Along with non-celiac gluten sensitivity (NCGS), these disorders present with multiple intestinal and extra-intestinal symptoms leading to multisystemic involvement, with complications documented in the oral cavity as well. Persistent immune activation and dysregulation, chronic inflammation, nutrient deficiencies, xerostomia, and microbial dysbiosis found in CD and NCGS constitute shared pathological findings, providing biological plausibility for an association with periodontitis. Methods: A narrative literature review was conducted based on a systematic search of four databases (PubMed, Scopus, Web of Science, Cochrane Library) and the gray literature through January 2026. A comprehensive set of clinical, radiographic, biochemical and immunological parameters was assessed. Two reviewers independently screened and selected studies, with disagreements resolved by consensus. Results: A total of 15 studies met the eligibility criteria and were included in the review. Available evidence, mainly derived from cross-sectional observational studies, remains limited, methodologically heterogeneous, and largely inconclusive. Across adult and pediatric populations, findings do not consistently demonstrate a clinically meaningful association between CD or NCGS and periodontal inflammation, irrespective of gluten-free diet (GFD) adherence. Observed differences, when reported, are modest and inconsistent, and can be mainly attributed to oral hygiene behaviors and dental visit patterns. Conclusions: Despite considerable biological plausibility linking gluten-related disorders with periodontal inflammation, current evidence does not support a definitive conclusion regarding the impact of CD or NCGS on periodontal health.<\/jats:p>","DOI":"10.3390\/jcm15082828","type":"journal-article","created":{"date-parts":[[2026,4,8]],"date-time":"2026-04-08T11:41:18Z","timestamp":1775648478000},"page":"2828","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Periodontal Status of Patients with Celiac Disease and Non-Celiac Gluten Sensitivity: A Literature Review"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-4828-284X","authenticated-orcid":false,"given":"Thaleia","family":"Angelopoulou","sequence":"first","affiliation":[{"name":"School of Medicine, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6966-7183","authenticated-orcid":false,"given":"Yiorgos A.","family":"Bobetsis","sequence":"additional","affiliation":[{"name":"Department of Periodontology, School of Dentistry, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"141","DOI":"10.1097\/MPG.0000000000002497","article-title":"European Society Paediatric Gastroenterology, Hepatology and Nutrition Guidelines for Diagnosing Coeliac Disease 2020","volume":"70","author":"Husby","year":"2020","journal-title":"J.
