Whitening gel burned my gums: what should I do?
If whitening gel makes your gums sting, look white, or feel sore, stop using the product and do not add more gel or another whitening product. Keep the package and note which teeth and gum area were involved. A dental visit can check whether the irritation is likely related to product contact, tray fit, gum inflammation, or a different problem before any whitening plan continues.

Whitening gel burned my gums: stop rather than testing more
Stop the whitening product if your gums sting, turn white, feel sore, or develop a new irritated area. Do not use a longer application to see whether it settles, add a second product, or keep placing gel over the same spot. The American Dental Association lists temporary gum inflammation among the common adverse effects of whitening.
Keep the product package, tray, strip, or a clear photograph of the label. Note when you used it, how long it contacted the teeth, whether the product escaped from a tray, and whether the discomfort began immediately or later. Those details are more useful for a clinician than trying to judge the cause from a mirror alone.
Is this gum irritation, or is another dental problem involved?
Chemical contact can irritate gum tissue, but a sore or bleeding area can also be associated with plaque, calculus, gum disease, a sharp restoration edge, a poorly fitting appliance, or another local problem. An online guide cannot separate these possibilities. Do not cut or reshape a tray yourself to solve a painful spot.
Arrange prompt dental assessment if the area is worsening, very painful, swollen, bleeding heavily, associated with a loose or broken tooth, or accompanied by fever, facial swelling, or difficulty swallowing or breathing. Those symptoms should not be treated as a routine cosmetic-whitening reaction.
