Check suitability first

Your dentist should assess your teeth and gums before whitening. Existing restorations, such as crowns and veneers, do not lighten in the same way as natural teeth.

Talk about sensitivity

Whitening can cause sensitivity or gum irritation. Discuss these possibilities, what your clinician recommends and who to contact if you have concerns during treatment.

Set realistic expectations

Results and treatment times vary. Ask how your proposed approach works, how it is supervised and what aftercare is involved. Avoid products or promises that bypass an appropriate dental assessment.

Make your consultation count.

A useful appointment ends with a plan you understand. Bring your questions, ask for explanations in plain language and check what happens after the visit. You should know who will provide your care, how to raise a concern and what the next appointment is intended to achieve. If you are unsure about a recommendation, take time to ask about alternatives before deciding.
