Is there a link between Diabetes & Periodontal Disease?

For decades multiple studies have been done showing the link between these two diseases, time and again a strong correlation has been found. The severity of periodontal disease increases with poor glycemic control and blood sugar levels are more difficult to regulate in individuals with periodontal disease. Oftentimes described as a complication of diabetes. So let’s take a look at each of these diseases, how they affect the other and why preventive care is so important.

Untreated periodontal disease can cause fluctuation in blood glucose.

Periodontal Disease
As we discussed in a previous post, periodontal disease is the inflammation and destruction of gingival tissue and the bone supporting our teeth. Occuring in about 50% of American adults, periodontal disease is fairly common, and is number one cause of tooth loss in adults.

Diabetes Mellitus
Diabetes is a chronic systemic illness affecting about 10% of American adults and another 35% are prediabetic. There’s a misconception that diabetes only affects blood sugar levels. The reality is it either directly or indirectly affects all the body organs and their functions. 

The Link
The correlation between the aforementioned diseases appears to go both ways. Severe periodontal disease accounts for about 10-15% of cases. Severe disease was found to be prevalent in around 60% of Diabetic patients as compared to 39% in non-diabetics.  Studies have shown that adults with diabetes have lower  immune responses. This makes them more susceptible to general infections, including but not limited to periodontal disease. A common symptom of  diabetes is poor wound healing, which makes periodontal disease treatment less predictable. Poor collagen synthesis and impaired production of bone cause weakened gum tissue, ligaments and bone supporting the teeth. 

 We are now more aware that uncontrolled diabetes increases the risk for periodontal disease, now to look at the reverse. Severe periodontal disease increases blood sugar levels and increases the time an individual spends with higher blood sugar.  With this effect on blood sugar; it is harder to gain control and keep levels stable.

In order to maintain control of diabetes, regular testing of blood sugar is imperative.

In summary, the link here has been vastly studied and nearly always results in a negative impact of one disease on the other. Prevention is key and maintaining good oral hygiene can help keep a good grasp on glycemic control. Also, having a close relationship with your physician to keep your HbA1c below 7% is imperative to decreasing your risk of severe periodontal disease.
