2nd appointment with an orthodontist who said that at least one extraction would be necessary, and she would recommend fixed braces on the bottom teeth. She was happy to provide Invisalign on my top set, but has only done 4 cases and feels the bottom is too complex for invisalign unless the person has a lot of experience with it.
To be honest, I'm not keen on the idea of a) extraction and b) fixed braces.
Orthodontist was keen on lingual (which solves the visibility problem) but I really don't think I can go through the lisping and irritation!

Totally confused about what I should do.
Have any of you gone with invisalign knowing that it would be a difficult case?

p.s. There are no higher level invisalign providers where I live...
