Why It Happens

Bleeding gums is a symptom of gingivitis. According to MOH, pregnancy increases the risk of developing gingivitis and periodontitis (gum infection) due to the increase in oestrogen and progesterone. This is also known as pregnancy gingivitis. Pregnancy gingivitis can leave your gums tender and swollen while you are pregnant, which is why they often bleed when you brush and floss.

Complications

Gingivitis during pregnancy (and otherwise) is a mild form of gum disease that can progress to periodontitis, which can increase the risk of premature birth, low birth weight or preeclampsia, according to the What to Expect website. Proper oral care before, during and after your pregnancy will help to prevent these issues and keep your baby as healthy as possible during gestation and after delivery.

What You Can Do

Proper oral care during pregnancy is the best way to prevent gingivitis. Use a soft-bristled toothbrush, and brush gently twice a day; soft bristles and a gentle brushing motion prevent an excess of pressure on your gums that can lead to bleeding. Brushing roughly can exacerbate inflammation. Use toothpaste with fluoride, which is essential for healthy teeth. Make sure you floss once a day as well.

See your dentist regularly during your pregnancy. They will monitor your gums for gingivitis and will offer tips on keeping bleeding to a minimum. If you notice a lot of blood on your toothbrush or when you spit, call your dentist and let them know. They will probably schedule an appointment to rule out a more serious problem.

Limit sugary foods and those that stick to your teeth. This includes many types of candy, soft drink, juice and dessert. Make sure you're getting enough vitamin C and calcium, which are nutrients that play a big role in the health of your teeth and gums.
