Dental Emergencies During Pregnancy: A Guide to Safe Care

The most common mistake made during pregnancy is not seeking treatment that turns out to be inadvisable. It is postponing treatment that should have happened.

Patients frequently tell us they waited weeks with a toothache because they assumed nothing could be done until after the birth. In most cases something could have been done, sooner, more simply, and with less discomfort. An untreated dental infection does not pause for nine months; it progresses, and the treatment required at the end of that period is usually more involved than the treatment that would have resolved it at the start.

This article sets out how urgent dental problems are managed during pregnancy, what is and is not deferred, and what to do in the meantime.

The position taken by UK dental and maternity bodies is consistent: routine dental examinations, hygiene treatment and necessary restorative care can be provided throughout pregnancy, and urgent treatment should not be delayed at any stage.

What is normally deferred is elective work — whitening, cosmetic procedures, non-urgent replacement of sound restorations — not because of established harm but because there is no reason to carry it out during pregnancy when it can equally be done afterwards.

The practical distinction is therefore between necessary and elective, rather than between safe and unsafe.

Always tell the dental team you are pregnant, how many weeks, and about any pregnancy-related complications or medications. That information changes appointment planning, positioning and prescribing.

Several changes converge to raise the likelihood of a dental problem appearing during these months.

Gum tissue becomes more reactive. Rising progesterone increases the permeability of gum capillaries and amplifies the inflammatory response to plaque. Gums that coped with an imperfect routine before pregnancy may bleed and swell during it. Our companion article on pregnancy and gum care covers this in detail.

Acid exposure increases. Morning sickness brings stomach acid into contact with enamel. Repeated exposure softens the surface, and a tooth with an existing crack or a deep restoration may become symptomatic.

Eating patterns change. Nausea, cravings and small frequent meals all increase the number of acid challenges per day. Frequency, rather than total quantity, is what drives decay risk — as covered in our article on frequent snacking and decay.

Routines slip. Fatigue, nausea triggered by toothpaste flavour or by a brush at the back of the mouth, and general disruption all make consistent cleaning harder at exactly the point when the tissues are least tolerant.

Existing problems declare themselves. A tooth that was quietly deteriorating often becomes symptomatic when any of the above is added to it.

The following warrant prompt contact rather than waiting:

• Facial or gum swelling, particularly if it is spreading, involves the eye or the floor of the mouth, or is accompanied by fever or difficulty swallowing. This requires same-day assessment. Our article on recognising a true dental emergency sets out the thresholds.

• Severe or persistent toothache, especially pain that wakes you at night or is not relieved by simple measures.

• A dental abscess or a bad taste from discharging pus. See our article on abscess symptoms and signs of infection.

• A broken tooth with exposed nerve tissue, or a tooth fractured below the gum.

• A knocked-out or displaced tooth following trauma.

• Bleeding that does not stop after an extraction or injury.

• A lost crown or filling leaving a sharp edge or exposed dentine.

• A gum lump that is enlarging, bleeding heavily or interfering with eating.

Infection is the category that matters most. A localised dental infection that spreads produces fever and systemic illness, and maternal infection is a concern in its own right. This is why urgent treatment is provided rather than deferred.

Timing within the pregnancy. The second trimester is usually the most comfortable window for planned treatment. In the first trimester nausea is often at its worst; in the third, lying back for extended periods becomes uncomfortable and can compress major vessels. None of this prevents urgent treatment at any stage — it shapes how appointments are arranged.

Positioning. From around the middle of pregnancy onwards, patients are generally treated in a semi-reclined position, often with a slight tilt to the left and support under the right hip, to avoid the weight of the uterus pressing on the vena cava. Shorter appointments with breaks are usual.

Local anaesthetic. Local anaesthesia is routinely used during pregnancy. Treating a patient without adequate anaesthesia, so that they experience pain and stress, is not the safer option. The choice of agent and whether a vasoconstrictor is included is a clinical decision taken with the pregnancy in mind.

Radiographs. Dental radiographs use a very small dose, tightly collimated to the jaw, and directed away from the abdomen. Modern digital sensors have reduced exposure further. They are not taken unnecessarily during pregnancy, but where a radiograph is needed to diagnose an infection or determine whether a tooth can be saved, it is taken with appropriate shielding. Making a treatment decision blind is the larger risk.

Medication. Prescribing is adjusted. Some analgesics and some antibiotic classes are avoided in pregnancy, others are well established in use. Paracetamol is generally the first-line analgesic; non-steroidal anti-inflammatories such as ibuprofen are usually avoided, particularly in the third trimester. Do not self-prescribe from a home medicine cabinet — check first.

Sedation. Conscious sedation is generally avoided during pregnancy other than in specific circumstances and with medical input.

Toothache from an inflamed nerve. Where the pulp is irreversibly inflamed, root canal treatment removes the source of the pain. It is routinely provided during pregnancy and is usually preferable to leaving the tooth to abscess.

Abscess. Drainage and removal of the source of infection is the priority, with antibiotics as an adjunct where there is spreading infection or systemic involvement — not as a substitute for treating the tooth.

Decay. A cavity can be restored during pregnancy. Deferring it for months allows it to progress towards the nerve, converting a filling into root canal treatment.

Broken or chipped teeth. Sharp edges can be smoothed and exposed dentine covered. Definitive cosmetic work can wait; symptom relief and protection should not.

Gum swelling. Localised gum overgrowth that appears during pregnancy — sometimes called a pregnancy epulis — is benign and often reduces after delivery, but it can be removed if it bleeds heavily or interferes with eating.

Extraction. Where a tooth cannot be saved and is causing infection, extraction can be carried out during pregnancy.

While waiting for an appointment:

• Take paracetamol at standard doses unless you have been advised otherwise, and avoid ibuprofen unless specifically told it is appropriate.

• Rinse with warm salt water for gum discomfort or after trauma.

• Keep the area clean, even if it is tender — plaque left on an inflamed site makes things worse.

• Avoid placing aspirin or clove oil directly on the gum; both can burn the soft tissue.

• Eat on the other side and avoid temperature extremes.

• If a crown has come off, keep it, and do not attempt to recement it with household adhesive.

• Seek same-day help for swelling with fever, difficulty swallowing or difficulty opening the mouth.

After vomiting, rinse rather than brush. Enamel is temporarily softened by stomach acid, and brushing immediately abrades it. Rinse with water or a fluoride mouthwash and wait around thirty minutes.

Adapt the routine to the nausea. A smaller brush head, a mild or unflavoured toothpaste, and brushing at a different time of day all help when the usual routine triggers gagging.

Clean between the teeth daily. Reactive gums respond disproportionately to small amounts of plaque.

Keep hygiene appointments. Professional cleaning during pregnancy is appropriate and is often the most useful single intervention. See our article on how often to see a hygienist.

Have an examination early. Detecting a problem at twelve weeks is considerably easier to manage than discovering it at thirty-six.

• Urgent dental treatment should not be postponed because of pregnancy; untreated infection is the greater concern.

• Routine examinations, hygiene treatment and necessary restorative care can be provided throughout.

• Elective and cosmetic work is normally deferred until after the birth.

• The second trimester is usually the most comfortable window for planned treatment.

• Local anaesthetic is used routinely; radiographs are taken when needed for diagnosis, with shielding and minimal dose.

• Prescribing is adjusted — paracetamol is generally first line, ibuprofen usually avoided.

• Tell your dental team you are pregnant and how many weeks, at the point of booking.

Can I have dental treatment while pregnant?

Yes. Examinations, hygiene treatment, fillings, root canal treatment and extractions can all be carried out during pregnancy when they are needed. Elective cosmetic procedures are generally deferred. Informing the dental team about the pregnancy allows treatment to be planned appropriately.

Can dental X-rays be taken during pregnancy?

Dental radiographs involve a very small, tightly directed dose and are not aimed at the abdomen. They are not taken unnecessarily, but where one is required to diagnose infection or plan urgent treatment it will be taken with appropriate shielding, because treating without a diagnosis carries its own risk.

What should I do about toothache during pregnancy?

Contact a dental practice rather than waiting it out. In the meantime, paracetamol at standard doses is generally appropriate, ibuprofen is usually avoided, and warm salt water rinses may ease gum discomfort. Pain that wakes you at night, or any swelling, warrants prompt assessment.

Does pregnancy cause tooth decay?

Pregnancy itself does not decay teeth. What changes is the environment: acid from morning sickness, more frequent eating, and disrupted cleaning routines. Calcium is not drawn out of the teeth by the pregnancy, despite a persistent myth to that effect.

Which trimester is best for dental work?

The second trimester is usually the most comfortable for planned treatment — nausea has often settled and lying back is still manageable. Urgent treatment is provided in any trimester.

Are antibiotics safe during pregnancy?

Some antibiotic classes are well established in pregnancy and others are avoided. Prescribing is adjusted accordingly and, where there is any uncertainty, discussed with your maternity team. Antibiotics are used alongside treatment of the source of infection, not instead of it.

If you are pregnant and have dental pain, swelling or a broken tooth, please make contact rather than waiting — early assessment usually means simpler treatment.
