Why Women with PCOS Have 3x More Gum Disease (And What It Means for Your Hormones)

In this episode of Hormone Heroines, we sit down with Christine Horton — women's health coach, dental hygienist, and Programs and Advocacy Co-Director for the PCOS Awareness Association — to explore the surprising link between oral health and hormone balance.

Christine, who was diagnosed with PCOS at 17 and later navigated insulin resistance and a difficult perimenopause, walks us through the recent renaming of PCOS to PMOS (Polyendocrine Metabolic Ovarian Syndrome) — a shift meant to capture the condition's true whole-body, lifelong nature rather than framing it as a fertility issue alone.

We dive into the oral-systemic connection: how inflammation in the mouth can enter the bloodstream and influence conditions like cardiovascular disease, diabetes, and pregnancy outcomes. Christine explains the difference between reversible gingivitis and irreversible periodontitis, and why this relationship is bi-directional — oral care can improve A1C, while hormonal shifts can inflame the gums even without any change in habits.

Women with PMOS, Christine notes, face roughly 3x the rate of periodontal disease due to elevated androgens, insulin, and baseline inflammation. The conversation closes with practical, hopeful guidance: get a baseline check with your doctor and dentist, protect one non-negotiable source of daily joy, and take a closer look at the personal care products you use every day.

Christine Horton is a women's health coach, dental hygienist, and founder of Fusion Health Coaching, where she bridges medical, dental, and lifestyle care for a true whole-person approach. She serves as Programs and Advocacy Co-Director for the PCOS Awareness Association and lives with PCOS/PMOS herself, bringing personal insight to her work supporting women through diagnosis, insulin resistance, and perimenopause.
