If blood glucose is not well controlled over a long period, complications such as diabetic peripheral vascular disease and diabetic peripheral neuropathy may develop. These complications reduce blood supply around the teeth, leading to a series of problems, including periodontal infection, shortened tooth lifespan, and atrophy of periodontal salivary glands.
Specifically, a long-term state of high blood glucose creates a favorable environment for periodontal bacteria to grow, which easily causes periodontal infection and gingivitis. Meanwhile, diabetic patients may experience gum recession, loose teeth, and even tooth loss, which affect appearance and normal chewing.In addition, abnormal periodontal microcirculation can lead to atrophy of periodontal salivary glands and reduced saliva secretion, resulting in indigestion and a higher risk of dental caries.
Therefore, diabetic patients need to actively control their blood glucose.If complications or tooth‑related problems occur, they should seek medical attention promptly to check whether the dental lesions are related to diabetic complications.After confirming the cause, targeted treatment should be carried out under the guidance of a doctor.
