There are more chances of developing oral infections in diabetes, primarily because of increased blood sugar. Sugar acts as a very good medium for the growth of bacteria, hence if proper oral hygiene is not maintained it can lead to oral infections such as periodontal disease (infection of gums and the surrounding structures), gingivitis (infection of gums), or fungal infections.
A data of 4,300 type 2-diabetes patients (in the age group of 45-90 years) has shown that patients with poorly controlled blood sugar are at an increased risk of developing periodontal disease, which can ultimately lead to loss of teeth. In fact, it was observed that the risk was nearly 3 times more in inadequately controlled diabetes as compared to well-controlled diabetes.
Hence, an efficient blood sugar control and proper oral hygiene is a must for all diabetic patients. If you have diabetes, make it a point to brush and floss your teeth regularly, and visit a dentist at least once in 2 years.
