I paid £3500 for Damon braces, my teeth weren't great but not absolutely terrible either. I look back at photos and think they seem a lot worse now than they did at the time because they are so straight now. I think I wore mine around 18 months or so. Price also included fixed retainers, so although I have a removable retainer to wear at night I also have fixed wires top and bottom now, which has meant they've not moved back so easily.
