<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a toothache and gum cheek soreness . Went to dentist 2 weeks ago and he said I need root canal. But I have been so sick with flu virus as well, I havent been up to the procedure and keep putting it off. I have been on antibiotics the whole time but just not getting better. Feel miserable. Should I have the root canal while I feel so sick, or keep waiting till I feel better?  <response>: Hello:Thank you for trusting Chat Doctor. I suggest you to explain this to your dentist as well. Root canal treatment can be done in multiple sittingstwo or three depending on infection, pus etc. I suggest you to take the first sitting done. This will eliminate pain, so you can feel better. This first sitting will take as long as 20-30 minutes. You can take the second sitting after a week or 10 days,meanwhile you can get well from flu as well. Too much of antibiotics is not recommended. Regards.
