The short answer
Crest Whitestrips use a peroxide gel to lighten stains on the enamel surface. The risks depend on the product strength, contact time, fit, existing tooth sensitivity, gum health, fillings, crowns, and how the strips are used.
How do whitening strips affect enamel and restorations?
Whitening strips are flexible plastic carriers coated with a peroxide gel, usually hydrogen peroxide or carbamide peroxide. The gel can pass through enamel to oxidize some stain molecules, but it does not whiten fillings, crowns, veneers, or other dental materials.
What should you do before and during strip whitening?
Read the package directions, keep gel off the gums, and stop if you develop marked pain, gum whitening, ulceration, or persistent sensitivity. A dentist can check for decay, cracks, exposed dentine, gum recession, and restorations before recommending a whitening method.
When should whitening with strips receive dental care?
Arrange dental care before whitening if you have toothache, untreated decay, bleeding or receding gums, cracks, or a loose restoration. Seek urgent care for facial swelling, fever, trouble swallowing, or trouble breathing.
What should you ask about whitening strips and sensitivity?
Ask which peroxide product and wear time fit your teeth, whether sensitivity or gum recession changes the plan, and whether visible fillings, crowns, or veneers will need a different cosmetic approach.
Frequently asked questions
Can strips whiten fillings?
No. Peroxide whitening affects natural tooth structure, not the colour of fillings, crowns, or veneers.
What if my teeth are sensitive?
Stop the product and arrange dental advice if sensitivity is strong, persistent, or associated with pain.
