Healthy dietary habits, including avoiding a caloric surplus, may be beneficial to oral and systemic health. Further, specific macronutrients and micronutrients may enhance periodontal health and healing. Periodontal diseases are microbially-induced diseases that are propagated by host-mediated inflammation that results in disease progression and loss of periodontal tissues. The interaction between nutritional intake and the overall host inflammatory state may allow for improved outcomes with modification of dietary intake. In some instances, dietary changes and/or vitamin or mineral supplementation may improve outcomes for patients with periodontal diseases.
