Terrible, awkward, terrible dentist. The hygienists and staff are very nice, but I recommend not letting Dr. Ehrlich near your mouth with a drill. I should have stopped going after the first time I visited, when he awkwardly lectured me for being a few minutes late (because there had been a train problem on the CTA) and made strange "uh-huh" noises while he looked at my teeth. I went back because I liked the hygienist, even though I felt uncomfortable with the awkwardness of the dentist. The last time I went back for a cleaning, he said I needed 3 fillings even though I didn't have any pain in those teeth. I should have listened to my instincts and not had them done there, but I convinced myself it would be OK because it was just filling some small cavities. He kept my mouth open for so long and the entire 2 hour process was more painful than getting fillings should be. It hurt immediately and I couldn't chew on that side of my mouth, but I gave it a week to see if it got better. When it didn't, I went back in to him to have the fillings adjusted. It still hurt just as bad afterwards, and I felt very uncomfortable in his office because he seemed frustrated with me for saying that it didn't feel right. But it kept hurting, and I didn't feel like he knew how to fix it or like I could trust letting him near my mouth again. My jaw was out of place and it started causing problems all through my back and neck. I finally had to go to another dentist to fix what Ehrlich had done, and it took me an entire month and a half to stop feeling pain in my teeth every time I chewed. My jaw, neck and back are still recovering. When I called to explain the pain he had caused, he said nothing but "OK" and expressed absolutely no empathy until I told him that most people would at least say they were sorry. I have talked to other people who have had similar experiences there, but Ehrlich doesn't seem to care at all if any of his patients are upset with his services. Even with the painful fillings, if he would have been more caring in dealing with me, expressed any level of concern for the painful impact that this had, or been more active in trying to fix the problem he created in my mouth, I would not have written this review. I will never go there again, and I wish I had never gone there in the first place. read more
