Teeth Whitening: Options and Considerations

What can whitening change?

Whitening products are intended to lighten the colour of natural teeth. They do not change the colour of crowns, veneers, or fillings. Surface stains, natural tooth colour, and the cause of discolouration affect the result. An examination helps distinguish a cosmetic concern from a tooth that needs treatment.

Who should be checked first?

Tell the dentist about sensitivity, cavities, gum problems, exposed roots, or a single tooth that has darkened. Those issues may need attention before whitening. The dentist can explain whether whitening is likely to address your concern and whether a different option would be more appropriate.

What options might be discussed?

Professional whitening may use an in-office method, take-home trays, or another protocol, depending on what the clinic actually provides. Ask which method is proposed, how to use it safely, what changes are realistic, and how existing restorations may appear afterward. Do not use more product or leave it on longer than instructed.

Sensitivity and maintaining the result

Temporary sensitivity or gum irritation can occur. Tell the dental team if you have had these problems before. Colour change and how long it lasts vary with the person, habits, and method. Ask whether future touch-ups would be needed and what they would involve. The cosmetic care service page is the clinic-specific destination for whitening enquiries.

Frequently asked questions

Will whitening change a crown?
No. Restorations generally keep their existing shade.
Can whitening fix one dark tooth?
That depends on the cause. A dentist should assess a single discoloured tooth.
Is sensitivity normal?
It can happen; ask the clinician how to manage it and when to stop treatment.
