Just a few more thoughts on the matter!
If crowding is mild, a palette expander should work. I think all those facial sinking in problems happen when the teeth probably weren't so bad in the first place. So now many are completely discouraged from extractions because of a few bad cases. I think the telling signs are with the twins studies, yes there's a difference, but it doesn't 'ruin' their faces. Yes by all means explore your other options if long term they are much better, but for a lot of us adults extractions are the only way for straight teeth.


^ Sure the one on the left is slightly set back and looks less 'pouty' than his brother, but they had thin lips anyway. So I believe it's mainly a genetic predisposition to developing the facial side effects after.

Tell me how you can fix these teeth without extractions? The palette doesn't appear that narrow, and even if one was used, I doubt enough space can be made in order to straighten them?? The patient probably has an over-jet as a result too, which can't be fixed by a palette expander alone.
It just looks like the person has too many teeth for their mouths!
