Crest 3d whitening professional effects

Whitening strips use peroxide to lighten natural tooth stains, with results shaped by the product, contact time and the original discoloration.

The strip holds a peroxide gel against the front surfaces of teeth. The gel can break down some molecules responsible for discoloration, but it does not recolor fillings, crowns, veneers or other restorations.

Read the product directions, keep gel away from the gums, and do not extend contact time to chase a faster result. Have a dentist check pain, cavities, gum recession, cracks or mismatched restorations before whitening.

Seek care before use if a tooth is painful or dark after trauma, and stop if intense sensitivity or gum burning develops. Uneven color after treatment may require assessment rather than repeated applications.

Ask whether the discoloration is surface stain, internal tooth discoloration or a restoration mismatch. Ask whether a fitted tray or clinic whitening better controls gel contact for your teeth.
