Good oral hygiene not only gives us a positive impression, it is also a reflection of our state of health. An imbalance of oral bacteria dominated by bad bacteria not only cause tooth decay, tooth loss and periodontal diseases, it can even lead to cardiovascular diseases. Numerous research studies have shown a connection between heart disease and key bacteria in periodontal disease. The bacteria from oral diseases can enter the bloodstream and travel to the arteries in the heart and cause inflammation which lead to atherosclerosis (hardening of the arteries). Atherosclerosis narrows the blood flow through the body. This can cause an increased risk of heart attack or stroke. Bacteria from gum disease can also cause lung infection.
Besides that, approximately 95% of Americans who have diabetes also have periodontal disease and research shows that people with periodontal disease have more difficulty controlling their blood sugar level.
A recent study discovered that the presence of certain bacteria in the mouth may increase the risk of pancreatic cancer. According to researchers from NYU Langone Medical Center, New York University School of Medicine, people with Porphyromonas gingivalis in their oral microbiomes had an overall 59 percent greater risk of developing pancreatic cancer than those without this bacteria in their microbiomes. Similarly, individuals with Aggregatibacter actinomycetemcomitans in their oral microbiomes were at least 50 percent more susceptible to developing the disease. Both types of bacteria are associated with periodontitis (inflammation of the gums).
