Oral and dental health in patients with diabetes mellitus (DM) requires special attention due to the bidirectional relationship between diabetes and oral health. Individuals with diabetes are more susceptible to oral health problems such as periodontal (gum) disease, dental caries (cavities), fungal infections like oral thrush, and delayed wound healing. These conditions can be exacerbated by poorly controlled blood glucose levels, which compromise the body’s ability to fight infections and heal tissues. Periodontal disease, in particular, is prevalent among diabetics and can worsen glycemic control, creating a vicious cycle that impacts overall health. Conversely, oral infections and inflammation from poor oral hygiene can contribute to insulin resistance, potentially aggravating diabetes management. Effective management of oral health in diabetes includes regular dental check-ups, meticulous oral hygiene practices (brushing, flossing, and using mouthwash), and timely treatment of dental issues. Dentists play a critical role in educating patients about the importance of oral hygiene and monitoring for early signs of oral complications. Collaborative care between dental and medical professionals is essential to ensure comprehensive management of both diabetes and oral health, thereby improving overall quality of life and reducing the risk of systemic complications.
