Mapping the Microbiome: The Mouth–Sleep Connection

In this powerful episode of Beyond Breathing, host Lancette VanGuilder takes you on a deep dive into the fascinating world of the microbiome—your mouth’s hidden ecosystem—and how it shapes your gums, your gut, your brain, and your sleep. September is National Gum Care Month, and with nearly 47% of U.S. adults affected by gum disease, there’s no better time to understand how your oral health connects to your airway health and your entire body.

Lancette unpacks how mouth breathing, sleep apnea, dysbiosis, and dry mouth all disrupt the delicate microbial balance in your mouth. She also explores how dental hygienists, dental therapists, and dentists are at the frontlines of prevention—offering salivary testing, airway evaluations, and annual sleep screenings that can transform your health from the inside out.

🔑 What You’ll Learn in This Episode

• Dry Mouth & Mouth Breathing: How these habits lead to dysbiosis, increased cavities, and disrupted sleep.
• Oral–Gut–Brain Microbiome Link: How microbes travel from your mouth to your gut and even your brain, influencing inflammation, cognition, mood, and sleep quality.
