I'm 35 years old and had traditional braces 15 years ago. Because I didn't wear my retainer, my lower set of teeth have shifted quite a bit. I've seen 2 Orthodontists to quote Invisalign vs. braces. After reading all the Invisalign reviews, I'm really having second thoughts. I really don't want to wear braces all over again (at my age!) But I don't want to fork out more money if Invisalign doesn't work for me. Any suggestions?
