This is for his practice: CHAMPION DENTAL in Scarsdale, NY . I went there in Nov 2016 for a routine checkup. My previous dentist retired and i needed to find a dentist close to where i live. Once there i was told that i needed to have a cavity filled by a Dr. Kohn (spl?) . I should have know by the name because it sounds like the word CON, as in i got CONNED. 3 months later the filling fell out and i went back to have them take a look but they are now CLOSED! No notice, nothing. The phone line is disconnected and they have just disappeared. Also, they charged me $350 for a cleaning that should have been covered by my insurance. Now, my current dentist said that i need to have a root canal because they botched it so bad by drilling down to the nerve. i didn't even need the filling in the first place! I guess at this point, it doesn't make sense to even write a review, but i'm hoping that someone out there may know what the hell happened to them and all of the patient records??
