Britney returned to the Century City Hospital yesterday to pay a visit to "dentist to the stars" Dr. Bill Dorfman (according to Access Hollywood), the same guy who fixes jacked-up grills on Extreme Makeover!

Britney's trip to the hospital yesterday was the first of many live broadcasts on X17online.com, but since some of you may have missed it, here it is!
