I recently got into this horrible habit of biting my cheeks. It all began when I bit my cheek by accident when I was eating, and then I would bite of the rough bits and it became a habit. The inside of my mouth was pretty chewed up for a while- how gross. I suppose its a similar habit to biting your nails - you always HAVE to bite off that nick or rough bit thats catching, except that has no consequences. Anyway I have recently made myslef stop but now I have small dark spots on my cheeks. Could it be cancer? Is it even possible to get cancer this way - through constant regeneration of tissue? I am hoping it is burst blood vessels! Please help!

Hello cheekbiter

The spots are most likely blood blisters. I have not come across a case or heard of a mouth cancer caused by a cheekbiting habit, so that must be rare. Follow the advice I have given on using the 'splint of air' to stop bruxism/clenching. It will help stop the cheekbiting too. I would give your cheeks a couple more weeks before seeing your dentist if they don't go away.

Last week I remember accidentally biting my cheek very hard. For the past week when I have been eating I'll bite the same spot because it is "swollen", or enlarged. I didn't think anything of it until today when I decided to look at why it was "bulging" out so much.

I took out a mirror and found I had three almost blackish/blue-ish spots in that area and the texture can be described as being a very thick tissue.

So now I'm wondering whether these are merely blood blisters that are swelling from me continuing to accidentally bite on my cheek, or if they developed beforehand and were actually responsible for the first time I bit down on my cheek.

I'm really concerned.

I'm 21 female, never smoked, don't drink, occasionally suntan (if that matters). What is the likelihood I have some kind of a mouth cancer or melanoma in my mouth??

Thank you!! I'm very scared...

Hello concernedcheek

It is not possible to make a diagnosis over the Internet but they are more likely to be blood blisters in view of the history given. They should disappear in about two weeks. If still there after that or concerned, please see your doctor. Do let us know how you get on.
