The short answer
Professional tooth bleaching uses a peroxide gel to lighten stains on natural teeth after the dentist checks enamel, dentine, gums, decay, and existing restorations.
What is the direct answer?
What does this question mean?
The clinical treatment is tooth whitening, while “bleaching” refers to peroxide-based colour change. The gel diffuses through enamel and dentine and oxidises some stain compounds; it does not change the colour of most crowns, veneers, fillings, or bridges.
What can you do next?
A dental examination identifies decay, cracks, exposed roots, gum inflammation, tetracycline or trauma-related discolouration, and mismatched restorations. The dentist then selects in-office or prescribed take-home treatment, protects soft tissues, controls gel exposure, and reviews sensitivity.
When should you seek dental care?
Seek assessment before whitening if teeth hurt, gums bleed, a single tooth darkened, or there are untreated cavities. During treatment, stop for burning gums, significant sensitivity, swelling, or pain that persists.
What should you ask the dentist?
Ask which stains are likely to respond, how restorations will look afterward, which peroxide system is planned, and how sensitivity will be prevented and managed.

What determines the best next step?
