Big Mouth Toothbrush is an innovative electric toothbrush brand designed specifically for people with larger mouths. The product was developed by Dr. Bobbi Peterson, a Brooklyn-based orthodontist, who launched the business in December 2022.
Driven by her passion for improving oral health accessibility and comfort, Dr. Bobbi created a toothbrush that addresses a unique market gap — providing a powerful, oversized electric toothbrush for people who struggle with standard-sized brushes.
Shark Tank Appearance
Big Mouth Toothbrush gained national attention after appearing on Season 14, Episode 15 of Shark Tank USA in March 2023.
During her pitch, Dr. Bobbi asked the Sharks for $150,000 in exchange for 10% equity, valuing her company at $1.5 million.
The pitch attracted the interest of Shark Barbara Corcoran, who ultimately offered $150,000 for 20% equity, which Dr. Bobbi accepted.
