Can braces help clear sinus issues?

[allysonholley]

I have always had sinus issues and recently the farmer we buy goat milk from told me that her orthodontist (who is retired now) said braces can correct behavioral issues (including ADHD) and sinus issues along with a lot of other things. Said it was due all the nerves that could be out of whack with an improper bite. Ever heard anything like that? The orthodontist I talked to in OKC disagreed.
