Can I get a dental filling during lactation?

In general, dental fillings can be performed during lactation, but the decision should be made based on a comprehensive evaluation of the tooth damage severity, treatment methods, and medication use, strictly following medical advice.

If the tooth damage is minor, such as superficial caries without pulp involvement, normal dental filling can be performed, typically without affecting breastfeeding. The local anesthetic agents used at this time, such as lidocaine, are metabolized quickly and only minimal amounts enter breast milk, causing no significant effects on the infant. Filling materials, such as composite resin and glass ionomer, are considered safe and generally do not require special concern. However, maintaining oral hygiene after treatment is important to prevent infection.

If the tooth damage is severe, such as deep caries involving the pulp or requiring root canal treatment, local anesthesia, antibiotics, or analgesics may be used during the procedure. If anesthetic agents containing epinephrine are used, they may affect the infant through breast milk. It is recommended to suspend breastfeeding for 6–8 hours until the drugs are metabolized before resuming. Post-treatment antibiotics and analgesics should be selected carefully to ensure they are safe for breastfeeding and should be used under a doctor's guidance. If infection occurs after treatment, timely intervention is necessary to prevent the spread of inflammation and potential harm to maternal and infant health.

Prior to treatment, it is advisable to inform the dentist about breastfeeding status to help assess risks and adjust the treatment plan accordingly. Choose a qualified medical facility to ensure proper sterilization protocols and reduce the risk of infection. Schedule treatment after breastfeeding to allow sufficient time for completion and minimize impact on nursing.
