Dental Care During Pregnancy: What's Safe and What to Watch For
Pregnancy hormones can make gums swell and bleed. Learn why dental check-ups are safe and recommended during pregnancy and how to protect your teeth.
Quick answer
Dental check-ups, cleanings and needed treatments such as fillings are safe during pregnancy, and the second trimester is often the most comfortable time. Hormone changes make gums more likely to swell and bleed (pregnancy gingivitis). Brush twice a day with fluoride toothpaste, clean between teeth, and after vomiting rinse with water instead of brushing straight away. Always tell your dentist you are pregnant.

Pregnancy changes the mouth as well as the body. Keeping up dental care protects your health, and good habits help your baby's future oral health too.
Common changes in pregnancy
- Pregnancy gingivitis: swollen, red gums that bleed easily
- Pregnancy epulis: a harmless red swelling on the gum that usually disappears after birth
- Enamel erosion from frequent vomiting with morning sickness
- Cravings for sugary snacks, raising the risk of decay
Is dental treatment safe during pregnancy?
Yes. Professional bodies including the American College of Obstetricians and Gynecologists and the American Dental Association agree that preventive care, cleanings, dental X-rays with appropriate shielding when needed, and treatments such as fillings with local anaesthetic are safe during pregnancy. Delaying needed treatment can be riskier than having it.
The second trimester is often the most comfortable time for routine treatment. Always tell your dentist you are pregnant and which medicines you take.
Looking after your teeth
- Brush twice a day with fluoride toothpaste, and clean between teeth daily.
- After vomiting, rinse with water or a fluoride mouthwash and wait about an hour before brushing.
- Keep sugary snacks to mealtimes and choose water to drink.
- Have a dental check-up during pregnancy.
When to see a dentist promptly
- Toothache or swelling
- Gums that bleed a lot or are very painful
- A broken tooth or lost filling
Facial swelling with fever needs urgent attention.
Frequently asked questions
Can I have a local anaesthetic while pregnant?
Yes. Local anaesthetics used in dentistry are considered safe in pregnancy at normal doses.
Will my baby take calcium from my teeth?
No, that is a myth. Tooth problems in pregnancy come from gum changes, vomiting and diet, not calcium loss.
