“If you make one investment in your health this entire year, let this be it. The mouth is the gateway to your body and oral bacteria have been associated with a higher risk for systemic conditions including Alzheimer’s, diabetes, cardiovascular disease, and poor pregnancy outcomes.

You can’t be healthy without a healthy mouth. And what you don’t measure, you cannot manage.”
