What about dentinal fluid flow?

Not to hijack this thread, but I've had this in the back of my mind for quite some time...

According to Dr. Steinman's research findings, while external contamination does affect the tooth, tooth decay starts when normal tooth metabolism is upset and fluid flow is interrupted, impeded, stagnating or even reversed. As the flow can be self-cleansing, it can also be self-contaminating. Dr. Steinman identified several pathways for this to occur, among them

• High sugar intake reverses dentinal fluid transport
• Stress can interrupt dentinal fluid transport
• Lack of exercise
• Lack of micronutrients
• Pharmacological agents

What does Curezone think?
