Pregnancy transforms your entire body — including your mouth. Hormonal changes, morning sickness, cravings and new priorities lead many moms-to-be to neglect their dental health right when they need it most. The scientific reality is clear: caring for your teeth during pregnancy also cares for your baby. May, Women's Health Month, is the perfect moment to gather what every Salvadoran mom-to-be should know.
Dental changes during pregnancy
Elevated levels of estrogen and progesterone during gestation have direct, measurable effects on the oral cavity:
- Pregnancy gingivitis: more inflamed, red, sensitive gums that bleed when brushing or flossing. It affects approximately 60-75% of pregnant women, generally between the second and eighth month.
- Pregnancy epulis (gravidum granuloma): a reddish, vascularized lump that appears on the gums. It is benign and usually disappears after delivery, although sometimes it requires removal if it interferes with hygiene or chewing.
- Higher risk of cavities: due to dietary changes (sweet cravings, more frequent meals), nausea that makes brushing difficult, and in some women, decreased salivary flow.
- Dental erosion: the gastric acid from morning vomiting wears down enamel if not handled correctly.
- Xerostomia (dry mouth): decreased salivary flow in some women, especially in the first weeks.
The Salvadoran myth of "a tooth for every child"
In many Salvadoran families a saying circulates that "the baby steals calcium from the mother's teeth" — that's why, supposedly, a woman loses one tooth per pregnancy. It is false. The calcium the baby needs to form bones and teeth comes from the mother's diet, not from her teeth. If a pregnant woman loses teeth during gestation, it is from periodontal disease or cavities — both preventable and treatable problems. The myth blames the baby for something that is really an issue of access to preventive dental care.
What treatments are safe during pregnancy?
The American College of Obstetricians and Gynecologists (ACOG) and the American Dental Association (ADA) agree on official positions: dental treatments are safe during pregnancy and, in many cases, postponing them is riskier than performing them.
- Cleanings and dental prophylaxis: safe and highly recommended throughout pregnancy.
- Fillings: safe. Preferred in the second trimester for comfort.
- Root canal: safe when there is infection. An untreated abscess represents more risk to the pregnancy than the procedure itself.
- Local anesthesia with lidocaine: safe in standard doses. Lidocaine with epinephrine is avoided in specific cases per medical judgment.
- Digital dental X-rays: safe with lead apron and thyroid collar. The radiation dose from a modern dental X-ray is extremely low — less than the natural exposure of a single day.
- Antibiotics: amoxicillin, clindamycin, penicillin are safe. Tetracycline is avoided because of its effect on the baby's teeth.
- Pain relievers: acetaminophen is safe. Ibuprofen is avoided after week 30.
What is postponed: elective whitening, non-urgent orthodontic treatments, and cosmetic surgeries.
The best time: second trimester
If you have the option to plan, the second trimester (weeks 14 to 20) is the ideal time for scheduled dental treatments. During the first trimester critical organ development of the baby occurs and elective procedures are best avoided. The third trimester becomes physically uncomfortable: lying on your back can cause supine hypotension from compression of the vena cava. The second trimester offers the best balance of fetal safety and maternal comfort.
Connection between maternal oral health and baby
Scientific evidence has linked untreated severe periodontal disease during pregnancy with:
- Premature birth (before 37 weeks).
- Low birth weight.
- Preeclampsia in some studies.
The relationship is not direct causation, but periodontitis is a modifiable risk factor. Treating gingival inflammation during pregnancy reduces that risk without consequences for the baby.
Care routine during pregnancy
- Brush twice a day with fluoride toothpaste; gentle technique to avoid worsening gingivitis.
- Daily flossing: essential because inflamed gums accumulate more plaque between teeth.
- After vomiting: rinse with water or water and baking soda. Do not brush immediately, because the enamel is weakened by the gastric acid and brushing at that moment wears it down further. Wait at least 30 minutes.
- Increase calcium intake (dairy, green vegetables, sesame) and vitamin D.
- Plenty of hydration throughout the day.
- Dental check-up visit in the second trimester, even if you have no symptoms.
- Inform the dentist of your pregnancy, weeks of gestation, medications you take, and any complications your obstetrician has mentioned.
When to seek emergency care
Contact your dentist immediately if during pregnancy you experience:
- Severe tooth pain that does not respond to acetaminophen.
- Swelling of the face or neck.
- Heavy or spontaneous gum bleeding.
- Dental trauma from a fall.
- Fever associated with tooth pain (possible infection).
Dental infections during pregnancy can spread and represent a greater risk than their treatment. Do not postpone.
Caring for your smile is caring for your baby
At Clínica Endodontics in San Miguel, we care for moms-to-be following all the safety protocols recommended by ACOG and ADA, and in coordination with the treating obstetrician when needed. If you are pregnant, do not postpone your dental health — schedule an evaluation and care for both of you.
