Dr. Williams in Denise Alexander's office completed my root canal and filled several cavities to my satisfaction. I'm usually afraid of going to dentists but Dr. Williams put me at ease and always made sure I was not in any pain during procedures. She also did a good job in fillling a rather large cavity where a previous filling had fallen out; now it looks like nothing had ever affected that tooth. The crown she placed is also doing well, though I should say that she was very forceful when doing the root canal and crown placement; I felt like my tooth was going to come out. Otherwise, she is a pretty good dentist.
