Shark Tank Big Mouth Toothbrush Update 2025 | Season 14 (2025)

While working as an orthodontist, Dr. Bobbi Peterson noticed that many of her adult patients with braces were dealing with gum disease because their toothbrushes weren’t cleaning well enough. To fix this, she created the Big Mouth Toothbrush, an oversized electric toothbrush that makes it easier to clean every part of the teeth and gums. It also helps support breast cancer awareness, with 40% of proceeds from the pink version going to the cause. Will the sharks get behind this idea? Let’s find out in our Big Mouth Toothbrush update and pitch recap.

Shark Tank Big Mouth Toothbrush Pitch

• Entrepreneur: Bobbi Peterson
• Business: Big Bristle Toothbrush
• Ask: $150,000 for 10% equity
• Result: $150,000 for 20% equity plus $2 royalty in perpetuity
• Shark: Barbara Corcoran

Bobbi started her pitch by explaining how her product can help customers avoid periodontal disease, which affects over 50% of the world’s population.

Her oversized Big Mouth Toothbrush promises a spa-like experience while tackling gum disease, a problem affecting millions.

She needs an investment to hire staff, secure packaging space, and launch her product into retail stores.

The Big Mouth Toothbrush is a large electric toothbrush designed to clean teeth and gums better. Its big brush head covers a larger area, so you get a deeper clean with less effort.

Bobbi designed it to help people avoid gum problems. She is the first Black person to make an electric toothbrush.

This toothbrush is great for people who wear braces or worry about gum health. It makes brushing easier and faster.

It has five options to suit different needs. The wide brush head ensures it cleans every part of your teeth and gums.

Customers can order the toothbrush online. It is packed and delivered straight to their door. It’s easy to use and works better than regular electric toothbrushes.

The sharks examine their samples and test the toothbrush. Lori Greiner finds it cool that an electric toothbrush has five settings, saying she’s never seen one like it.

Furthermore, the larger brush head reduces brushing time by half, adding convenience for users.

Kevin O’Leary questions why major toothbrush companies wouldn’t simply create a larger brush head themselves. However, Bobbi clarifies that a patent protects her design.

As the conversation shifts, Bobbi shares more about her journey. She explains that she built the business despite significant challenges.

After having her daughter as a teenager, she worked hard to finish high school, college, dental school, and an orthodontic residency.

Remarkably, she opened her own practice just one week after completing her residency.

When the Sharks discuss the business potential, their responses vary. Lori appreciates the product but feels the oral care market is too crowded and opts out.

Robert Herjavec acknowledges Bobbi’s impressive accomplishments but believes the competition will be tough, so he declines.

Mark Cuban praises her for managing two ventures—her dental practice and the Big Mouth business—but feels she is spreading herself too thin and steps away as well.

Barbara Corcoran asked how they planned to use the funding, and Bobbi explained they would hire staff, secure packaging space, and enter retail.

Although Barbara admires her determination, she decides the business isn’t the right fit for her and also declines.

Finally, Kevin considers the potential but describes the market as tough. He proposes $150,000 for 25% equity and a $5 per unit royalty.

Bobbi finds the terms unfavorable and counters with $150,000 for 20% equity and a $2 royalty.

Barbara re-enters and offers $150,000 for 20% equity plus $2 royalty in perpetuity, which Bobbi accepts.
