In this episode of Dentistry Disrupted, Dr. Craig Clayton is joined by his personal functional medicine provider and friend, Lyndsy Kinghorn. Lyndsy is a dual board-certified nurse practitioner in family and anti-aging medicine and the founder of Foundation Functional Medicine in Boise, Idaho. Together, they explore the powerful overlap between functional medicine and functional dentistry—and how collaborating across disciplines can radically transform patient care.

Lindsay shares her journey from ER nurse practitioner and competitive athlete to passionate functional medicine provider after her own unresolved health symptoms led her to seek deeper answers. She breaks down the key differences between traditional and functional medicine, emphasizes the importance of root cause resolution, and highlights the limitations of “normal” lab ranges.
