Meet the world’s oldest practicing dentist — still serving his community.
Dr. Etsuro Watanabe was born in 1924 and began his dental journey as a teenager in Japan. After serving as a medic during World War II, he returned home determined to care for his community through dentistry.
In 1953, he opened his clinic and became the only dentist in his town. For decades, he treated generations of families — often handcrafting dentures himself — building not just smiles, but lifelong trust.
Recognized by Guinness World Records, he continues to see patients even past 99 years of age. His routine is simple: morning practice, afternoon gardening, disciplined lifestyle.
His message is clear: purpose keeps you active. And for him, dentistry was never just a profession — it was service.
