hello,

six dental injections is a goodly amount in one sitting. the dentist may have hit your nerve with the needle; unfortunately, after the first injection, you would not feel this because you would be numbed by the excessive anesthetic used.

trigeminal neuropathic pain is best managed with medications. a thin slice MRI could be useful to rule out a vascular compression on the trigeminal nerve, however, your symptoms sound consistent with a traumatic nerve injury. i would suggest making an appointment with an oral surgeon who does microsurgery on the trigeminal nerves to see if there is a possibility of surgical repair. these injuries are best treated sooner rather than later.

best of luck,

the researcher
