"Our understanding of the importance of pathogenic microbes to oral health is important because the three main oral diseases—dental caries, periodontitis, and oropharyngeal cancer—begin with an underlying microbial dependence."

"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.
