PLEASE STAY AWAY. I had six old fillings replaced by Dr. Ma. Eight months later, I was having problems with my teeth again and went to see a new dentist under my new insurance. My new dentist was appalled at the shoddy work done by Dr. Ma. All six fillings have to be replaced, again. One fell out on its own. Bacteria built up under another and I am in danger of losing the tooth. Shame on me for not believing what my eyes were telling me: if a clinic looks sketchy and temporary, then the work you will get there will probably be the same.
