I really, really have sympathy for you - beacuse ive experienced extremely bad tooth pain myself. I went to my dentist who orginally noticed nothing, then went to my doctors who told me i had gingavitus!!!!! (which is where ur teeth eventually fall out!!!!!) and he gave me medication, but i was in soo much pain i ended up waiting in A and E where i was told to go back to my DENTIST!! So i did.... she took an x ray of my front teeth (where i was experiencing extreme sensitivity and couldnt eat or walk down the street - because of the cold!) and found i had an infection in my gum - from when i fell over as an 8 year old! dont ask...
Anyway, my point is i totally understand the pain and frustration u must be going through! If i were u i'd insist that ur dentist did i x ray of ur wisdom teeth to see at which angle they were growing and also a genrally x ray of ur mouth to see where the problems coming from...
