Dental treatment during pregnancy: what you can and cannot do

You can and should have dental treatment during pregnancy. The leading professional bodies — ACOG and the ADA — recommend not postponing dental care, because untreated infection in the mouth is more dangerous for a pregnancy than the treatment itself. Elective work is more comfortable in the second trimester; acute pain is treated at any stage.

Why putting it off is the worse option

The most common mistake is to endure until the birth. The «better do nothing» logic does not work here, for two reasons.

First, decay does not stop by itself. In nine months a small cavity has every chance of reaching the pulp, and instead of a simple filling you will need root canal treatment. Second, a focus of chronic infection is a load on a body that is already working for two.

Add to that the fact that after the birth a mother usually has neither the time nor the opportunity to visit a dentist calmly. So pregnancy is not a reason to postpone — it is a reason to finally get your teeth in order.

What can be done without concern

• Examination and consultation — at any stage.
• Professional hygiene — advisable, because gums inflame more easily during pregnancy.
• Cavity treatment — modern filling materials have no systemic effect.
• Root canal treatment — where indicated, with local anaesthesia.
• Emergency care for acute pain — at any stage.

What is better postponed

• Whitening — a cosmetic procedure whose safety during pregnancy has not been studied.
• Elective implant placement — not urgent, and requires lengthy healing.
• Extensive elective proceduresthat can safely wait until after the birth.

The principle is simple: anything that treats, we do; anything that merely beautifies can wait.

X-rays: the main question

This is what people fear most, and it is where the myths are thickest. A periapical dental X-ray delivers a dose that is hard even to compare meaningfully with a dangerous one: adverse effects on a fetus begin at levels hundreds of times higher than a patient receives from a single image. Modern digital sensors have reduced the dose further still.

This does not mean X-rays are taken «just in case». The ALARA principle applies — an X-ray is prescribed only when a diagnosis cannot be made, or root canal treatment monitored, without it.

Anaesthesia: there is no need to endure it

Local anaesthetics based on lidocaine, including those with adrenaline at standard dental doses, are considered safe during pregnancy. The ADA states this directly.

Trying to «put up with it without an injection» does more harm than the injection: pain raises stress hormone levels and blood pressure. A calm patient under adequate anaesthesia is a safer scenario than one gripping the armrests.

A separate word about medication afterwards: do not take painkillers or antibiotics at your own discretion. Some familiar drugs are contraindicated in pregnancy, so the prescription should come from a doctor who knows how far along you are.

When it is best to come

In the third trimester it becomes physically uncomfortable to lie in the chair for long, and there may be pressure on the inferior vena cava. Appointments are made shorter, the chair is set semi-upright, sometimes with a small cushion under the right side.

Gums during pregnancy

Bleeding gums at this time are a familiar story. Because of hormonal changes the tissues react more strongly to the same amount of plaque, and what is known as pregnancy gingivitis develops. Sometimes a local overgrowth of the gum appears — a «pregnancy epulis»; it is benign and usually disappears on its own after the birth.

What to do about it: do not stop brushing because of the bleeding — brush more gently instead, with a soft brush, and have professional hygiene. If the inflammation is marked, a periodontist will choose treatment compatible with pregnancy. More on the page periodontics page.

How an appointment at Houston goes

Tell the receptionist how far along you are when you book — it affects how the time and length of the appointment are planned. Tell the doctor about the course of your pregnancy and about your gynaecologist's instructions — the treatment plan depends on this.

We treat decay and root canals under a microscope: this lets us work more precisely and remove less healthy tissue. More about general treatment on the page general dentistry.
