In a new interview, the Teen Mom OG star, who faced criticism for giving Sophia such a large amount of cash, explained why she was such a generous tooth fairy.

“Loosing your teeth should be something special, I like to add passion and something special to everything including loosing teeth," Abraham explained to Rumorfix on Thursday. "These years are flying bye and soon $600 won’t be surprising to my daughter and the tooth fairy will just be imaginary and made up, so $600 for one tooth is a great addition to her college fund and let’s her have a big surprise when she woke up that morning.”
