Diabetes and the Mouth–Body Axis: A Two-Way Street of Health and Disease

The connection between diabetes and oral health is bidirectional and profound. Poorly controlled diabetes increases susceptibility to periodontal disease, dry mouth, infections, and delayed wound healing. In turn, periodontitis and oral inflammation worsen insulin resistance and glycemic control, amplifying systemic risk. This eBook explores the biological mechanisms linking diabetes and oral disease, from immune dysregulation to microbiome shifts. Patients will gain a clear understanding of why managing oral health is crucial in diabetes care and how targeted strategies—from periodontal therapy to lifestyle interventions—can improve both metabolic control and overall longevity.
