I used a whitening strip, and i think the peroxide in it cut my gum. when i took it off i had a small white cut around my front tooth. the white is gone now but i still feel the cut. it is not that red just purple-ish. is it going to get infected? is it dangerous? should i put ice?
Hello, Thank you for consulting with Chat Doctor. No it is not dangerous as it is just a traumatic ulcer, which might have occurred because of trauma. Now it is in healing condition, it will take just 1 week. For pain, you can start with a topical anesthetic gel on. Hope it will help you.
