Tell us about yourself!
Thank god for your brilliant idea. I lost my retainer and my parents were going to make me pay for it ($300). This is basically my only (much, much, much cheaper!) alternative. Unfortunately, my mom insists I talk this out with my orthodontist, to see if it's "acceptable" and all. It's probably not - for one thing, it's uncommon; and secondly, the orthodontist will obviously want to make some money off of my mistake. They're not going to approve of a version that's up to 60 times cheaper than theirs.
