2 Chainz Tries Out The World's Most Expensive Toothbrush

Smile.

Is a smile worth $5000? 2 Chainz is here to help you find out.

On his latest adventure with GQ where he tries out "Most Expensivest Sh--," Tit checks out the Reinast luxury toothbrush.

"Five thousand motherf--kin' dollars for a toothbrush," he says in awe.

He meets with a dentist, who tells him some info about the toothbrush -- it has a titanium design and patented antibacterial coating, and they send you new bristles every month -- and later she shows him the right way to floss (in case you were wondering, you're supposed to do it before you brush, and wrap the floss around your middle fingers).

Chainz has been getting used to expensive stuff of late, but it wasn't always that way. He was recently with some friends, who reminded him of his humble beginnings.

“They said, ‘Yo, Tit, do you remember when you used to eat bread and Kool-Aid all the time?’” he told MTV News last week, when we asked about the "Most Brokest Sh--" he's ever done. “It was one of them moments where I had to reflect on how I had the big glass of the sugar Kool-Aid, and I had the bread on top, and that would be my holder. And I’d take the bread off, dip it in the Kool-Aid, eat it. But it was almost because we wasn’t eating like that.

“That made me remember really where I came from."
