Cavities Are Not Just About Sugar - The Functional Dentistry Approach to the Oral Gut Brain Connection | Gut | E120

What if cavities are not just about brushing and flossing, but a signal of microbiome imbalance and diet patterns?

In this episode, Dr. Aaron Hartman sits down with Dr. Staci Whitman, DDS, to break down what functional dentistry really means and why oral health is never “just teeth.” Dr. Whitman explains how ultra processed foods, frequent snacking, and an acidic oral environment drive cavities through microbiome imbalance, and why many early cavities can be remineralized or arrested when you catch them in time. They also explore the oral gut brain connection, why gum inflammation can become systemic inflammation, and how airway issues like mouth breathing and narrow palates can impact sleep, behavior, and long term health, especially in kids.
