Dr Zervas is rude and abrupt and doesnt like to be questioned. All I wanted to know was what he was doing and why he needed to replace a filling that was NOT bothering me. Also did not use the topical anestethic, he put the needle right into my cheek which was very painful. Dont go here just in case he is having a bad day or doesnt like the fact that you dont want to pay $400 for a mouth guard.
