Paul McDonald has made a name for himself on American Idol not only for his musical talent, but also for his pearly whites! So what's his secret?
"I brush 'em once or twice a day, I try to keep them decent," Paul explained to MTV News Thursday night.
And Paul even decided to promote the toothpaste he uses (since high school) in hopes he'll get a deal out of the company — Crest Advanced Vivid White.
Hey, if he doesn't get named America's idol maybe he can do commercials!
"For some reason it keeps them lookin' all right, you know?" Paul added. "And I was going to be a dentist beforehand, before all this rock 'n' roll stuff started, so I figured I need to keep my teeth decent."
"I'm being dead serious," he continued. "I went to school for biomedical sciences and I was going to be a pediatric dentist before the rock 'n' roll singer/songwriter path took off."
Okay, if not commercials then maybe dentistry?
