Dr. Miller believed a dense strong tooth would “resist indefinitely” an attack from acid, whether it be from bacteria or from food. Meanwhile, a non-dense tooth would succumb quickly to any sort of acid, from bacteria or otherwise. Dr. Miller also wrote that, "The invasion of the micro-organisms is always preceded by the extraction of lime salts."12 In plain terms, the tooth loses its mineral density first (lime salts), and then microorganisms can cause trouble.
