When I was younger I had an underbite. I was told I needed jaw surgery by an orthodontist but my parents did not want me to receive that so young. I saw a different orthodontist and I was given a device for my jaw which attached to my expander at night time. It helped bring my bite to a more normal stage where I then received braces. Til this day, I know it was not completely fixed with how my teeth are aligned and the jaw discomfort I experience. I find myself my whole life clenching my teeth and Jaw, feeling like my throat is blocked, and always saying “my tongue is too big for my mouth!”
