Dental Care During Pregnancy: What Is Safe?

Why pregnancy affects your teeth and gums

Hormone changes during pregnancy — particularly the rise in progesterone and estrogen — increase blood flow to the gums and make gum tissue more reactive to the bacteria in dental plaque. This is why many pregnant people notice that their gums bleed more easily when brushing or flossing, a condition called pregnancy gingivitis. If existing plaque and inflammation go untreated, this can progress to periodontitis, a more serious gum infection.

Some people also develop pregnancy granulomas (sometimes called "pregnancy tumors") — benign, reddish lumps on the gum tissue that bleed easily. These almost always resolve after delivery.

Acid from morning sickness can also erode enamel over time. Rinsing with water or a diluted baking-soda solution after vomiting (rather than brushing immediately) helps protect the softened enamel.

Is it safe to go to the dentist while pregnant?

Yes — and professional guidelines actively recommend it. The American College of Obstetricians and Gynecologists and major dental organizations agree that routine preventive care (exams, cleanings) should continue throughout pregnancy 1Ref 1American College of Obstetricians and Gynecologists (2020).Tobacco and Nicotine Cessation During Pregnancy: ACOG Committee Opinion, Number 807.ACOG recognizes oral health as part of comprehensive prenatal care and recommends dental visits continue during pregnancy.

The second trimester is generally considered the most comfortable time for elective dental work — morning sickness has usually settled, and lying in a dental chair for longer is easier than it will be in the third trimester. That said, urgent treatment (a painful infection, a broken tooth) should not be postponed regardless of trimester. An untreated dental abscess can spread and poses a real risk.

Are dental X-rays safe during pregnancy?

Routine bitewing X-rays deliver very low radiation doses, and modern digital systems deliver even less. Most dentists defer non-urgent X-rays during pregnancy as a precaution, but if X-rays are needed to diagnose pain or infection, they can be taken safely with a lead apron over the abdomen. The risk of an undiagnosed or untreated dental problem typically exceeds the minimal radiation exposure from a necessary X-ray.

Which dental procedures are safe — and which should wait?

Generally safe throughout pregnancy: - Routine cleanings and scaling (especially important given pregnancy gingivitis) - Local anesthetic (lidocaine with epinephrine is considered safe at standard doses) - Fillings to treat cavities - Emergency extractions or root canals for infection - X-rays when clinically necessary, with lead apron

Best deferred to after delivery if non-urgent: - Elective cosmetic procedures (whitening, veneers) - Elective extractions of asymptomatic teeth - Extensive planned treatment that is not urgent

Medications to discuss with your provider: Some antibiotics used in dentistry (amoxicillin, clindamycin) are considered safe in pregnancy; others (tetracyclines) are not. Your dentist should know you are pregnant so they can choose appropriately. For pain after procedures, discuss options with your dentist and your obstetric provider — the landscape for OTC pain management in pregnancy has changed in recent years.

What about sedation and nitrous oxide?

Nitrous oxide (laughing gas) is generally avoided during pregnancy, particularly in the first trimester, due to concerns about exposure in the early weeks of development. If you need sedation for a dental procedure, let your dentist know you are pregnant so they can discuss the options with your obstetric provider and choose the safest approach. For most routine dental work, local anesthetic alone is sufficient.

How to protect your teeth during pregnancy

• Brush twice daily with fluoride toothpaste 2Ref 2Walsh T, Worthington HV, Glenny AM, Marinho VCC, Jeroncic A (2019).Fluoride toothpastes of different concentrations for preventing dental caries.Fluoride toothpaste twice daily is effective for preventing dental caries
• Floss daily — bleeding gums during pregnancy usually improve with consistent flossing, not an excuse to stop
• If morning sickness is severe, ask your dentist about a fluoride rinse or prescription fluoride treatment
• Schedule a cleaning in the second trimester if you haven't had one
• Tell your dentist and your obstetric provider about each other — coordinate care for any planned procedures
• Eat a balanced diet and stay hydrated; pregnancy cravings for sugary foods can increase cavity risk

Gum disease and pregnancy outcomes

Research has explored a possible link between periodontitis and adverse pregnancy outcomes such as preterm birth and low birth weight 3Ref 3Smiley CJ, Tracy SL, Abt E, Michalowicz BS, John MT, Gunsolley J, Cobb CM, Rossmann J, Harrel SK, Forrest JL, Hujoel PP, Noraian KW, Greenwell H, Frantsve-Hawley J, Estrich C, Hanson N (2015).Evidence-based clinical practice guideline on the nonsurgical treatment of chronic periodontitis by means of scaling and root planing with or without adjuncts.Background on periodontitis and evidence for treating gum disease, relevant to pregnancy context. The exact nature of this relationship remains under investigation, but it underscores why maintaining good oral health during pregnancy is not simply cosmetic — it is part of overall prenatal care. Treating gum disease during pregnancy does not harm the pregnancy and may be beneficial.

This is a topic to raise with both your dentist and your OB or midwife so your care is coordinated.

Gale is not a dental provider — for dental cleanings, exams, or treatment you will need to see a dentist. Gale can help you prepare questions for your dental visit, talk through how to discuss your pregnancy with your dental team, or connect you with your primary care or OB provider if you have questions about medications or general prenatal health.
