Overview

Routine preventive and necessary restorative dental care during pregnancy is safe and recommended; untreated dental infection is not. Elective cosmetic or surgical procedures, by contrast, can usually wait. This guide separates the two.

Trimester-by-trimester

  • First trimester (weeks 1–13): organogenesis. Avoid elective procedures and any elective imaging. Treat acute infection.
  • Second trimester (weeks 14–27): the safest window for necessary dentistry — cleanings, fillings, treatment of active infection, problem-focused extractions.
  • Third trimester (weeks 28–40): safe in principle, but supine positioning becomes uncomfortable and the risk of triggering early labour after prolonged appointments rises. Keep visits short, semi-reclined.

X-rays during pregnancy

Diagnostic dental radiographs with proper lead apron and thyroid collar deliver negligible foetal dose — well below natural background exposure. ADA and ACOG both endorse them when clinically necessary. Elective imaging (CBCT for implant planning, panoramic for screening) should be deferred to after delivery whenever possible.

Local anesthesia & medications

Lidocaine with epinephrine is the standard local anesthetic in pregnancy. Articaine is used in many countries but data in pregnancy are more limited. Avoid prilocaine in large doses (methaemoglobinaemia risk) and avoid mepivacaine plain in late pregnancy.

Acetaminophen is the analgesic of choice. NSAIDs (ibuprofen, naproxen) should be avoided after week 20 per recent FDA guidance. Penicillins, cephalosporins, and clindamycin are generally safe; tetracyclines and doxycycline are contraindicated.

Elective procedures — implants, veneers, whitening

Dental implants, veneers, and at-home whitening trays are elective and should be deferred until after delivery, and typically after the postpartum period when general health has stabilised. There is no evidence of safety for whitening peroxide in pregnancy, and CBCT planning for implants is best done outside pregnancy.
