Some women get swollen and sore gums, which may bleed, during pregnancy. Bleeding gums are caused by a build-up of plaque on the teeth. Hormonal changes during pregnancy can make your gums more vulnerable to plaque, leading to inflammation and bleeding. This is also called pregnancy gingivitis or gum disease.
Pregnancy tumors are benign tumors — they are not cancerous — and they show up on the gums of up to 5 percent of pregnant women. Pregnancy tumors are generally raised, well-defined nodules between 0.5 and 2.5 centimeters in size. Some women find them painful; others don't notice any pain.
Because pregnancy tumors are often caused by the hormonal changes in a pregnant woman's body, they often disappear after the baby is born, according to the ADA.
Pregnancy granuloma occurs in 5% of pregnant women. It is indistinguishable from pyogenic granuloma, and is a rapidly growing, tumor-like lesion that develops as a response to local irritation such as poor hygiene, overhanging restorations, or trauma.
