Abstract

GLP-1 receptor agonists (GLP-1RAs) are associated with improved periodontal health through multiple mechanisms.

Better glycemic control, weight loss, and reduced inflammation may contribute to the positive effects of GLP-1RAs on periodontal health.
GLP-1RAs may directly influence tissue health through GLP-1 signaling pathways.
Preclinical studies indicate that GLP-1RAs can reduce inflammation, osteoclast activity, and alveolar bone loss.
Improved function of periodontal stem cells under conditions of hyperglycemia or inflammation has been observed with GLP-1RAs.
Animal studies suggest potential osteometabolic benefits from GLP-1RA use in implant practices.
Limited human data indicate that GLP-1RA therapy may modify periodontal risk and healing capacity rather than serve as a primary treatment.

Simplified

GLP-1 receptor agonists (GLP-1RAs) are widely used in the treatment of type 2 diabetes and obesity and are increasingly relevant in periodontal and implant practice. This review covers mechanisms, preclinical and early human evidence, and practical periodontal considerations; the structured database search is conducted in accordance with the Scale for the Assessment of Narrative Review Articles (SANRA) and the International Committee of Medical Journal Editors (ICMJE) principles. Two pathways explain GLP-1RAs' relevance: indirect effects from better glycemic control, weight loss, and reduced inflammation; and direct tissue effects involving GLP-1R signaling and the GLP-1/dipeptidyl peptidase-4 (DPP-4) axis. Preclinical studies show reduced inflammation, osteoclast activity, and alveolar bone loss, along with improved periodontal stem cell function under hyperglycemia or inflammation via Nuclear Factor-kappaB (NF-kappaB), Wingless-related integration site (Wnt)/beta-catenin, and Mitogen-Activated Protein Kinase (MAPK) pathways. Animal studies on implants and local delivery, including exendin-4 platforms, suggest osteometabolic benefits. Human data are limited and mostly observational, and confounders include metabolic status, smoking, medication, and nutrition. Oral side effects such as xerostomia and dehydration are also noted. At present, GLP-1RA therapy should be regarded as a contextual modifier of periodontal risk and healing capacity rather than as a stand-alone periodontal therapy.
