#1 It may hurt your heart
People with gum disease are almost twice as likely to suffer from coronary artery disease compared to those don’t have periodontitis. Researchers aren’t exactly sure of why this might be, but one theory is that harmful bacteria from your mouth enters your blood stream and attaches to fatty plaques in your heart’s blood vessels, leading to inflammation and upping your risk of clots that can trigger heart attacks.
#2 Your memory could suffer
Some research suggests there may be a tie between poor oral health and an increased risk of dementia. One study that followed 118 nuns between the ages of 75 and 98 found that those with the fewest teeth were most likely to suffer dementia. Experts think oral bacteria may spread to the brain through cranial nerves that connect to the jaw or through the bloodstream, and may contribute to the type of plaque that’s been linked to Alzheimer’s.
#3 It can hurt blood sugar
People with diabetes are more likely to have periodontal disease than those without diabetes. While this may be because diabetics are more susceptible to infections, there’s also been research that finds gum disease could make it harder to control your blood sugar, and that treating it helps improve diabetes symptoms.
#4 It may affect breathing
Gum disease may increase your risk of getting respiratory infections, such as chronic obstructive pulmonary disease (COPD) and pneumonia, according to the Journal of Periodontology. The infections might be caused when bacteria from the mouth are inhaled into your lungs, possibly causing your airways to become inflamed.
#5 It could hurt your fertility
Women of childbearing age with gum disease took an average of just over seven months to become pregnant—two months longer than the average of five months that it took women without gum disease to conceive, discovered researchers in Western Australia. Other research finds that pregnant women with gum disease might have higher odds of miscarriage.
