The mouth is the gateway to the body and it is not a sterile one. Periodontal disease (gum disease) is a quiet, devastating infection caused by bacteria in the mouth that can also infect the body’s integral systems. These include the heart, lungs, kidney, liver and even the joints and connective tissue. Dr. Eddie Longman of Alexandria Old Town Dental asserts, “The most important thing to do if you have gum disease is to slow it down and then work on getting it stopped.”
