question: I had a root canal 10 years ago, now the same tooth has become infected. My regular dentist send me to an endontist who said I should get the tooth pulled (don't have one above it anyway ) however, he would not pull it. So I called my regular dentis back..but I have to wait 20 days for the next available appt. Meanwhile I am in such sever pain that I am almost crippled every 3 hours no matter that I am taking Pen V K and Flagyl. I have been on both for 6 days, along with Motrin 800 every 4 hours and STILL its killing me. Should I seek another dentist, and will extraction help the pain go away? I am very worried about the infection going to my face, throat and neck not to mention my heart!!
