39 yrs old, F. lower left wisdom tooth, mesial impacted, lower right wisdom tooth, horizontal impacted. Upper left wisdom tooth-missing. Presented to my dentist on in Dec 2008 for filling on upper #15 and #12. No pain symptoms, just getting filling due to my dental exam/xray showing the need. At time of fillings, tooth #14 had old deep filling. After filling 15 and 12, extreme pain, heat/cold sensitivity for week. Advil (1000mg) would relieve pain for a couple of hours. The next week, dentist adjusted filling. tooth & mouth pain did not go away. Next week, dentist, more adjustments, performed hot/cold tests. Dentist suggested tooth 14 had sensitivity, may need re do of old deep filling. This did not stop the pain. Next week, readjust all three, suggested root canal on tooth # 14. Also noted, lower left wisdom tooth bleeding excessive. Dentist showed me in mirror. Looked like the wisdom tooth had protruded more through my gum. Still having severe mouth and teeth pain on left side. It was hard for me to pinpoint the source. Dentist sent me to Endodontist for # 14 root canal. (jan 23, 2009) Back to dentist Jan 29, 2009, still pain. Dentist wanted to start over, back to before fillings. Drilled out all three # 15, # 14, #12. (upper left), cleaned, rinsed, put temporary fillings. Still have pain, swelling on left side. Have been weary of hot/cold. Last night, tried hot. Extreme pain in upper, then lower, and whole left side. It hurt to talk or move, had sensitivity to sound and light with extreme head ache. I will be calling the dentist today. Please help. could the lower impacted wisdom tooth be the issue? How can I help the dentist pinpoint the source of problem?
