“Dr. Henley performed my root canal this past week and it was as fabulous as a root canal can be. I was very nervous about the procedure but I was in and out with zero pain and I felt just fine the day after (and still do today). I’ve had my teeth cleaned at other practices and been in more discomfort. I am so grateful that I have found this amazing practice and thank you for the magic that you did on what I thought was a destroyed tooth, Dr. Henley! Thank you!”
