Nerve Damage Pain Recurring

[INMH]

Hello. A couple of weeks ago I posted a question trying to figure out what the pain I was having following my cavity filling was, and the answer I proposed (that was reinforced by the answer I got here) was that my nerve had been damaged by the needle the dentist used for the anesthetic.

The pain is all but gone now, but I'm concerned again: Through... Perhaps August 9th thought the 19th, I didn't have any pain. None whatsoever. I thought it was gone. But around about the 19th, the pain started to recurr; it's kind of just popping up without my provoking it. It's not as bad as it was when I first got it, and it goes away pretty quickly, but again, I'm alarmed because when the pain happens I'm not actually DOING anything that should be causing pain, and because this came on after just over a week without any pain at all.

Question: Should I be concerned? Could the nerve be healing incorrectly? Or is it just, in fact, healing, and the pain I'm feeling as it does is normal?

Yes, yes it is. The receptionist who gave me the paper said orthodontics, but the paper I was given to give them at the place says 'Endodontics'. I certainly hope they'll figure it out; I'm getting a complex from this... Thank you again for all your help!

Do you mean an endodontist?  An orthodontist is a doctor who puts on braces to straighten teeth and are focused on the relationship of the jaw/bite.  

An endodontist is trained to manage the root canal and associated nerve inside the tooth.

Well, hopefully the specialist will be able to figure it out.

I don't know why either. It's just something I noticed, which is why I'm confused. Pressure and temperature have been very effective in alleviating the pain, though. My mom got me a slushie the other day, and my jaw happened to be aching at the time. When I drank it, it helped immensely and actually made the pain go away for a while.
My dentist recently recommended me to an orthodontist to check and see if I might have an abcess under the teeth I had filled; I didn't have a chance to run the nerve-damage theory by him, but I still stand by it because in all of the cases of abcesses I've heard of (And at this point I've read a LOT of different sources depicting the symptoms of a tooth abcess), I should, according to just about all of them, be getting sensitive to hot and cold, as well as the tooth in general being more sensitive, but I'm not.
Chewing doesn't hurt, hot and cold don't hurt, and the pain these articles describe don't quite seem to match the pain I experienced and continue to. I'm still convinced it's nerve damage, but the orthodontist will be able to find out for sure.

I'm not sure why posture is having an affect on the pain except that the firing of other nerves may help to compete with the sensation of pain, such as when something hurts and by putting pressure on it, it helps to lower the pain.

No, the tongue thing has actually gone away. I've made sure I've checked and double-checked, and I can definitely feel with it again. It's mainly just the pain flaring up again, and I recently discovered that altering my posture helps alleviate it a little. I have awful posture, and my head tends to droop when I'm relaxed, which might have had an affect on the nerves in my face; I wouldn't know, this is the first time I've ever actually taken an active notice of my nerves.
Thank you so much for answering my questions.

Is the sensation on the tongue or anything else altered again?  If not, I would keep an eye on it and monitor the situation.  It sounds like its healing and it doesn't sound like its a bite problem.
