Patient question
Is it safe to get a root canal while pregnant?
Quick answer
Yes — a root canal is safe during pregnancy, and an untreated infection is the real risk to avoid. The American Dental Association and ACOG agree that necessary dental treatment, local anesthesia, and a shielded dental X-ray are safe in pregnancy. The second trimester is the most comfortable time for elective treatment, but an active infection should be treated whenever it occurs. Leaving a dental infection untreated poses a greater risk to you and your baby than the root canal does.

The short version from the medical guidelines
Both the American Dental Association (ADA) and the American College of Obstetricians and Gynecologists (ACOG) state clearly that preventive and necessary dental care — including root canals — is safe and should not be delayed during pregnancy. An untreated dental infection carries real risks, and treating it removes a source of infection and pain.
What about the X-ray?
A dental X-ray uses a very small dose of radiation, aimed at your mouth and far from the abdomen, and we use a lead apron with a thyroid collar for additional shielding. The radiation dose to the fetus from a dental X-ray is negligible. ACOG specifically states that X-rays needed for diagnosis are safe in pregnancy. We still take only the images we genuinely need.
What about the anesthetic and medications?
- Local anesthetic: lidocaine is routinely used and considered safe in pregnancy. We use the appropriate type and amount for your stage of pregnancy.
- Pain relief: acetaminophen is the preferred pain reliever in pregnancy. Ibuprofen and other NSAIDs are generally avoided, particularly in the third trimester — always confirm with your OB.
- Antibiotics: if one is needed, several (such as penicillin-class antibiotics) are well-established as safe in pregnancy.
- Sedation: elective sedation is generally deferred during pregnancy; most root canals need only local anesthesia anyway.
The best timing
The second trimester (weeks 14–27) is the most comfortable window for non-urgent treatment — early-pregnancy nausea has usually settled and you can still lie back comfortably. That said, an active infection or significant pain should be treated whenever it happens, in any trimester. The goal is never to leave an infection brewing while waiting for the perfect window.
Why not just wait until after delivery?
Because an untreated infected tooth doesn't pause for nine months. Dental infections cause pain, stress, and difficulty eating, and the infection itself is a risk. Pregnancy also tends to worsen gum inflammation, so a smoldering problem often gets worse, not better. Treating the source promptly is the safer, more comfortable path.
How we handle pregnant patients
We coordinate with your OB whenever there's any question, position you comfortably (often slightly on your left side later in pregnancy to keep pressure off the major blood vessels), keep appointments efficient, and choose medications matched to your trimester. Let us know you're pregnant — and how far along — when you call: (669) 234-2354.
Related questions
Is a dental X-ray dangerous for my baby?
No. The dose is tiny, directed at your mouth, and we shield your abdomen and thyroid with a lead apron. ACOG confirms that dental X-rays needed for diagnosis are safe during pregnancy. We still take only the images necessary to treat you safely.
Which trimester is best for a root canal?
The second trimester (weeks 14–27) is the most comfortable for non-urgent treatment. But an active infection or significant pain should be treated in any trimester — delaying treatment of an infection is riskier than the procedure itself.
What pain medicine can I take while pregnant?
Acetaminophen is the preferred option in pregnancy. Ibuprofen and other NSAIDs are usually avoided, especially in the third trimester. Always confirm any medication with your OB, and tell us you're pregnant so we prescribe accordingly.
Is the numbing injection safe during pregnancy?
Yes. Lidocaine, the standard dental local anesthetic, is routinely used and considered safe in pregnancy. Being properly numb also reduces stress, which is good for both you and your baby. We tailor the type and amount to your stage of pregnancy.
Should I just wait until after I give birth?
Not for an infection or active pain — those should be treated promptly because an untreated infection is a greater risk than the treatment. A truly elective, asymptomatic procedure could sometimes wait, but most teeth needing a root canal shouldn't be left untreated for months.
