I went to the dentist to get a root canal done on the tooth way in the back (not the molar) on the right side. Unfortunately, since it was too far back, my dentist stopped my root canal and plugged it with filling (called something with a 9 in it). He told me that he wants to see me in 2 weeks bc we have to let it heal. If they can’t get it the second time, they’ll have to refer me. Basically I have an unfinished root canal. It’s been throbbing and aching for the past four days.
