Dr. Poppe

Dr. Tokiko Poppe of Cosmos Dentistry in Bellevue, Washington, considers herself incredibly fortunate to work in dentistry because she gets to witness and participate in the lives of her patients. She believes early intervention and knowledge sharing are vital to preventing oral disease and achieving lasting oral and overall health. Dr. Poppe approaches dentistry with a whole-body perspective, understanding that oral health is often closely connected to broader wellness concerns.

Dr. Poppe graduated from the University of the Pacific’s Arthur A. Dugoni School of Dentistry in San Francisco and also holds a Japanese dental license. Fluent in both Japanese and English, she proudly offers multilingual care to serve a diverse patient community. She remains deeply committed to continuing education, regularly enrolling in advanced courses and participating in both local and national study groups.

During her academic career, Dr. Poppe was involved in craniofacial research, with a focus on cleft lip and palate. She went on to complete a General Practice Residency in California, where she treated medically complex adults at a Veterans Hospital and provided care for children under general anesthesia at a University Medical Center.

Dr. Poppe continues to expand her clinical expertise and has completed all courses at Spear Education. Her passion for dentistry extends beyond patient care—she is actively involved in organized dentistry as a board member, where she contributes to the education and mentorship of other dental professionals. She maintains memberships with organizations, including the ADA, AAGO, AAPMD, WSDA, SKCD, AGD, American Laser Study Club, TBI Ambassadors, ABDSM and PNGSC.

In addition to her extensive training, Dr. Poppe is a Diplomate of the American Board of Dental Sleep Medicine (D.ABDSM), a distinction that reflects advanced expertise in treating sleep-related breathing disorders, such as obstructive sleep apnea. This specialized knowledge allows her to offer patients non-invasive, airway-focused solutions that can improve sleep quality, overall health, and daily well-being—further supporting her comprehensive, whole-body approach to care.

Dr. Poppe gains energy from her relationships with her patients and her team at Cosmos Dentistry. Outside the office, she enjoys spending time with family and friends, reading, exploring nature, and practicing yoga and Pilates. She shares her home with a Balinese cat named Gumi and a Goldendoodle named Winnie, both of which bring her great joy.
