Crest white strips pro

Whitening strips use peroxide gel on the tooth surface; fit, concentration, wear time, gum contact, and existing dental problems affect their use.

The gel oxidises some stain molecules in enamel and dentine, while it cannot whiten fillings, crowns, veneers, or other restorations. Sensitivity and gum irritation can occur when peroxide reaches exposed dentine or soft tissue.

Read the product directions, place the strip only on clean tooth surfaces, and remove it at the stated time. Do not sleep in strips, overlap them onto inflamed gums, or use them over untreated decay, cracks, or strong sensitivity without a dental assessment.

Have a dentist examine persistent sensitivity, gum burning, uneven colour, darkening of one tooth, decay, or a broken restoration. Stop and seek advice if pain is significant or soft-tissue irritation does not settle.

Ask whether the stains are surface or internal, whether your enamel, gums, fillings, and crowns are suitable for whitening, and which peroxide method fits your needs. Ask how to manage sensitivity and match restorations after whitening.
