Is a Root Canal Safe During Pregnancy?
Necessary dental treatment, including root canal treatment, is generally considered safe during pregnancy and should not be delayed when there is infection, pain, or another problem that needs care. Major bodies emphasize that dental care in pregnancy is safe and important. Elective work is often scheduled in the second trimester for comfort, but urgent problems are addressed promptly at any stage, coordinated with the prenatal provider.

Is a root canal safe during pregnancy: the short answer
Pregnancy raises a natural question: if a tooth is painful or infected, is it safe to have it treated now, or should treatment wait until after the baby is born? The reassuring answer from major bodies is that needed dental care, including root canal treatment, is generally considered safe during pregnancy and is part of looking after both parent and baby. The deciding factor is usually the dental problem itself, not the pregnancy, and care is coordinated with the prenatal provider.
Necessary dental treatment, including root canal treatment, is generally considered safe during pregnancy and should not be delayed when there is infection, pain, or another problem that needs care. The American College of Obstetricians and Gynecologists emphasizes that dental care during pregnancy is safe and important, and that poor oral health has been linked to adverse pregnancy outcomes (ACOG 2013). The local anesthetics used in dental treatment have not been shown to meaningfully increase birth defects or other adverse outcomes in available data (Hagai et al. 2015). Dental X-rays, when needed, are taken with abdominal and thyroid shielding (National Consensus 2012). Elective procedures are often scheduled in the second trimester for comfort, but urgent problems should be addressed promptly at any stage, in coordination with the prenatal care provider (ACOG 2013; National Consensus 2012).
What the evidence says
The guidance that dental care during pregnancy is safe is not a single opinion — it comes from obstetric and dental bodies together, and it is supported by outcome data on the local anesthetics used in dental treatment. The points below summarize what those sources actually say.
Major bodies treat needed dental care as safe and important
- The American College of Obstetricians and Gynecologists states that dental treatment during pregnancy is safe and important, and recommends an oral health evaluation at the initial prenatal visit — American College of Obstetricians and Gynecologists 2013.
- Poor oral health has been linked to adverse pregnancy outcomes, which is part of why maintaining and restoring oral health is encouraged rather than postponed — American College of Obstetricians and Gynecologists 2013.
- A national consensus statement from obstetric and dental organizations advises providing needed dental care during pregnancy and not delaying urgent conditions, in coordination with prenatal care — National Consensus Statement 2012.
What the data show about local anesthetics
- In a prospective cohort, the rate of major anomalies after dental treatment with local anesthetics was not significantly different from unexposed pregnancies (4.8% vs 3.3%, P=0.30) — Hagai et al. 2015.
- That same study found no difference in miscarriage, gestational age at birth, or birth weight, and endodontic treatment was the most common dental procedure in the exposed group (about 43%) — Hagai et al. 2015.
- The authors concluded that dental treatment with local anesthetics is not a major teratogenic risk and that there is no reason to withhold it when treatment is needed — Hagai et al. 2015.
Radiographs and positioning when needed
- When dental X-rays are needed for diagnosis, they are taken with abdominal and thyroid shielding — National Consensus Statement 2012.
- Later in pregnancy the enlarging uterus can press on the vena cava, so a slight position change (such as a small left tilt) may make the chair more comfortable — National Consensus Statement 2012.
- Imaging is used only when it is needed to guide care, not routinely, and the prenatal provider is kept informed — National Consensus Statement 2012.
Anesthetics: no major risk signal

Timing and practical points
Beyond the question of safety, a few practical points shape how dental care is timed and delivered during pregnancy. The table below summarizes the common ones; the right approach for an individual is set by the treating clinician together with the prenatal provider.
01Timing (elective vs urgent)Elective procedures are often scheduled in the second trimester for comfort, while urgent problems such as infection or significant pain are addressed promptly at any stage.

Medication choices during pregnancy — including any pain relief or antibiotics — are individualized and are decided by the treating clinician together with the obstetric provider; this page does not provide specific drug or dose recommendations.
Why not just wait?
It can feel safer to put off a procedure until after delivery, but leaving a dental infection or significant pain untreated has its own risks. Deferring needed care is not automatically the safer choice, which is why the guidance is to treat what needs treating and coordinate the timing rather than simply wait.
Why deferring needed care is not automatically safer
- An untreated tooth infection generally does not resolve on its own and can persist or worsen while care is postponed — American College of Obstetricians and Gynecologists 2013.
- Poor oral health has been linked to adverse pregnancy outcomes, so leaving active disease untreated is not a neutral choice — American College of Obstetricians and Gynecologists 2013.
- Significant dental pain and the stress and poor sleep that come with it are themselves worth addressing rather than enduring through the pregnancy — American College of Obstetricians and Gynecologists 2013.
Emergency: when to seek urgent care now
Fever with facial swelling, swelling that is spreading quickly, swelling near the eye or down into the neck, or any difficulty breathing or swallowing can be signs of a serious, spreading infection. Seek urgent or emergency care immediately and tell the team you are pregnant — do not wait for a routine appointment.
Choosing to treat versus wait, and the timing of any procedure, is decided together with the treating dentist and the obstetric or prenatal provider for the individual pregnancy.

04
What trimester is best for dental work?
Short answer
Elective procedures are often scheduled in the second trimester, mainly for comfort and easier positioning.
- 01Urgent problems such as infection or significant pain are addressed promptly at any stage rather than postponed (National Consensus 2012).
- 02Your dentist and obstetric provider can advise on timing for your pregnancy.
05Can I wait until after the baby is born?
05
Can I wait until after the baby is born?
Short answer
Elective treatment can sometimes be timed around the pregnancy, but an active infection or significant pain is generally not something to leave untreated.
- 01An untreated tooth infection usually does not clear on its own, and poor oral health has been linked to adverse pregnancy outcomes (ACOG 2013), so deferring needed care is not automatically the safer option.
- 02Discuss the timing with your dentist and obstetric provider.
06What about a tooth infection while pregnant?
06
What about a tooth infection while pregnant?
Short answer
A tooth infection during pregnancy is generally treated promptly rather than left to wait, because it tends not to resolve on its own and can worsen.
- 01Seek a dental evaluation, and seek urgent care for fever, rapidly spreading facial swelling, or difficulty breathing or swallowing.
- 02Tell the team you are pregnant so care can be coordinated with your obstetric provider.
