I send my deepest appreciation for your time, kindness and careful explanation about treatment for my tooth.  My sister and I were so impressed with your skill and tenderness.  Thank you.

Yesterday you did a root canal on my tooth #12 and I'm very comfortable today.  I'm writing to thank you and your assistant Sue for making the procedure so easy and efficient and relaxed.  People who think of a root canal in a negative way have not had one done by you.
