Does teeth whitening weaken teeth
Whitening changes colored molecules in enamel and dentin rather than filing away tooth structure, but misuse can cause sensitivity or gum irritation.
Can whitening weaken teeth or only change their colour?
Whitening changes colored molecules in enamel and dentin rather than filing away tooth structure, but misuse can cause sensitivity or gum irritation.
How does peroxide affect enamel and dentin?
Peroxide molecules diffuse through enamel and dentin and oxidize discoloring compounds. Cavities, cracks, erosion, recession, and exposed dentin can increase sensitivity.
How can whitening be planned safely for your teeth?
Have teeth and gums checked first, then use the prescribed concentration and contact time and stop if sharp sensitivity or chemical irritation occurs.
When should whitening symptoms be checked by a dentist?
Seek care before whitening with pain or decay, and afterward for persistent sensitivity, sore white gums, or an uneven result.
What whitening method suits your teeth and restorations?
Ask whether the stain is surface or internal and which method fits your enamel, gums, and restorations.
