I believe Dr. Kwon has been working at the Wellesley Dental Associates part time. That is where I was treated by her. I think she is a very good dentist, a very thorough dentist with a good chair-side manner. I am only a little wary when dentists urge treatment for things that don't appear to bother me. I have a lot of old amalgam fillings which work fine for the most part. And in doing some work on my teeth, some of my amalgam fillings had to come out, to be replaced by the white ceramic ones which are the only ones used at this practice. The amalgam fillings haven't bothered me for over 20 years but once the ceramic was put in, I experienced some discomfort when chewing certain foods. I went back and Dr. Kwon fixed the pain problem. But I decided to hold off treatment on my other teeth (because they aren't bothering me at the moment).
