Do whitestrips damage enamel
Whitening strips can cause temporary sensitivity or gum irritation, but correct use of a suitable product should be based on the strip’s peroxide form
The short answer
Whitening strips can cause temporary sensitivity or gum irritation, but correct use of a suitable product should be based on the strip’s peroxide formulation and the condition of your teeth and gums.
How do whitening strips place peroxide against enamel?
Whitestrips place a peroxide gel against enamel. The gel passes through enamel and dentin to react with stain molecules; irritation is more likely when strips contact the gingiva, are used too often, or are placed over decay, cracks, exposed roots, or inflamed gums.
How should you use whitening strips safely at home?
Read the product directions, keep the gel on the teeth rather than the gums, and do not extend the contact time or combine whitening products without advice. Stop and arrange an examination if sensitivity is strong, pain persists, or the gums become white, sore, or ulcerated.
When should a dentist assess your teeth before strips?
See a dentist before using strips if you have untreated cavities, enamel defects, gum recession, restorations on visible teeth, or a single dark tooth. Persistent sensitivity after stopping also needs assessment.
What should you ask about whitening strength and sensitivity?
Ask which product concentration is appropriate, whether your enamel and gums are healthy enough, how restorations will look afterward, and what to do if sensitivity develops.
