Aim: This paper explores the relationship between obesity and oral diseases. Early detection and prevention of risk factors are essential for indispensable for promoting long-term health and elevating the quality of life in affected patients. Materials and methods: A search of PubMed and Google Scholar on November 10, 2024, retrieving 48 articles from 2016-2024. After screening criteria, 45 articles were included. All authors verified the final content. Conclusions: Evidence suggests a notable association between obesity and oral health issues, including periodontitis, peri-implantitis, and other gum diseases. Certain research point to the possibility that patients who undergo bariatric surgery could also experience worsening dental health. Inadequate oral hygiene and excessive sugar consumption, along with obesity, contribute to the worsening of dental problems in both children and adults. Further studies are required to better elucidate the underlying mechanisms of this association, which remains insufficiently explained in literature.
