Dr. Jared Helfant: Is Your Toothpaste Killing You? The Dangers of "Nuking" Your Mouth Bacteria | Sleep Apnea, Jaw Development & The Truth About Fluoride

Andrés Preschel Episode 151

Did you know that using strong mouthwash might be destroying your blood pressure and gut health? In this episode, Andres sits down with Dr. Jared Helfant, a functional dentist who is changing the way we look at oral health. They dive deep into why the "kill 99% of bacteria" approach is outdated and how maintaining a symbiotic oral microbiome is the key to systemic health.

Dr. Helfant breaks down the critical difference between nasal and mouth breathing, explaining how the latter ruins facial structure, sleep quality, and nitric oxide production. They also uncover a shocking connection between childhood ADHD diagnoses and undiagnosed sleep airway issues. From the impact of soft foods on jaw development to the debate between fluoride and nano-hydroxyapatite, this episode is packed with actionable advice to optimize your airway, sleep, and smile.

Key Topics Discussed:

  • The Functional Approach: Why dentistry should not be treated separately from the rest of the medical system.
  • The Oral Microbiome: Why you should stop trying to "kill" all bacteria in your mouth and how to test your oral flora.
  • Mouth vs. Nasal Breathing: The physiological disasters caused by mouth breathing, including changes in facial structure and increased cortisol.
  • Nitric Oxide: How nasal breathing and specific foods (like beets) fuel this vital molecule for blood pressure and sexual health.
  • The ADHD Misdiagnosis: Why 60-70% of kids diagnosed with ADHD might actually be suffering from sleep apnea and airway obstruction.
  • Jaw Development: How breastfeeding and chewing hard foods influence the skeletal structure of the face.
  • Sleep Apnea Solutions: Moving beyond the CPAP—using palate expanders and mandibular advancement devices to fix the root cause.

Actionable Tips:

  • Test, Don't Guess: Consider using services like Bristle to test your oral microbiome.
  • Chew Your Food: Encourage children to chew harder foods to promote jaw expansion.
  • Stop the Snore: If you or your partner snore, get a sleep study that looks at oxygen depletion, not just stoppages in breathing.
  • Ditch the Nukes: Swap harsh antimicrobial mouthwashes for products that promote symbiosis.
