Can I get a dental filling during pregnancy?

In general, dental fillings can be performed during pregnancy, but it is recommended to schedule the procedure during the second trimester (months 4–6), while following relevant precautions.

During the first trimester (first three months of pregnancy), the fetus is undergoing critical organ development, and dental procedures may increase the risk of miscarriage. At this stage, the stress and pain associated with dental treatment might trigger uterine contractions, which could negatively affect fetal stability. During the second trimester (months 4–6), fetal development is relatively stable, and morning sickness typically subsides, making this a safer period for dental fillings. The physical condition of the pregnant woman is generally better during this period, and the impact of dental procedures on both the mother and fetus is minimal. During the third trimester (last three months), the physical burden on the pregnant woman increases, and prolonged supine positioning during dental treatment may affect fetal blood circulation. Dental procedures during this period may induce uterine contractions and increase the risk of preterm labor.

It is advisable to prioritize biocompatible dental materials such as composite resin or glass ionomer cement, and to avoid mercury-containing amalgam. The use of anesthetics should be minimized; if necessary, the dosage should be strictly controlled and only fetal-safe anesthetics should be used. Exposure to X-rays during pregnancy may harm the fetus, so dental radiographs should be avoided as much as possible during this period. Inform your dentist in advance and ensure they are fully aware of your pregnancy status so an appropriate treatment plan can be developed.

After the filling, maintain good oral hygiene by brushing teeth in the morning and evening, rinsing after meals, and using dental floss to prevent oral infections. Avoid consuming excessively hard, sweet, or acidic foods to reduce stress on the teeth and promote recovery. Follow the dentist's recommendations for regular follow-up visits to ensure the effectiveness of the treatment and maintain dental health.
