whats going on with it? like usually to get rid of the pain l just bite it off is it bad for you tho?! well im just curious wats wrong with it...so...yea haha

l think what you have is a Canker sore, if you've been having a lot of sugary and unhealthy foods (such as candy or sugary soda and such), you can get them on your tongue or other areas in your mouth, they hurt a lot, but after a few days (of eating a bit better) they will go away.
l think if you try biting them off, that is really not good for you. If you think about it, it is sorta like biting away part of your tongue.

Hopefully l made some sense. =P

its not a canker sore l tell you that its a dead taste bud it will fall off in a week or 2 l had them they hurt do not bite them of tried it made the pain is worse plus you will be bleeding and it will hurt more
