Now i got a ring in my tongue......hard to eat but w/e. Nobody thought i'd do it...hell i'm glad i did. its worth it to relearn how to eat and be careful, and its helping me to obtain better teeth...believe it or not...the constant gargling and the constant brushing and the cleaning right after eating is making my three times a day into six times a day....they have never been so damn pearly white!!...hehehe
