Problem for me was that I had an existing infection that caused considerable extra pain. Additionally the local anesthetic had little effect on me (it has worked before so it was somewhat puzzling), and the surgeon had to inject me 8 times (2-3 being the typical dosage and 11 being the absolute safety limit). It still was extremely painful.
Were they injecting u with Lidocaine?
Do u mean that even after 8 injections u could still feel pain?
Did the tooth pain radiate out into your face, neck and/or ears?
