Diabetes And Periodontal Disease

Diabetes is a serious, incurable disease that is characterized by too much glucose, or sugar, in the blood. Type II diabetes occurs when the body is unable to regulate insulin levels, meaning too much glucose stays in the blood. Type I diabetics cannot produce any insulin at all. Diabetes affects between 12 and 14 million Americans, and can lead to a variety of health issues, such as heart disease and stroke.

Research has shown people with diabetes are more likely to develop periodontal disease than non-diabetics. Diabetics with insufficient blood sugar control also develop periodontal disease more frequently and severely than those who have good management over their diabetes. 

The connection between diabetes and periodontal disease results from a variety of factors. Diabetes sufferers are more susceptible to all types of infections, including periodontal infections, due to the fact diabetes slows circulation, allowing bacteria to colonize. Diabetes also reduces the body’s overall resistance to infection, which increases the probability of the gums becoming infected.

Moderate to severe cases of periodontal disease elevate sugar levels in the body, increasing the amount of time the body has to function with high blood sugar. Diabetics with periodontitis are most likely to suffer from increased levels, making it difficult to keep control of their blood sugar. Further, high glucose levels in saliva promote growth of gum disease-causing bacteria.

Blood vessel thickening is another concern for diabetics. Blood vessels function by providing nutrients and removing waste products from the body. When they become thickened by diabetes, these exchanges are unable to occur. As a result, harmful waste is left in the mouth and can weaken the resistance of gum tissue, leading to infection and disease.

Smoking and tobacco use is detrimental to anyone’s oral and overall health, but it is particularly harmful to diabetics. Diabetic smokers 45 and older are in fact 20 times more likely to develop periodontal disease than those who do no smoke.

It is very important for everyone to brush teeth effectively, floss daily, and visit the dentist regularly, but it is especially essential that diabetics practice these measures. When teeth are left un-brushed, harmful bacteria can ingest the excess sugar and colonize beneath the gum line.
