I have large buccal corridors from extracting four teeth on top, and none at the bottom. I have large buccal corridors after extracting two wisdom teeth on top and two bicuspids on top (the bicuspids were crowded, not aligned with the rest of the teeth, and more inward toward the roof but still in contact with other teeth) as well. I had no teeth removed from the bottom, not even the wisdoms below due to expenses. Help would greatly be appreciated. Thanks! Extra: Can veneers help? Or any commonly used upper palate development appliances on adults? Type of braces that widen smile?
