I have been biting my tongue and inside of my left cheek.  This is involuntary and only happens when I talk.My tongue goes to the left and then the biting occurs.  A CT Scan and MRI of the brain and both were clear.My dentist, primary care physician and neurologist think it is neurological but nothing shows up on the CT Scan nor the MRI.
Hello, As per your query, you have symptoms of cheek bite which seems to be due to improper dentition, increased stress levels and odd chewing habits. This occurs very commonly. Need not worry about it. I would suggest you to visit oral and maxillofacial surgeon once and get it examined and start treatment as per cause. When dentition have excess gaps or very less gap than it causes flap of cheek to come in between the teeth, so dentition needs to be corrected in that case. Chat Doctor.  Chew on sugar-free gums. Hope I have answered your query. Let me know if I can assist you further.
