Q. My daughter in law went for a scale and polish at a private dentist and the dentist hit a nerve. The dentist said he has to do a root canal to fix it. My daughter-in-law was in terrible pain. The root canal was done and they sent her home with no medication. Since then she has been in horrible pain. A tingling, sharp pain that is non stop.The dentist says he cant see her for 4 more days. There is no swelling, no fever but no relief even with regular painkillers. Any advice?
