Dental care during pregnancy: what's safe and what to expect
Pregnancy hormones affect your gums, and morning sickness affects your teeth. Regular dental care is part of a healthy pregnancy.
Yes, checkups, cleanings and needed treatment such as fillings are safe during pregnancy. Many people find the second trimester a comfortable time for treatment. Hormone changes make gums more likely to swell and bleed, so cleanings matter. Tell your dental team you're pregnant. Cosmetic treatments like whitening are usually postponed until after the baby arrives.
How pregnancy affects your mouth
- Pregnancy gingivitis: gums can become red, puffy and bleed easily, often from the second month
- Pregnancy tumours: harmless red lumps on the gums that usually shrink after delivery
- Morning sickness: stomach acid can soften enamel
- Cravings and frequent snacking: more sugar contact raises the risk of cavities
- Dry mouth or extra saliva, both of which are common
Is dental treatment safe?
Routine dental care is safe and recommended during pregnancy. Local anaesthetics commonly used in dentistry are considered safe. Treating a cavity or infection is generally better than leaving it, because infection and pain affect your overall health.
Dental X-rays use a very small dose of radiation aimed at the mouth. If an X-ray is needed to diagnose a problem, it can be taken safely, and the dentist may use a protective apron. Routine X-rays are often postponed until after delivery.
Elective cosmetic treatment, such as whitening, is usually left until after pregnancy and breastfeeding.
Timing your visits
Book a checkup and cleaning early in your pregnancy if you're due for one. Many people find the second trimester, roughly weeks 14 to 27, the easiest time for longer treatment. Late in the third trimester, lying back can be uncomfortable, so short visits and a pillow or wedge under your right hip can help. Let the team know if you need to change position or take a break.
Looking after your teeth at home
- Brush twice a day with a fluoride toothpaste and floss daily, even if your gums bleed
- After vomiting, rinse with water or a mix of water and a teaspoon of baking soda; wait about 30 minutes before brushing
- If brushing makes you gag, use a small-headed brush and a mild-flavoured toothpaste
- Choose water, milk, cheese, vegetables and fruit for snacks
- Tell your dentist about any medications or supplements you're taking
After the baby arrives
The months after birth are busy, and dental visits often slip. If treatment was postponed during pregnancy, book a checkup once you're ready. Dental local anaesthetic and most common dental treatments are compatible with breastfeeding; tell the dentist if you're nursing so they can choose suitable medications.
This is also a good time to plan your baby's dental care. Wipe your baby's gums with a clean, damp cloth, start brushing when the first tooth appears, and book a first dental visit by their first birthday.
Frequently asked questions
Should I tell the office I'm pregnant?
Yes. Let us know how far along you are, any pregnancy complications and the medications you take. It helps the dentist plan safe care.
Can I have a filling while pregnant?
Yes. Needed fillings can be done during pregnancy, usually with local anaesthetic. Many people find the second trimester a comfortable time.
Are my baby's teeth affected by my oral health?
Healthy habits during pregnancy set the stage for your family. Cavity-causing bacteria can be passed from parent to baby, so treating your own cavities helps.
Will my bleeding gums go away after delivery?
Pregnancy gingivitis often improves after the baby is born. Book a checkup if bleeding or swelling continues.
