I had braces 18 years ago, and about four to five teeth have moved very slightly. Orthodontist said only 10 sets of trays would be needed to fix the problem. I feel like $3,800 is alot of money. And the attachments frighten me a bit, lol, and they seem very noticeable. just looking for advice or opinions of others.. And costs you have paid for a 5-6 month treatment
