In a world increasingly driven by sustainability, health awareness, and cultural rediscovery, few innovations manage to intersect all three as seamlessly as RemoBrush. At the center of this movement is Omer Elrayah, a 28-year-old dentist, educator, and entrepreneur whose journey from Khartoum, Sudan, to the United States has shaped a powerful mission: to make oral care not a luxury, but a universal necessity.
RemoBrush is more than a product—it represents a shift in how we think about oral hygiene, sustainability, and accessibility. Built on centuries-old traditions and modern scientific understanding, the company is carving out a new category in lifestyle-driven health innovation.

The Man Behind the Mission
Omer Elrayah, from Sudan, before immigrating to the United States with his family after his mother won the green card lottery. He grew up in Manchester, New Hampshire, alongside his twin brother and two younger brothers, raised by a mother whose resilience would become the cornerstone of his identity.
After the passing of his father in 2010 due to lung cancer, Omer’s family faced a defining moment. Despite encouragement from others to return to Sudan, his mother honored his father’s final wish: to remain in the United States and pursue meaningful, impactful careers. Her perseverance through financial hardship and language barriers left an indelible mark on Omer, shaping his worldview and work ethic.
From an early age, Omer was drawn to dentistry—but not without resistance. He was often told that dental care was not essential, but rather a luxury. What struck him most was the source of that belief: individuals who themselves lacked access to proper oral care. That contradiction ignited a lifelong mission—to challenge the perception of dentistry and make it accessible to all.

Academic Excellence and Professional Growth
Omer’s academic journey reflects both determination and excellence. He earned a Bachelor’s degree in Biochemistry, followed by a Master’s degree in Oral Health Science in 2018. In 2022, he graduated from the prestigious Tufts University School of Dental Medicine, overcoming financial hardship and systemic barriers along the way. His academic achievements were recognized through full tuition coverage by the National Health Service Corps (NHSC).
Continuing his commitment to growth, Omer became certified in Oral Implantology from the New York Implant Institute in Bogotá, Colombia in 2024. Within just a few years in the oral care field, he achieved a remarkable milestone—serving as a Clinical Instructor at Harvard University School of Dental Medicine, where he teaches third- and fourth-year dental students.

The Birth of RemoBrush
RemoBrush was born from a simple yet profound idea: combine ancient wisdom with modern innovation to create a better, more sustainable oral care solution.
At its core is the miswak—a natural teeth-cleaning twig that has been used for centuries across Africa, the Middle East, and parts of Asia. Known for its antibacterial properties and oral health benefits, miswak has long been a trusted tool in traditional hygiene practices.
RemoBrush takes this heritage a step further by infusing miswak directly into toothbrush bristles. The result is a product that merges cultural tradition with contemporary design and functionality. The toothbrush features bristles that are 76% more environmentally friendly than traditional petroleum-based nylon, paired with a biodegradable bamboo handle.
This innovation positions RemoBrush not just as a product, but as a movement—one that challenges the dominance of plastic toothbrushes while offering a more holistic, culturally rooted approach to oral care.

Building a Startup Against the Odds
Like many early-stage entrepreneurs, Omer has had to navigate the complexities of building a company from the ground up. Without a formal business background or a network of entrepreneurial contacts, he faced a steep learning curve. From product development to branding, logistics to marketing, he has worn multiple hats—learning, adapting, and evolving at every stage.
These challenges, however, became a catalyst for growth. His passion for collaboration and learning has led him to connect with a wide network of founders, creators, and innovators. This community has played a crucial role in shaping RemoBrush’s trajectory.

Cultural Impact and Viral Momentum
RemoBrush’s rise has been amplified by a growing cultural presence and viral moments. One standout instance involved an encounter with UFC legend Khabib Nurmagomedov. In a spontaneous and chaotic moment, Omer successfully introduced him to the product—an interaction that was captured on video and resonated widely online.
Beyond viral content, Omer has cultivated relationships with influential figures across industries. Notably, he has collaborated with global icon Rihanna in raising awareness about the humanitarian crisis in Sudan. Public figures such as Jacob Berger, Guy Christensen, Adil C, and Shaykh Rasoul have also shown support for RemoBrush, helping to expand its reach and credibility.

A Lifestyle Brand with Purpose
RemoBrush is not positioned solely as a dental product—it is a lifestyle brand rooted in intention, sustainability, and global impact. It speaks to a generation that values authenticity, environmental responsibility, and cultural connection.
Omer’s broader mission extends beyond oral care. Through his apparel brand, Elrayah Apparel, he has donated over $100,000 to support refugees in regions such as Sudan, Palestine, Syria, and Lebanon. These contributions have provided emergency relief, food, water, and shelter to communities in need.
This philanthropic commitment reflects a deeper philosophy: success is not measured solely by personal achievement, but by the ability to uplift others.

Looking Ahead: The Future of Oral Care
As RemoBrush continues to grow, its vision remains clear—to become a global leader in sustainable oral care and to redefine how people approach dental hygiene. The company aims to replace traditional plastic toothbrushes while addressing oral health disparities worldwide.
For Omer, the journey is far from over. His focus remains on scaling impact, expanding accessibility, and continuing to innovate at the intersection of health and sustainability.

A Story of Resilience and Reinvention
Omer Elrayah’s story is one of resilience, purpose, and transformation. From his early days in Sudan to his role as a Harvard instructor and founder of a pioneering oral care brand, his path reflects a commitment to challenging norms and creating meaningful change.
RemoBrush stands as a testament to that vision—a product rooted in tradition, driven by innovation, and designed for a better future.
In redefining oral care, Omer is not just building a brand—he is reshaping an industry and inspiring a global shift toward healthier, more sustainable living.
