I had braces when I was young, but of course didn't wear my retainer. However, I still have it and it still fits, so my teeth haven't moved that much. The problem (for me) is that my top from teeth are overlapping and I hate it. I have gotten some quotes, which average about $4400. All have said my case would be very easy, with about 16 trays and 6-7 months of treatment. This seems high to me because my stepmom, who had very crooked teeth, paid $4800 for 32 trays and 2 years of treatment. Why is my quote so high then? Is it reasonable?
