Dr. Siegel used to be my dentist. I made the mistake of leading my good dentist for this many since Siegel was on the health plan. He immediately started filling cavities that really weren't decayed, put on badly seated crowns, caused me to have multiple root canals that I then had to have redone, and I even needed an implant because of his shoddy work. After the fact I noticed that he has had multiple malpractice suits filed against him. Do not let the nice office and his pleasant manner fool you. I have spent at least $20,000 dollars trying to repair what this man did to my teeth! Please, avoid him at all costs. He has been reprimanded several times, I cannot believe he still has a license!
