discolouration and considers existing restorations.

Prescribe

If suitable, the clinician explains the approved system, how to use it and when to stop or seek advice.

Review

Response and sensitivity can be reviewed. Results vary and maintenance may be discussed.
