During the nine months of pregnancy, there are likely a million things that are on your mind at any given moment. In early pregnancy, your primary focus might just be making it through the day without succumbing to morning sickness, or making it to your next ultrasound appointment. As the months go on, heartburn, back pain, and constipation might be on your list of pregnancy discomforts.

Something you might not be thinking at all about during pregnancy is your oral health. Believe it or not, your teeth and gums can be affected by pregnancy. In fact, 60 to 75 percent of pregnant people have oral health issues like gingivitis during their pregnancy, according to a report by CareQuest Dental Health Institute. And in the worst case scenario, untreated gum disease can lead to complications like preterm birth or low weight.

We definitely don’t want that to happen, so we spoke to dental experts to find out why pregnancy may cause oral health changes and how to take extra precautions when taking care of your teeth and gums while you’re pregnant.

Why does pregnancy cause you to be more susceptible to gum disease?

Pregnancy hormones are the culprit of many of the changes you have during the three trimesters, including morning sickness, and it turns out it can be a culprit of morning sickness, too. “The body’s rising levels of hormones like estrogen and progesterone during pregnancy can cause sensitive teeth or swollen and inflamed gums, which can sometimes lead to pregnancy gingivitis. If left untreated, it can cause tooth decay and enamel erosion, as well as impact the baby,” explains Dr. Victoria Veytsman, DDS, Philips Sonicare Partner.

However, there will be some preliminary signs of gingivitis, the precursor to full-blown periodontal disease, before it gets to that severe point, so don’t worry. Some people have gingivitis before they get pregnant, and it persists throughout pregnancy or gets worse with all the inflammation. Other people may notice gingivitis red flags like swollen, red, or bleeding gums when brushing their teeth for the first time during pregnancy, says Schelli Stedke, dental hygienist and care advisor at Dentistry.One. “In combination with that, people may have gastric upset and are feeling poorly, which makes it harder to clean their mouth or get motivated to take care of any part of their body,” Stedke adds. The vomiting often associated with morning sickness can coat the teeth with acid, potentially eroding the teeth and leading to cavities and decay.

So how can this impact the baby? More research still needs to be done, but severe gum disease during pregnancy could lead to poor birth outcomes, including premature birth or low birth weight. This is possibly because gingivitis begins as an infection of gum tissue, but can progress to the more serious form of gum disease, periodontitis, that could involve bloodstream infections that eventually affect the baby, Stedke explains. It is also possible to pass along cavity-causing bacteria from parent to child in simple ways like sharing a spoon or straw, since infants aren’t naturally born with that type of bacteria, according to Stedke.
