For Patients

There is growing evidence that oral inflammatory diseases have an impact on systemic health conditions. Severe gum disease in the mouth can lead to destruction of the supporting structures of teeth causing loss of gums and bone. This disease has been associated with cardiovascular disease, adverse pregnancy outcomes, lung conditions, inflammatory bowel disease, Alzheimer’s disease, and diabetes. The evidence for some conditions is still growing, but it does highlight how important taking care of your mouth is for the health of your entire body.
