I've been seeing this guy since I was in 4th grade, I am currently a SENIOR in college. I've had braces on and off about 3x with this guy. I followed all the rules with retainers, my parents are Asian and they make sure I do so or they get very angry.
They charged my parents an for 2 of the 3x that I got braces back on. They DO NOT seem to have any of the solid techniques, they use methods from the 1950s. Rather than just installing permanent retainers like my new orthodontist did (started seeing him my freshman year of college). He just kept putting braces back on and charging me. The braces DO NOT look good, they are the shiny metal that stands out; my self-esteem dropped significantly when I was in high school because of this. No one in high school even has braces anymore.
My new orthodontist was cheaper, and gave me the clear braces.
