toothache

I need some advice please from all you fellow zappers. I have a terminator II and recently went to the dentist for a cavity/toothache on tooth #11. The dentist didn't give me any Antibiotics or painkillers. The dentist says the tooth needs either a root canal or extraction. I have been using the terminator II on the area but have been experiencing some burning around my upper lip and cheek area. My question is will the terminator II take care of this situation or is root canal or extraction in the very near future? Any advice would be greatly appreciated.
