Does uv whitening damage teeth

UV whitening risks depend on the peroxide gel, light exposure, and existing tooth disease; sensitivity and gum irritation are possible.

Whitening light is used with a peroxide gel that changes stain molecules in tooth structure. It cannot whiten fillings or crowns, and exposed dentine, cracks, decay, or gum recession can make the procedure more uncomfortable.

Ask for an examination before treatment so decay, gum inflammation, cracks, and leaking restorations can be managed first. The clinician can protect the gums, adjust gel exposure, and stop if pain develops.

Seek assessment for persistent pain, one-tooth pain, gum burns, or sensitivity that does not settle after whitening. Do not continue cosmetic treatment while untreated disease is present.

Ask which gel and light are used, how your gums will be isolated, and whether fillings or crowns will match afterward. Ask how existing sensitivity changes the treatment plan.
