Hi, I was wondering if it's possible to widen the dental arches with invisaling? first time got 4 teeth extracted. ended up with no lip support flat cheeks, and narrow arches. Now trying to open up extraction sites to place implants in. ortho wants to open up spaces more pushing my teeth back using TADs, and sure smile braces, after open up spaces he wants to change to invisaling to widen my arches. Will invisaling works in adults? Will this be worth it?
