Severe Pain in mouth for years cant figure it out

[Tweety]

Hi.

I had no pain until I had a cavity filled twice. I think the dentist drilled too far in my front tooth and hit a nerve. I then went and got a route canal which did not help. The pain is severe and consist for the last 4 years. I pain goes all over my mouth and in my sinuses too. I've been to 5 different dentist afterwords and an ent specialist. They say all nothing is wrong but the pain won't go way. I've been taking motrin and allergy medicine and it does not help both it pain.

Any thoughts or suggesting would.be greatly appreciated.

Thanks in Advance.

Do you have x-rays that you could share? Need more information to give an opinion in this case.
