How to whiten my teeth without damaging them

Whiten teeth with a diagnosed, peroxide-based plan and gentle oral care rather than abrasive powders, acids, or excessive treatment.

Whitening changes the colour of natural enamel and dentine, while abrasion mainly removes surface material. Acidic mixtures can soften enamel, and aggressive scrubbing can wear enamel or expose dentine.

The same symptom can have different causes, so its location, timing, appearance, and associated signs guide diagnosis.

Have the teeth and gums examined first, use fluoride toothpaste and a soft brush, and follow the exact tray or in-clinic whitening instructions without extending treatment.

Keep the area clean and avoid products or techniques that irritate oral tissues.

See a dentist before whitening if you have sensitivity, cavities, erosion, cracks, recession, gum disease, or restorations in the visible smile.

A dentist can examine the tissues, test the tooth, and choose treatment based on the finding.

Ask what is causing the symptom, which examination or tests are needed, and what treatment addresses that cause.

Ask what can be done now and how to prevent the same problem from returning.
