Most of us accept the modern dental narrative without question..

We brush, we floss, we visit the dentist twice a year. And yet..

Why are crowded teeth so common?

Does oral health affect systemic health? How?

About the Author

David Walsh explores why modern cavities are prevalent while ancient skulls show few. His journey into gut health and the microbiome reveals insights into our dental evolution. The Primal Dentist is a platform for sharing this vital research.

What did the human mouth evolve with before processed food, antiseptic mouthwash, and toothpaste that reads like an industrial chemistry manual?

Primal Dentist explores oral health through an ancestral, biological lens, starting from the idea that the mouth is not separate from the body or from the environment we evolved in. Our genes have changed very little in 20,000 years, but our food, habits, sleep, and breathing have changed dramatically. The modern mouth reflects that mismatch.

This is not an anti-dentistry website, and it's not a place for fear or miracle cures. It's a space for curious readers who value nuance, evidence, and intellectual honesty.
