Howdy.
I had an experience very similar to the ones above. Braces not on for long enough, and retainer not worn.

But on my bottom teeth my dentist has put on a permanent retainer. Kind of looks like braces on the inside I suppose, but just on the 6 front teeth. This has kept my bottom teeth nice and straight. At the time I asked for one on my top teeth, which he said I didn't need. In hind sight I shouldv'e made him do it because it didn't take long for my teeth to go back to the way they were.

I would love to have my teeth restraightened, but havn't looked into it much yet, as we have had other priorities. Iam interested in finding out about the braces on the inside of your teeth: are they any more expensive?
