Dental Care During Pregnancy: What Is Safe and Why It Should Not Wait

Is dental treatment safe during pregnancy?

The American College of Obstetricians and Gynecologists (ACOG) states that prevention, diagnosis and treatment of dental problems, including needed X-rays and local anaesthetic, are safe during pregnancy¹. It adds that extractions, root canal treatment and fillings for decay may be managed at any time during pregnancy, and that delaying treatment may result in more complex problems. This is a committee opinion from 2013, reaffirmed in 2025; it carries no formal evidence grade.

For gum treatment in particular, a European and American expert consensus found that treating gum disease in pregnancy has been shown to be safe and improves the gums².

You may have heard that dental work should wait for the middle three months of pregnancy. None of the guidance cited here makes that a rule. Pain, infection or a broken tooth should be seen when they happen.

Local anaesthetic, X-rays and painkillers

Local anaesthetic

ACOG includes local anaesthetic among the care that is safe in pregnancy. The evidence from patients is limited. The main study followed 210 pregnancies in Israel in which the mother had dental local anaesthetic, 112 of them in the first three months, and compared them with 794 pregnancies without such exposure. Major birth defects were found in 4.8% and 3.3%³ respectively, a difference that was not statistically significant. There was also no difference in miscarriage, length of pregnancy or birth weight. The authors concluded that dental local anaesthetics do not represent a major risk of birth defects. This is a single study, and a difference that is not statistically significant does not prove the rates are the same. It concerns local anaesthetic only: if you might need sedation or a general anaesthetic, discuss it separately with your dentist and your doctor.

X-rays

Dental X-rays are aimed at the mouth, not the abdomen. UK guidance says that for almost all dental X-ray views, including panoramic and 3D (CBCT) scans, there is no requirement to delay radiography⁴ until after the birth, and that dentists should offer pregnant patients the option of postponing X-rays that are not urgent. A systematic review concluded that dental imaging in pregnant women should not be restricted if clinically indicated⁵, while noting that few studies have looked at safe thresholds.

Advice on lead aprons and thyroid collars differs between expert bodies. ACOG's 2013 opinion mentions shielding the abdomen and thyroid. The UK guideline asks for abdominal protection only in the rare views where the baby would be in the X-ray beam. A 2023 American radiology recommendation advises no longer using fetal or thyroid shields⁶ for dental X-rays. If you have a preference, discuss it with your dentist.

Painkillers

The NHS says that paracetamol can be taken during pregnancy⁷, and that you should avoid ibuprofen during pregnancy unless a doctor or pharmacist advises it.

Clove oil is often suggested for toothache. The European Medicines Agency's herbal monograph does not recommend it in pregnancy or breastfeeding⁸.

Gum changes in pregnancy

Bleeding gums are common in pregnancy. A review of 20 studies found bleeding when the gums were gently probed in about 67 in 100 pregnant women⁹, with large differences between studies, and bleeding tended to increase as pregnancy went on. ACOG, summarising review articles, describes pregnancy gingivitis as making the gums swell and bleed more easily in most women, typically peaking in the last three months.

What helps:

• Keep brushing twice a day with fluoride toothpaste, gently along the gum line, even where it bleeds.
• Clean between your teeth every day.
• ACOG notes that rinsing with warm salt water may help with the irritation. This is a comfort measure, not a treatment.
• Have your gums checked. Bleeding that does not settle may be more than pregnancy gingivitis. How gum disease is treated is explained on the gum disease treatment page.

Pregnancy tumour (epulis). Some women develop a red, swollen growth on the gum, usually on the gum at the front of the mouth. ACOG, citing review articles, says it appears in approximately 5% of pregnancies¹, usually goes away after the birth, and rarely needs removal unless it causes severe pain, bleeding or problems with eating. ACOG lists it among benign gum lesions, but any lump in the mouth should be looked at by a dentist.

Does gum disease affect the baby?

The link. Studies that observe pregnant women find that those with periodontitis, gum disease that has damaged the bone around the teeth, have somewhat more premature births. Bleeding gums on their own do not mean you have periodontitis. A 2026 review of 11 such studies found, with moderate certainty, a small increase in the risk of premature birth¹⁰, and taking other factors into account made the risk smaller. An earlier expert consensus described the links with premature birth, low birth weight and pre-eclampsia as modest and varying² between populations. An observed link does not show that gum disease causes these outcomes.

Does treatment prevent premature birth? Not clearly. In a Cochrane review, 11 trials with 5,671 women compared premature birth between women who had gum treatment in pregnancy and those who did not, and found no clear difference¹¹, based on low-quality evidence. A 2026 review of 14 trials with 8,316 women concluded that treatment may reduce the risk¹² at moderate certainty, but its result is also compatible with no effect.

So the reason to treat gum disease in pregnancy is the health of your gums and teeth, which treatment does improve, and not a promise about the birth.

You may read that gum disease causes miscarriage or gestational diabetes. None of the sources we checked supports that.

When to see a dentist

Make an appointment, and mention that you are pregnant, if you have:

• toothache, a broken tooth or a lost filling
• gums that bleed when you brush or eat hard food¹³, or are painful or swollen
• a routine check-up due: you do not need to skip it because you are pregnant

Ask for an urgent appointment if your gums are very sore and swollen, a tooth becomes loose, or you have a lump in your mouth or on your lip¹³. Toothache with swelling of the gum, face or jaw, or with a fever, also needs an urgent appointment: a dental abscess needs urgent treatment by a dentist¹⁴ and will not go away on its own. Pregnancy is not a reason to wait.

Emergencies. Call 112 or go to the nearest emergency department if you:

• find it hard to breathe, speak or swallow¹⁴
• have a swollen or painful eye, sudden problems with your eyesight, or swelling in your neck¹⁵
• have a lot of swelling inside your mouth
• find it hard to open your mouth
