Crest 3d vivid white strips before and after

Whitening strips may lighten some natural tooth colour, but results depend on the formula, wear instructions, starting shade, stains, and restorations.

Strips hold peroxide-containing material against front tooth surfaces. They do not bleach crowns, fillings, or veneers.

Follow the label and do not extend wear time. Stop for gum irritation or sharp sensitivity and compare photographs under consistent conditions.

Have cavities, cracks, recession, or a dark single tooth assessed before whitening. Persistent pain, burns, or swelling needs care.

Ask whether the product suits your enamel and gums, whether a restoration may mismatch, and what explains banding or sensitivity.
