Does Suzhou tooth do root canal treatment want how much money? I consulted Mayo Hospital and said that it would cost 880. Is it expensive?

I have been to Mayo twice for root canal therapy. Two molars are the innermost teeth, 680 each. The first two times were anti-inflammatory and dredging, and I forgot the name. I'll fill it out next time, first one, then the second one. After that, the doctor might as well make a crown. But I didn't ask the price ... but mine is Mayo in Changsha. Let me give you a reference.
