The root canal itself was quick, relatively painless, and not super expensive after insurance. But he couldn't do a crown, apparently that's only a dentist thing. Since my previous dentist closed his office, I asked for a recommendation and he gave me a referral.
The referred dentist did the crown just fine but the price gave me sticker shock: about 4x as much as the root canal itself, after insurance! It basically wiped out my HSA account for the year. When I went back for a general checkup and cleaning, the same dentist said they found SEVEN cavities. Which was a little mind-blowing since in the decade previous, my old dentist only filled ONE cavity and always complimented me on the state of my teeth.
I asked how much it would cost out-of-pocket to address the cavities and they gave a number somewhat north of $200. Oh, that's not so bad to have a bunch of cavities filled. Oh sorry, nope, that's the price PER CAVITY. I asked what I was doing wrong because I _had_ been flossing and brushing every day and got a very hand-wavy answer. I was in a literal state of shock so made an excuse about my schedule being full for the next couple weeks and beat a hasty retreat. After the root canal and crown, I literally couldn't afford to have seven cavities filled.
Fast forward a year and I finally find another dentist for a cleaning and evaluation and to tackle at least the worst of those seven cavities. You want to know how many cavities he found? None. None at all.
