INSIGHT

Teeth Are Built From The Inside

Teeth are built from nutrients delivered by the bloodstream and depend on vitamin D3 and K2 to mineralize properly.
Tooth decay often reflects nutrient deficiency and poor diet, not just external sugar exposure.

INSIGHT

Mouth Microbiome Shapes The Gut

The mouth is the body's entrance and hosts a highly diverse oral microbiome that shapes gut microbes.
Oral microbes change within 12–24 hours with diet, so front-door microbiome health affects the whole gut.

ADVICE

Chew Whole Foods To Strengthen Teeth

Chew real, single-ingredient foods to strengthen teeth, jaws, and saliva production through mechanical loading.
Favor meat, fish, eggs, raw carrots and other whole foods over soft ultra-processed items.
