Sorry for your tooth pain.
I am not a doctor, but having suffered through trigeminal neuralgia and subsequent decompression surgery, I have learned a great deal. It would be unusual to have trigeminal nerve pain across your upper front 2-4 teeth unless you really mean it is all on the same side of the mid-point. There are two trigeminal cranial nerves ..... one originating on each side of the brain stem and coming each from the back of the head around to the face from both sides. Each nerve splits into three branches as it comes to the face. It is not unusual to have pain in just one or two branches (depending upon where the compression on the nerve is occurring), but it normally ends at the mid-point of that side.
My trigeminal pain was only in the middle and upper branches so my pain was across my forehead and across my cheek, but not along my jaw ..... but both ending at the mid-point. My trigeminal neuralgia was unrelated to my acoustic neuroma and in fact, was on the opposite side.
If an AN is pressing on the trigeminal nerve, it can cause trigeminal pain. In most cases, it is relieved when the AN is removed and/or decompression surgery is performed.
If this is a sudden new symptom and it does not stop on its own soon, I would certainly contact my doctor and tell him/her of this new symptom.
Hopes and prayers that it is not trigeminal pain, but a sinus infection. Let us know how you are doing.
