Does peroxide make your teeth white
Peroxide can lighten some tooth stains, but its concentration, contact time, and effect on teeth and gums matter.
The short answer
Peroxide can lighten some tooth stains by oxidizing color molecules, but concentration, contact time, tooth condition, and gum protection control the result.
How does peroxide lighten some tooth stains?
Hydrogen peroxide and carbamide peroxide release oxygen that breaks down some colored compounds in enamel and dentin. They do not remove tartar, repair cavities, or reliably change the color of crowns, veneers, fillings, or bonding.
What should you do before using peroxide to whiten?
Use only a dental product according to its instructions, and stop if you develop significant sensitivity or gum irritation. Do not swallow peroxide or use concentrated household products in the mouth, because the tissue response depends on concentration and exposure.
When should a dentist check your teeth before whitening?
Have a dental examination before whitening if you have pain, cavities, gum inflammation, enamel defects, or extensive restorations. Seek care for chemical burns, persistent sensitivity, or uneven color after use.
What should you ask about peroxide whitening results?
Ask which peroxide formulation and delivery method suit your teeth, whether existing restorations will match afterward, and how sensitivity or gum contact will be managed.
