This document summarizes several studies that demonstrate the relationship between oral health and overall health. Multiple studies found that tooth loss is associated with atherosclerotic plaque buildup in arteries. Periodontal treatment was shown to improve outcomes for patients with diabetes such as blood sugar control and inflammation. Higher levels of C-reactive protein, a marker for cardiovascular disease, were found in people with periodontal infections or periodontitis. Reducing oral biofilm through practices like brushing, flossing and using xylitol was shown to reduce inflammatory markers and potentially help conditions like COPD. The document advocates for reducing oral biofilm and increasing access to dental hygienists to improve overall health and save on medical costs.
