It is very common for pregnant women to have swollen, red gums that bleed when brushing their teeth or using dental floss.
More than half of expectant mothers experience these symptoms, a condition known as pregnancy gingivitis. It can progress to inflammation due to hormonal changes that make the gums more sensitive to plaque bacteria.
A benign growth may also develop on your gums that bleeds when you brush your teeth. This relatively rare lump is called a pregnancy tumor or pyogenic granuloma — it may sound frightening, but it is harmless and usually painless. It typically disappears after childbirth, but if it persists, it should be removed. If it causes discomfort when chewing or brushing, or if it begins to bleed excessively, it can be removed during pregnancy. It is therefore important to take good care of your teeth and gums during pregnancy.
