Has anyone ever gotten mouth sores from chewing Nicorette gum?

Recently I frequently had tingly tongue and mouth swelling. (once a month, each time last for 5-7 days. ) I believe it is cause by long time chewing the nicotine gum. After chewing for 2-3 years and recently symptoms are quite frequent. I have to quit everything now. First I thought was germ infection by sharing the toothpaste or got it from food allergy but I realize after eliminate all the possible factors and I still got it recently. Then I realize that nicotine might already done some damage. I think my mouth actually got thinner or the layer of protection has been destroyed by nicotine. You all better quit it, it is a bad stuff! they don’t warn the users enough. Quit smoking and relies on this is not the solution. Seek God, seek help. God bless you!

Yes, it gives me painful annoying tongue sores. Thinking about switching to the patch or just quitting altogether.

Mouth sores are well known as a side effect--it seems to get better with time--try to cut down when you have sores--I've been chewing for 6 years and can't get off--it is very expensive--I've lost several teeth, but no one knows for sure if that's related. Nicotine does constrict blood vessels and is not good for the gums or heart. There is not a lot of information out there.

Although mouth sores is not a known side effect of Nicorette gum, it is highly likely to be the cause. Or if not the cause then it may have aggravated the condition ... if you got a small one, chewing gum must have made it bad or worse. The best thing would be to stop chewing gum and let the sores/ulcers heal and then use gum again if you really want .l..but if you can give it up after that then it'll be great.
