I went to see this dentist about getting some very old amalgams replaced with newer materials. I was told that a 'complete occlusal adjustment' was required to keep from destroying any future restorative work. At my first appointment, he decided without my permission or consent to completely change my bite by sanding down all the cusps on all my molars. He said afterward that he believes every patient should have the same bite he has (canine rise or CO=CR) and any other bite will cause systemic illness, even if the patient is completely asymptomatic calling this 'biological dentistry'. After the procedure was done, my molars no longer touched causing numerous problems including pain and difficulty eating, talking or smiling. I called their office, but was told to come back in so he could sand all the front teeth down too. I have had numerous procedures by other top dentists to fix this but with only marginal success as he made no record of my bite prior to the OCA. I won't be back.
