Dental health can be a tricky balancing act for women who are pregnant. Not only are they more susceptible to a variety of oral health problems, but some of those issues (and their treatment) may put their developing baby at risk.

It is safe for pregnant women to undergo necessary dental X-rays and other dental procedures like root canals. In fact, it is often much more dangerous to delay these procedures if they are needed to treat an immediate oral health issue.

If you’re pregnant, it’s important to maintain your oral hygiene routine, eat tooth-friendly foods and take certain precautions to counteract the effects of your pregnancy. Once your baby is born, you should also take steps to set them up for good oral health for life.

Why Dental Health Changes During Pregnancy

Hormonal changes during pregnancy have a big impact on your oral health, especially your gums. They may become extra sensitive, bleed more easily than usual and develop benign growths that can look alarmingly like cancer. All of these changes are common, and they usually recede over time.

If you experience morning sickness during your pregnancy, you may also find yourself vomiting much more often than usual. This can create an acidic environment in your mouth, which is bad for your teeth. 

Nutrition also plays a role in dental health during pregnancy. If you don’t get enough calcium from your diet to support the growth of your baby, your body will take what they need from your blood, bones, and teeth. This can cause permanent damage to your teeth.

General Oral Health Tips 

Oral Health Issues Pregnancy May Cause

To maintain good oral health during pregnancy, you should:

  • Continue to brush twice a day for at least two minutes each time and floss daily. 

  • Eat a healthy diet. Make sure you and your baby get all of the nutrients you need while avoiding foods with added sugars. 

  • Sip water often to hydrate your mouth, wash away food particles, and deliver small doses of fluoride to your teeth. 

  • If you have morning sickness, rinse your mouth with water immediately, then wait 30 minutes. Once this time is up, brush your teeth to make sure you’ve gotten rid of all the acid in your mouth.  

  • Consider taking a calcium supplement to ensure you have enough calcium in your body for both you and your child.

Are X-Rays Safe?

Dental X-rays are safe when you are pregnant, but you should subject yourself to them as little as possible.

Although the radiation dosage from X-rays is low, it nonetheless is an exposure. While carrying your baby, you should limit any radiation your baby will be exposed to.

Your dentist will use a leaded apron to cover your torso during your X-ray to protect you and your baby. This will absorb most of the harmful radiation, but repeated exposures will add up over time.  

If you are worried about the impact of X-rays on your baby, talk to your dentist. He or she can tell you more about the risks involved and what might happen if you don’t get the X-ray. You can then make an informed decision about whether you want to proceed.

Root Canals and Other Major Procedures

According to the UT Southwestern Medical Center, pregnant patients can undergo medically necessary dental procedures at any point during their pregnancy without fear of being unsafe.

Some dentists may recommend that certain procedures be delayed until after the first trimester or after the baby has been delivered. However, this depends on the urgency of the problem that needs to be treated.

The second trimester is considered to be the safest time for a pregnant patient to get fillings, to have a root canal and to undergo other major dental procedures. If you are anxious about getting dental care while pregnant, it is a good idea to schedule a checkup between the third and sixth months of your pregnancy.

Oral Health Issues That Pregnancy May Cause

Pregnancy can cause a number of various oral health problems, including:

Pregnant women often experience cravings for sweet food items. This may lead them to consume a lot of sugar at many points throughout the day, eventually resulting in tooth decay.

Morning sickness vomiting produces acid in your mouth. This acid can wear away at the enamel on your teeth and make them more vulnerable to breakage and decay.

An estimated 60-75% of pregnant women have gingivitis, which can quickly develop into periodontitis. Periodontitis in pregnant women has been linked to poor birth outcomes like low birth weight and preterm birth.

Some pregnant women develop small round growths on their gums as a result of the hormonal changes they are experiencing. These growths can look a lot like oral cancer, but they are benign and can easily be removed by your dentist or oral surgeon.


Many organizations have developed various resources to help pregnant women maintain good oral health and care for their baby’s developing teeth.

Dental Care for Your Newborn 

Once your child is born, you will also need to care for their teeth. Here are some tips to help you do this. 

  • Wipe your child’s gums with a soft cloth twice a day, just like you would brush their teeth. This keeps your baby’s mouth clean and prevents cavities from forming while their teeth are breaking through their gums.

  • If you give your baby a bottle in their crib at night, do not offer them anything but water. Milk, juice, and other liquids contain sugars which may put any developing teeth at risk. 

  • Once your baby’s first tooth comes in, brush their teeth twice a day using a smear of toothpaste about the size of a grain of rice. 

  • Bring your baby to the dentist for their first checkup by their first birthday. This is a critical time for spotting developing problems like early tooth decay or impacted baby teeth.
