Wonderful people and my experience was great! I was terrified and they couldn’t have been nicer. It really is no worse than getting a filling. Thank you so much!!!! I would highly recommend!

They were great! I was leaving on vacation in a couple of days, and they got me in for a root canal the same day I was told by my dentist that I needed one. So awesome!
