question: I get this random feeling in my tooth every few months which is hard to explain. It almost feels like my tooth is going to fall out of my head, but yet it is completely stable, kind of like a tingling feeling. It only ever happens in my first molers and I ve had the teeth checked to see if the nerve had died but nope still alive with no cavities. My dentist mentioned something about it could have something to do with a nerve desorder like MS but he couldn t put his finger on it and I m now living overseas - have you heard of anything like this before?
