Dentists will take extra precautions when they know you’re pregnant to ensure your care is safe for you and your baby.

Causes of dental health problems
Common causes of dental health problems during pregnancy can include:
- hormone changes
- cravings for sugary foods
- gagging while brushing teeth.
Hormone changes and gum problems
Pregnancy hormones can make some women be at risk of gum problems including:
- gingivitis (inflammation of the gum) – this is likely to occur during the second trimester. Symptoms include swelling of the gums and bleeding, mostly during brushing and when flossing between teeth
- periodontal disease – infection of the structures supporting the tooth (gums, ligament and bone). It’s caused by untreated gingivitis and can lead to tooth loss
- pregnancy epulis or pyogenic granuloma – a red, round growth that appears on the gum, which can bleed easily.
If you have gum problems during pregnancy, it’s important to get them checked by a dentist before you give birth. While most types of gum problems caused by pregnancy hormones resolve after birth, a small number of women may develop ongoing gum disease that will need treatment after pregnancy.
If your gums bleed, don’t stop cleaning your teeth. Continue to use a soft-headed toothbrush and fluoride toothpaste to brush at least twice a day and clean between your teeth with floss or interdental brushes.
Vomiting can damage teeth
Pregnancy hormones soften the ring of muscle that keeps food inside the stomach. (regurgitating food or drink) or the vomiting associated with can cover your teeth with strong stomach acids. Repeated reflux and vomiting can damage the surface of the tooth (the enamel) and increase the risk of decay.
Try these suggestions if you’re experiencing vomiting:
- Avoid brushing your teeth immediately after vomiting. While the teeth are covered in stomach acids, the actions of brushing may scratch the tooth enamel.
- Rinse your mouth thoroughly with plain tap water.
- Follow up with a mouthwash containing fluoride.
- If you don't have a fluoridated mouthwash, put a blob of toothpaste containing fluoride on your finger and smear it over your teeth. Rinse thoroughly with water.
- Wait for an hour after vomiting before you brush.
If you experience recurrent severe vomiting, speak to your doctor or obstetrician about other strategies to manage your symptoms.
Retching or gagging while brushing teeth
Some pregnant women find that brushing their teeth, particularly the back teeth, can cause gagging. However, it’s important to brush all of your teeth to avoid tooth decay.
Some tips to help prevent gagging include:
- Use a toothbrush with a small soft head, such as a brush made for toddlers.
- Take your time. Go slowly when you brush.
- It may help to close your eyes and concentrate on your breathing.
- Try listening to music.
- If the taste of the toothpaste causes you to gag, switch to another brand. Or brush your teeth with water and then use a mouthwash containing fluoride. Go back to brushing with toothpaste containing fluoride as soon as you can.
Food cravings while pregnant

If nothing but sweetness will satisfy your craving, try to sometimes choose healthier options, such as fresh fruit. Rinse your mouth with mouthwash containing fluoride or brush your teeth after having sugary snacks. If your cravings continue, speak to your dentist about preventive treatments and other products containing calcium or fluoride which may offer you more targeted protection.
