Tooth and gum sensitivity appears in many reviews, especially with higher peroxide formulas. Dentists often advise using a sensitive toothpaste and avoiding very hot or cold foods right after a session.
People with crowns, fillings, or braces are generally advised to consult a dentist first, as strips may not adhere evenly or could irritate gums in these areas.

FAQ
Reader questions
Do Crest whitening strips damage enamel? Most user reviews and dental guidance indicate that Crest whitening strips are safe for enamel when used as directed. Occasional mild sensitivity is reported, but long-term enamel damage is rare in people with healthy teeth. How long do the results last after using the strips?
Users typically see results last several months with normal eating and drinking habits. Touch-up sessions every few months help maintain brightness, especially if staining foods and beverages are consumed frequently.
Can I use these strips with braces or dental work?
People with braces, veneers, or crowns are often advised to avoid whitening strips or to seek specific instructions from their dentist, as uneven coverage and gum irritation can occur around fixed dental work.
Why do some people get more sensitivity than others?
Individual differences in enamel thickness, gum health, and previous whitening treatments can influence sensitivity. Using a lower peroxide formula and shorter session times may reduce discomfort for sensitive users.
