Why do some people develop cavities despite taking excellent care of their teeth—and could tooth decay begin years before a cavity becomes visible?

This free introductory guide by Dr Alex Cornell explores tooth decay from a Medical Medium–informed perspective, looking beyond the conventional sugar-and-acid explanation to introduce six underlying factors that may contribute to weakening teeth over time, including mineral deficiencies, digestive health, harmful bacteria, stress and plaque.

You’ll also find seven practical steps to support teeth and learn when early demineralisation may be able to remineralise—and when dental treatment may still be necessary.

A simple starting point for understanding the root-cause approach to tooth decay. For detailed protocols, oral-healing foods, supplements, oral hygiene recommendations and a much deeper exploration of dental health, see my comprehensive guides and upcoming book, Dental Deliverance.
