Can Botox Stop Lip Biting?

Biting down is due to the functional activities of the masseter muscles ( chewing muscles) , it require coordinated and balanced contraction of a group of muscles to bring the lower jaw upward to the upper jaw and normally is done unconciously. Lip biting happens when lip(s) are caught between teeth. Lip movements are necessary to avoid getting caught . Injection of botox to paralize lip muscles would worsen your problem and it is ill-advised. You may consider cousulting with an oral surgeon for a thorough examination.  

Please don't do this. It's just not a good idea. Injecting Botox like this will do a variety of things, all of which are bad: you won't be able to talk or form your mouth correctly to speak, you can't use a straw, you may not be able to eat or close your mouth, you won't be able to smile, etc. All of these are far worse than a callous in the mouth. This is not a good idea that will result in far more embarrassing consequences!
