What can be done to help with small lower jaw? I’ve been through two rounds of orthodontic treatment and several extractions. I think I should’ve had palate expanders but it wasn’t suggested at the time. I know my palate is unusually small, it’s difficult to keep my tongue on the palate because there’s not enough room. I hate my receding chin and having to always obsess about keeping my mouth closed. It does not come naturally, it’s always an effort to keep the lips together. What type of treatment could help? I’m trying to figure out how to add photos.
