The Influence of Diet and Physical Activity on Periodontal Health: A Narrative Review.

Periodontal diseases, including gingivitis and periodontitis, are chronic inflammatory conditions that compromise the supporting structures of the teeth, often leading to tooth loss and contributing to systemic comorbidities. Increasing evidence underscores the critical role of modifiable lifestyle factors, particularly diet and physical activity, in influencing periodontal health. This narrative review critically evaluates the current body of literature regarding the impact of dietary constituents and physical activity on the periodontium, with a focus on the molecular mechanisms, key biomarkers, and clinical implications. It aims to provide a deeper understanding of the complex interactions between nutrition, exercise, and periodontal health with potential implications for clinical management and preventive strategies.
