Also, i went to an oral surgeon, not a dentist. Also look in google for "dry socket". I was scared of getting this, but thank God I didn't. Supposedly the pain is real bad, even worse than childbirth!
It could be an ater effect of the surgery.
Even with insurance my minor surgery cost over 1k, that's expensive I think, for it only took the surgeon 10 min to do my operation. But I also developed a "bone cyst" from leaving one impacted tooth in there too long, so they charged extra to have that taken out and have it sent to a lab to be checked for cancer (standard procedure).
