I had my braces removed about two and a half years ago, and i was pretty pleased with the results (except for the fact that one of my front teeth is switched with the one next to it, which will require cosmetic surgery). My top retainer still fits for the most part, but not the bottom one because I never wore it. Both my top teeth and bottom teeth protrude outward though, and I just discovered "tongue thrust" and realized that I probably have it. I think I need braces again, but will it be covered by dental, and do you have any advice? Also, since the dentist never diagnosed me with tongue thrust, isn't my teeth moving since braces kind of the orthodontists fault?
