What is the link between diabetes and sensitive teeth?

Gum disease cause sensitive teeth. Gum disease appears to be more frequent and more severe among those with diabetes. Conversely, it appears that treating gum disease in people with diabetes can help improve blood sugar control.

There is no direct connection between diabetes and sensitive teeth. However, when diabetes is poorly controlled, levels of blood glucose (sugar) can remain high; this can exacerbate serious gum disease. As diseased gums pull away from the teeth, the cementum layer on the roots is readily worn away, leaving the underlying dentin exposed, and sensitive teeth result. Gum disease can progress from the early stage of gingivitis to more serious conditions, such as periodontitis; eventually, people with untreated periodontitis can lose their teeth from chronic gum infection and inflammation. Periodontitis can cause further problems for people with diabetes, who need their teeth in order to follow a healthy diet. Research has shown that it may even be more difficult for diabetics to control their blood glucose if they have periodontitis.
