The Middle is a new sitcom about a family in Indiana, and the daughter Sue (played by Eden Sher) has braces. It airs at 8:30pm Eastern on ABC. It looks like full episodes can be watched on ABC's site (I don't know if it works for those outside of the US, though).

You can always try a proxy. I noticed that the episodes are also up on Hulu (which works better for me than ABC's video player), but again, I'm gonna bet that viewing is restricted by country, unless you use a proxy or something.
