How often can i whiten my teeth with hydrogen peroxide

There is no universal schedule for peroxide whitening; frequency depends on product strength, contact time, tooth condition, and sensitivity.

Hydrogen peroxide whitens by oxidising coloured molecules in enamel and dentine. Repetition depends on the formulation, instructions, previous whitening, gum health, enamel condition, and sensitivity.

Use a product made for dental whitening exactly as labelled. Pause for sensitivity or gum irritation, and address decay, leaking restorations, or gum disease before repeating treatment.

See a dentist if sensitivity lasts, gums burn or peel, teeth develop patches, or colour changes unevenly.

Ask what concentration and contact time apply, when repetition could be considered, and how sensitivity changes the plan.
