SPIT:
How the Secrets of the Oral Microbiome Could Save Your Life
by Staci Whitman
Crown Trade, spring 2027

Dr. Staci Whitman’s SPIT explores the oral microbiome as a critical, yet often ignored, driver of whole-body health. Bringing her pioneering work in functional dentistry to the forefront, she connects oral health to major systems in the body, from the heart and hormones to digestion and immunity. With a dynamic blend of science, storytelling, and cultural insight, the book reframes the mouth as a powerful ecosystem that can influence everything from chronic disease to overall vitality.

If GUT opened the door and BREATH ushered readers into an entirely new understanding of the body, then SPIT delivers the next big idea in wellness. This is a surprising and essential book about one of the most overlooked yet powerful ecosystems in the human body.

Dr. Staci Whitman is a powerhouse. A trailblazer in functional dentistry, a board-certified pediatric dentist, and one of only a handful of IFM-certified practitioners in her field, she is an entrepreneur, innovator, and educator with a vision to make the world cavity-free. She has founded the first pediatric functional dental practice in the United States, launched two health-focused product lines, and is leading the development of the first certification program that trains dentists to treat oral health through a systemic lens. She is also earning a master’s degree in functional medicine and nutrition while treating patients and building a national education platform. Her energy is remarkable. Her clarity and purpose are inspiring.

Dr. Staci is also a savvy, strategic, and ambitious partner. With over 200K followers across platforms and a robust email list, she’s intentionally investing in growing her audience further and is hiring a dedicated social growth strategist in advance of publication. She’s already appeared on Andrew Huberman’s podcast and is receiving interest from the biggest names in the podcasting world—from the Joe Rogan Experience to Mel Robbins, Dr. Mark Hyman, Liz Moody, and Max Lugavere.

What is most exciting, though, is the quality and originality of the work. SPIT is a beautifully written, deeply researched, and wildly entertaining journey into a realm of science most people have never considered. This is not just a book about brushing your teeth better. It is about how the oral microbiome connects to inflammation, heart disease, hormonal balance, the brain, digestion, sleep, immunity, and even fertility. With a warm, witty, and thoroughly accessible voice, Dr. Staci blends cutting-edge science, patient stories, and cultural history to show readers how their mouths can be the key to their health and vitality. It is timely, important, and full of potential.

Dr. Staci Whitman is the co-founder of The Institute for Functional Dentistry, an allied partner of The Institute for Functional Medicine. She’s pioneering the first certification program that trains dentists in the oral-systemic connection. She founded Bloom Kids Dentistry in Portland, Oregon, the first functional pediatric dental practice in the U.S., with national expansion underway. This practice takes a whole-body, holistic approach to dentistry, grounded in science and driven by compassion. Dr. Staci is also an entrepreneur, creating Happi Floss (the world’s first truly sustainable floss pick) and co-creating Fygg (Feed You Good Guys), an oral healthcare line dedicated to protecting and supporting the oral microbiome. She earned her DMD from Tufts University School of Dental Medicine and later completed a pediatric dentistry certification at Oregon Health and Science University, where her research focused on improving airway assessments in children. A Diplomate of the American Board of Pediatric Dentistry since 2012, she’s a Board-Certified Pediatric Dentist and a Fellow of the American Academy of Pediatric Dentistry.
