Thanks for that. I figured as much as what you've said, though it's always good to know for sure. I'll be seeing an orthodontist in a month's time so I'll be able to know for sure whether I need extractions or anything, although at this stage I sort of doubt it.
What do you mean by "lip support" too? I know about lip incompetence, so do you mean to say the upper lip could droop down more?
