I have scratches and cuts on the inside of my lower lip; Some of them are getting worse. I was embarrassed to do so, but I asked my dentist about it and he said it was normal if you accidentally bite down on it, it can leave a permanent scare and there is nothing that you can do- that it looked perfectly normal. It really doesn’t feel normal and I haven’t found any useful suggestions on line (other than to use baking soda). I’m worried that its a serious issue. I’d appreciate any advice.
I cannot evaluate you or your lip, and do not have advice on this that would override the advice of a dentist who did look at your lip. If you remain concerned about this, I’d simply suggest seeking out a second opinion in person.
