Driven by a personal loss of his grandmother to oral cancer, Dr. Bibhakar Ranjan devoted his career to raising awareness on oral health, particularly among cancer patients, pregnant women, and underserved communities. His innovative approaches — including the use of sound and music therapy to ease dental anxiety — reflect his unique combination of medical expertise and yoga knowledge.

In 2022, he was recognized among the World’s Top 100 Doctors by the Global Summit Institute (USA) for his contributions to preventive oral healthcare. He currently serves as the International Ambassador and Continental President of the Dental AI Association (DAIA), leading efforts to incorporate AI technology into modern dentistry.

In 2024, Dr. Ranjan coined the term “Ozempic Mouth” to describe a cluster of oral symptoms observed in patients using semaglutide (Ozempic). The term has since been referenced by medical experts and media outlets, recognizing Dr. Ranjan’s role in identifying and naming the phenomenon.

Looking beyond Earth, Dr. Ranjan is deeply committed to pioneering space dentistry — a field critical to the future of long-duration space missions and human colonization of other planets such as Mars. His goal is to make dental hygiene in space simple, safe, and enjoyable, ensuring future space travelers and colonies maintain optimal oral health without discomfort or risk.

In 2025, Dr. Ranjan expanded his mission of service beyond healthcare and into public life, running for the Beirat  für Migration und Integration election in Unkel, Germany. His campaign focuses on building bridges between cultures, amplifying migrant voices, and creating stronger, more united communities.

Beyond clinics, conferences, and now the campaign trail, Dr. Ranjan shares his mission of health and holistic wellness through his podcast Dr. Ranjan Speaks and his upcoming children’s book on overcoming dental phobia. His life’s work is centered on a profound belief: to heal smiles, inspire minds, and pioneer health innovation — from Earth to outer space.
