My friend has bump on the inside of his mouth. Directly on his cheek. He bites his cheek a lot but he's worried that it may be from his girlfriend? Can you tell whether it's from the biting of his cheek or from his girlfriend?

Well, did she bite his cheek? Or are you asking if she has cooties?

It's almost certainly from him biting his own cheek. That often leaves permanent scars. Lots of people have them.

What do you mean "from his girlfriend"?

Anyone who is online can you try and answer the question as soon as possible thank you

I don't understand the question

Like he's been kissing his girlfriend but she says she had never had a bump on the inside of her mouth but he says she the only one he has been kissing

Im asking is there a possibility she could have passed something on to him?

It's from him biting the inside of his cheek.

Thank you so much... he has really been stressing over it because he doesn't know what to do... do you have any suggestions?

He should try to stop biting his cheek. It's a nervous habit - like biting your nails. He needs to make an effort to stop.

OK... ill be sure to tell him that thank you all so much!

Its from bitting I use to do it and now I have like an inside scar I went to check it out and its nothing just like getting cut on your skin its all good
