An orthodontist in East Flatbush landed a deal for her new toothbrush invention on ABC’s show "Shark Tank."

Dr. Bobbi Peterson, an orthodontist with over 20 years of experience, first made a name for herself in 2016 when she opened Aces Braces in Brooklyn.

She used her talents to develop the Big Mouth Toothbrush, an electric toothbrush with a head described as 1.5 times the size of the average toothbrush head.

The Big Mouth Toothbrush sold out in just 24 hours after airing on "Shark Tank."

Peterson says pitching the product on the show was a dream come true.
