Reason for braces: no molar contact. On tray 11 of 24, front teeth are straighter, but still no molar contact yet. Is that OK? Top front teeth rotated over the years so the arch narrowed. Night clenching kept things pretty well in place, but eventually my lower jaw couldn't move back any further and I was losing the ability to chew on my molars much at all. Then I got Invisaligns so although my teeth are getting straighter, the uppers and lowers are completely independent and the gap between upper and lower molars is even wider. Is this wrong or normal?
