What Most People Get Wrong About Oral Health (and How to Fix It)

Most people think brushing is just about teeth and breath. But according to Dr. Staci Whitman, a board-certified functional pediatric dentist, your mouth is the gateway to your brain, hormones, and long-term health.

In a conversation with Dr. Andrew Huberman, she breaks down how oral hygiene is linked to inflammation, heart health, cognitive decline—and even your hormones.

🔍 Why the Mouth Matters (More Than You Think)

Inflammation in the gums spreads quietly through the bloodstream, contributing to:

• 🧠 Alzheimer’s and cognitive decline

• ❤️ Heart disease

• 🧬 Hormonal disruption

• 🦷 Tooth decay, bad breath, and jaw issues

• And even developmental issues in kids

✅ ACTIONABLE TAKEAWAYS

1. Brush at the Gumline

• Use a soft-bristled brush at a 45° angle to clean where the tooth meets the gum.

• Brush twice daily, ideally with an electric toothbrush.

2. Try Nano-Hydroxyapatite Toothpaste

• 🦷 Helps remineralize enamel and reduce sensitivity

• 👶 Safe for kids and adults

• 🧪 Bonus: It’s biomimetic—it rebuilds tooth structure in a way the body recognizes

Look for brands that include “nHA” or nano-hydroxyapatite” on the label.

3. Floss Daily (Yes, It’s Still Essential)

• Removes plaque where your brush can’t reach

• Linked to lower systemic inflammation, heart health, and brain protection

4. Clean Your Tongue Every Morning

• Use a metal scraper or soft toothbrush

• Helps prevent bad breath and supports gut health

5. Prioritize Nasal Breathing

• Nasal breathing increases saliva flow and helps maintain healthy mouth pH

• Consider mouth taping at night if you’re a mouth breather or snore

6. Use Fluoride with Intention (or Not at All)

• If using fluoride, keep it minimal and don’t swallow

• If avoiding fluoride, nHA is an excellent replacement that dentists like Dr. Whitman support

🧬 Hidden Impact: Hormones and the Mouth

Oral inflammation may:

• Suppress testosterone in men

• Disrupt estrogen balance in women

• Affect libido, fertility, and mood

🧠 Final Thought

Start with your mouth. It might be the simplest way to protect your brain, your hormones, and your long-term health.
