Pregnancy
It is common for pregnant women to experience bleeding, swollen and painful gums; another condition that may also develop is a "pregnancy tumor," which is a benign growth that usually shrinks when the pregnancy is over. It is extremely important for pregnant women to practice regular and efficient oral hygiene to minimize these symptoms. There is some research that suggests that periodontal disease can result in pre-term deliveries and/or low birth-rate babies.
