Professional teeth whitening procedure
Professional whitening uses a peroxide gel under dental control to lighten stains after an oral examination.
The short answer
A professional teeth-whitening procedure uses a peroxide gel applied to the visible tooth surfaces, with the gums protected and the treatment monitored by a dental professional.

What is the direct answer?
What does this question mean?
Professional whitening is a cosmetic treatment for natural enamel and dentine that have become darker from food, drinks, tobacco, age, or certain medicines. It does not change the colour of fillings, crowns, veneers, or other restorations.
What can you do next?
A dentist first checks for cavities, gum inflammation, exposed root surfaces, cracks, and restorations, then records the starting shade. The procedure may involve gum barriers and several controlled applications of hydrogen peroxide or carbamide peroxide, followed by a shade check and advice about sensitivity.
When should you seek dental care?
Arrange an assessment before whitening if you have tooth pain, untreated decay, bleeding gums, enamel defects, or a restoration in the smile zone. Seek prompt care for facial swelling, severe pain, or a whitening reaction that persists after the product is removed.
What should you ask the dentist?
Ask which stains are likely to respond, whether any fillings or crowns will remain visibly different, what peroxide system will be used, and how existing sensitivity, gum recession, decay, or enamel wear changes the plan.
