What is the direct answer?
Professional tooth whitening uses peroxide gel under controlled conditions, with the method chosen after checking enamel, gums, and existing restorations.
What does this question mean?
The clinical subject is professional bleaching of natural tooth enamel and dentine. A dentist first records shade, examines for decay and gum inflammation, protects soft tissues, applies the selected gel, and reviews sensitivity and colour before any repeat session.
What can you do next?
Bring details of previous whitening, sensitivity, fillings, crowns, and medicines. A dental team can clean external deposits first, select tray or in-office treatment, and give written instructions for gel quantity and contact time.
When should you seek dental care?
Book an examination before treatment if you have untreated decay, gum bleeding, exposed roots, enamel erosion, or unexplained toothache. These findings can make whitening painful or mask a problem.
What should you ask the dentist?
Ask which peroxide is used, how the gums will be protected, whether restorations will change colour, and what happens if the shade is uneven. Ask for a plan based on your tooth condition, not just a product name.
