Diabetes can have a significant impact on oral health due to high blood sugar levels. People with diabetes are at a higher risk for gum disease, tooth decay, and dry mouth. High glucose can lead to infections in the gums and mouth, making it crucial to maintain good oral hygiene. Brushing twice a day, flossing, and regular dental check-ups are essential. Additionally, controlling blood sugar levels can help reduce the risk of oral health problems. The NHS emphasizes the importance of oral health care for individuals with diabetes.
