Definitely find another dentist. You should never feel forced into getting any particular treatment...they cannot just let you go with an ongoing infection and pain...that is ridiculous. I started with my current dentist a couple years ago and I made it very clear from day one that due to my RSD that root canals were off the table and they have never pressured me about it. They do sedation dentistry so when I needed 4 teeth pulled they just knocked me out and did it all at once...so much better for me and no stress. I have two bridges that cover a total of 7 teeth. It was expensive...but they did a payment plan for me with no interest and it was worth every penny.
