Preventive, diagnostic and necessary restorative or emergency dental care can generally be provided during pregnancy. Delaying active infection or pain may increase complexity. Treatment should be based on clinical need, pregnancy history, medication review, informed consent and coordination with the obstetric team when additional medical risk or sedation is involved.

Pregnancy-focused assessment
- Record gestational stage, pregnancy complications, current medicines, allergies and obstetric contacts.
- Assess caries, periodontal inflammation, erosion from vomiting or reflux, periapical disease and urgent symptoms.
- Ask about nausea, food frequency, dry mouth, oral hygiene and barriers to care.
- Identify conditions requiring medical coordination, including high-risk pregnancy or planned sedation.
- Explain treatment need, alternatives, benefits of timely care and the risk of delay.
Safe, necessary dental treatment
Clinical examination, necessary radiographs with standard radiation-safety principles, local anaesthesia and required dental treatment can be undertaken during pregnancy. Position the patient comfortably, especially later in pregnancy, and allow breaks. Drug selection should be indication-specific and checked against current pregnancy guidance; avoid assuming that every medicine is either universally safe or prohibited.
Clinical decision table
| Situation | Priority | Approach |
|---|---|---|
| Routine prevention or active caries | Maintain health and prevent progression | Provide indicated care with pregnancy-aware planning |
| Acute pain or odontogenic infection | Prompt diagnosis and source control | Do not defer necessary treatment solely because of pregnancy |
| Radiograph needed for diagnosis | Diagnostic benefit | Use justified, optimised exposure and standard protection |
| Vomiting or reflux-related erosion | Reduce acid damage | Rinse after episodes, delay brushing and coordinate medical care |
| IV sedation, nitrous oxide or general anaesthesia considered | Additional maternal-fetal assessment | Coordinate with obstetric and anaesthesia teams |
Prevention and postpartum continuity
Support twice-daily fluoride toothpaste, interdental cleaning, lower-frequency sugar exposure and periodontal care. After vomiting, advise rinsing and avoiding immediate brushing. Use the pregnancy visit to plan maternal caries control and early infant oral-health guidance. Avoid overstating associations between periodontal disease and adverse pregnancy outcomes as proof that dental treatment prevents those outcomes.
