Why Does My Teeth Become Sore After Root Canal?

I am in the midst of a very long root canal procedure in South Korea. A tooth which had been filled twice became very sore and sensitive, so I saw a dentist and he said I would need a root canal. I have gone to him 2 times a week for two months now. Because I still feel pain at the apex of the tooth, he keeps filing a little at a time. I currently have some temporary filling in to see if I'm ready for the next step, but this is causing swelling and pressure/pain in the gums above and what seems like my sinuses on the left side of my face. I am not sick with a cold or anything like that, but my cheek seems swollen and hurts.

Hello,
There may be additional complications concerning this tooth such as a fracture or hidden canal. There could be a fistula with communication into the sinus. There is a surgical procedure known as a apicoectomy that can be considered if the non-surgical method cannot resolve the apical area. Visiting an endodontist that specializes in difficult root canal therapy should be considered due to the difficulties that you are experiencing.
You often need an antibiotic to control the spread of infection while treating the source with root canal therapy. I commonly prescribe amoxicillin. Some resistant infections can require a different antibiotic prescription. Anti-inflammatory medications offer relief during treatment as well. I suggest ibuprofen or acetaminophen.
Thank you for your inquiry.
