The Visionary Orthodontist: Dr. Bobbi Peterson Biography and Pitch

Dr. Peterson’s pitch was compelling because it addressed a clear, painful problem: the difficulty of maintaining meticulous oral hygiene with orthodontic appliances like braces. Her passion and expertise as a practicing orthodontist immediately established her as a credible authority on the subject, which is often a key factor in securing a deal on Shark Tank.

The Deal That Shook the Tank: Barbara Corcoran’s Investment

The negotiation for the Big Mouth Toothbrush was intense, a true battleground of valuations and terms. While Dr. Peterson entered the Tank seeking $150,000 for a 10% stake, the Sharks, including Mark Cuban, Kevin O’Leary, and Lori Greiner, expressed concerns over the high price point of the electric toothbrush, which retails at $99.99, and the company's relatively low pre-show sales.

Ultimately, it was the real estate mogul and seasoned investor, Barbara Corcoran, who saw the immense potential in the product and the founder. Corcoran recognized that Dr. Peterson’s expertise and charisma could successfully market this specialized dental tool.

This deal represented a significant increase in equity from Dr. Peterson’s initial offer, doubling her stake.

The royalty clause provides a steady, long-term return for the investor, while the 20% equity ensures Corcoran is deeply incentivized to grow the company’s overall valuation.

The company quickly moved into pre-order mode to manage the sustained interest.

Current Status and Valuation (2025)

As of the 2025 update, the Big Mouth Toothbrush is not only operational but is reported to be thriving. The company's unique selling proposition (USP)—a revolutionary design for improved oral care—continues to resonate with consumers, particularly those with specific dental needs.

The company also maintains a philanthropic element: 40% of the proceeds from the sales of the pink-colored toothbrush are donated to charity, adding a layer of social responsibility to the brand.

The product is a clear winner in the specialized electric toothbrush market, appealing to a broad range of users, including children, adults with limited dexterity, and, most importantly, orthodontic patients who require a more effective cleaning tool to navigate the complexities of braces and other dental appliances.

The Impact of the Oversized Brush Head on Oral Hygiene

The core innovation of the Big Mouth Toothbrush is its oversized design, a feature that addresses a significant gap in the traditional toothbrush market. This design is more than a gimmick; it is a functional advancement in the pursuit of superior dental health.

Key Benefits of the Big Mouth Design:

The larger surface area of the brush head allows it to cover more ground simultaneously, making the brushing process more efficient and effective. This is particularly beneficial for:

• Braces Patients: The brush can more easily clean around the brackets and wires of orthodontic appliances, reducing the risk of plaque buildup and gingivitis—a common issue for those with braces.
• Periodontal Health: By reaching more surface area, the brush encourages better gumline cleaning and overall periodontal health, which is crucial for preventing gum disease.
• Time Efficiency: For busy individuals, the ability to clean a larger area of the mouth in the same amount of time means a more thorough clean with less effort.
• Accessibility: The design can be a significant aid for users with limited mobility or dexterity, such as the elderly or those with certain physical conditions, making the daily chore of brushing simpler and more effective.

This focus on solving a high-friction problem for a dedicated customer base—the orthodontic market—is what elevated the Big Mouth Toothbrush from a simple product to a successful, high-value entity. The initial valuation sought by Dr. Peterson, which was questioned by the Sharks, has been largely justified by the product's explosive post-show performance and sustained market interest in this dental innovation.

Future Outlook: What’s Next for Big Mouth Toothbrush?

With the backing of Barbara Corcoran and a proven product-market fit, the future for Big Mouth Toothbrush looks exceptionally bright. The company is well-positioned to expand its product line beyond the initial electric toothbrush, potentially introducing specialized flossers, water flossers, or other accessories tailored to the needs of orthodontic patients and those seeking advanced oral care solutions.

The partnership with Corcoran will likely focus on scaling production, optimizing the supply chain, and expanding distribution channels, possibly into retail giants like Target or Walmart, or through dental professional networks. Dr. Peterson’s journey—from a practicing orthodontist in Brooklyn to a successful inventor landing a major Shark Tank deal—serves as an inspiration for entrepreneurs in the health and wellness space, proving that a unique solution to an everyday problem can lead to extraordinary success and a significant impact on public health.
