This is just a very BAD dentist. He did an implant for me two years ago and I am still having problems. I went back to him at least six times and he adjust a little here and there and it never got better. He sent me to an Oral Surgeon and ENT and they said he needed to fix the implant crown which is scrapping against my tongue and causing it to be raw and sore. He gave me mouthwash which he says I did not get, not true! I have tried everything from medicine to herbal remedies to resolve this problem. I just went to a new dentist who told me Dr. Silman should have removed the crown on the implant and just made me a new one, because this one is crooked. News flash why didn’t Dr. Silman try that? I did not even know that was something that could be done. Yes he advertises cheap implants, but if you go to him for dental work you could end up in my situation and have a sore on your tongue for two years with no help from this dentist. He even told my Cigna insurance that he would not do anything to assist me and that I should just go ahead and file a complaint with them. Great customer services! He also has offices in Exeter, Blandon and Allentown, under Affordable Dental and Castle Dental, BEWARE!
