I had a root canal done that required two appointments. Her office called the next day after each visit to see how I was doing. One week after the procedure I received a thank you letter in the mail.
The one negative is that I wasn't told of the fees up front. I do have dental insurance but was not advised as to how much I would have to pony-up. Then as I was leaving the office I was told that they expected me to pay the estimated amount that the insurance wouldn't cover.
This is the only time I have been to an endodontist, so I really don't have anything to compare it to.
Overall, I was happy with the care I received.
