tooth abscess (i think) and oil pulling, healing process hurts, doubled in size, help???

Hi! I dont have reports for a cure or anything, but I need your help, I really dont know what to do. My dentist has said before that I have a dying tooth and one day I would need a root canal, I was and still am against it and within last week i noticed an area above the dying tooth starting to ache and swell a bit, especially when i touched it. After 5-6 days I decided I needed to do something as I suspected it was either a tooth abscess or an infection. To try and combat this, I oil pulled with coconut oil. The first day it didnt swell as much and there were not much changes, however, the next day (which is today) when i OP and rinsed with salt water, i think i saw a small little hole thing draining out the pus, a fistula was it called? That didnt feel too bad, but then throughout the day it started getting worse, especially after I ate some durian (im thinking as the durian is pretty heaty, it might have triggered something?) so as soon as I got home, I OP again and rinsed with salt water after. I took a nap and woke up 2 hours later to find the swelling has seemingly doubled in size. Is this normal? I know some people have bad healing reactions and I was wondering whether this was one of them. Please help, I really dont know what to do. Tweet
