Hi,
I am 21 years old and wore braces for 3 years when I was about 13-16. I wore my retainer religiously and lost it at some point. But I quickly went back to the orthodontist the next week to have another one made. The second retainer never fit the same, and now my gap is reappearing. My dentist told me that the orthodontist screwed up and that now I am a perfect candidate for Invisalign. Too bad I cannot nearly afford it! My gap is very small and not very noticeable, though it is noticeable to me.
Are there any cheap alternatives to closing it? I've heard about Orthofill bands, but I'm scared that they will mess up my teeth. Any advice is much appreciated!
