This Dentist is a butcher. He performed an extraction, left a piece of tooth in and even after repeated visits and phone calls never bothered to take an x ray to see what the issue was. He prescribed medication that the pharmacist said wasn't on the market for years!
I had to go to an oral surgeon to complete the extraction that he messed up.
If you are a periodontist and decide to do extractions, you need to be competent to do this work.
I sent 2 certified letters to him and he did not even have the courtesy to respond, refund my payment or offer to pay for the oral surgeon who completed what he started.
Other friends have used Dr Fishbein and have had similar experiences.
