My dentist referred me to Chrysalis when the screw in one of my implants was loose and he was not able to fix it. I saw Dr. Gersana Segal and she determined that the screw was broken. She was able to extract the screw and while it was a different one than the ones they use, fortunately they had one the same in stock and she was able to replace. As this was an initial consultation, there was no charge - including the 3 x-rays taken. I liked Dr. Segal very much, as well as her assistant and Michelle, the Treatment Coordinator. All very lovely to deal with and a very professional organization.
