Are whitening strips bad for your teeth
Whitening strips can cause temporary sensitivity or gum irritation because peroxide contacts enamel and may touch the gingiva.
The short answer
Whitening strips can cause temporary tooth sensitivity or gum irritation because peroxide contacts enamel and may touch the gingiva; risk depends on the product and oral condition.
What do whitening strips change and what do they not?
Peroxide oxidises stain molecules in natural enamel but does not change fillings, crowns, veneers, or bonding.
How can you reduce irritation when using whitening strips?
Follow directions, keep gel off the gums, and stop if discomfort becomes troublesome. A dentist can check for decay, cracks, exposed roots, gum disease, and restorations first.
When should sensitivity after whitening strips be assessed?
Seek care for persistent sensitivity, painful teeth, gum burns, or whitening over untreated decay.
How will whitening affect your existing dental restorations?
Will whitening match restorations, and how should sensitivity or irritation be managed?
