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.
How much can these whitening strips change tooth colour?
Whitening strips may lighten some natural tooth colour, but results depend on the formula, wear instructions, starting shade, stains, and restorations.
How does peroxide reach the front tooth surfaces?
Strips hold peroxide-containing material against front tooth surfaces. They do not bleach crowns, fillings, or veneers.
How should you follow the whitening instructions?
Follow the label and do not extend wear time. Stop for gum irritation or sharp sensitivity and compare photographs under consistent conditions.
Which dental issues should be assessed before whitening?
Have cavities, cracks, recession, or a dark single tooth assessed before whitening. Persistent pain, burns, or swelling needs care.
What should you ask about banding, restorations and sensitivity?
Ask whether the product suits your enamel and gums, whether a restoration may mismatch, and what explains banding or sensitivity.
