I was concerned with all the amalgam I had in my mouth. Dr. Mason was able to remove all the mercury fillings I had and gave me very pretty teeth. My health continues to improve, one year since the procedures, and I attribute the improvement to removal of mercury fillings. They took all precautions for me and themselves when handling the mercury. They treat you like one of the family. I traveled four hours to them since I wasn't able to find a dentist in Oklahoma that was concerned with the level of mercury I had in my mouth. They shared my concern and gave me my health back. Can't say enough about them. This comes from a person who hated and was fearful of dentists because of past experiences. They got me through it all! 5 Stars all the way!
