Is it true that gum disease can cause premature labor?


If your gum disease is severe enough then yes, you could face an increased risk of preterm labor. According to research, women who suffer from periodontal disease are 7 times more likely to deliver prematurely. Do not confuse gum disease with pregnancy gingivitis (swelling, bleeding, redness or tenderness in the gums that is triggered by hormones) which tends to show up around the second or third month of pregnancy and tends to increase in intensity until around the eight month. Note: you may want to switch to a softer toothbrush to minimize the bleeding.
