The secret to Brooke Burke's smile

With 21 million people tuning in to watch the Dancing With the Stars season 11 premiere on Monday night, co-host Brooke Burke tells In Touch that it?s crucial she looks and feels her best. So she teamed up with Oral-B and Operation Smile to spread the word on how to keep teeth pearly white. ?A healthy, bright smile is one of the first things I notice about someone,? she told In Touch at the Townhouse Spa in New York. ?And with four kids, brushing our teeth is a big part of our whole routine at home.? From now until November 30, Oral-B is offering a 50 percent rebate on select rechargeable toothbrushes (visit oralb.com for details).
