Dr. Moon is the worst orthodontist. I got four teeth extracted for orthodontic treatment. I’ve been going there for 10 years and he couldn’t close the gap between those teeth that he asked to be extracted. My general dentist asked me to seek the second opinion. Finally I found excellent orthodontist who finished my treatment. But I got two implants on lower jaw. Dr. Moon is the worst. Always seek second opinion! If possible, don’t extract teeth that he asks!
