Risks of Breastfeeding After Receiving Local Anesthesia for Tooth Extraction
Anesthetics pose certain health risks to humans, particularly to young children, whose immature physiology makes them more vulnerable to the effects of anesthesia. In rare cases, anesthesia may even trigger infantile paralysis. Therefore, breastfeeding mothers should avoid nursing their infants immediately after receiving anesthesia.

Risks of Breastfeeding After Dental Anesthesia
Dental extractions typically involve local anesthesia, administered in relatively small doses. Consequently, only trace amounts of the anesthetic agent enter breast milk via the bloodstream, resulting in minimal risk to the infant. However, if you are concerned about potential strain on your baby’s kidneys, it is advisable to temporarily suspend breastfeeding for 24 hours post-anesthesia. During this period, you may express milk using a breast pump to maintain lactation and feed your baby with formula instead. Additionally, avoid spicy or stimulating foods, ensure adequate rest, and drink plenty of water to accelerate drug metabolism. Normal breastfeeding may resume after 24 hours. It is also recommended that individuals maintain good oral hygiene—brush teeth twice daily, rinse mouth after meals, and adopt other preventive habits to safeguard dental health.

Additional Information: Key Considerations During Lactation
1. Avoid Spicy, Pungent, and Heat-Inducing Foods
Postpartum women often experience internal heat; consuming spicy, pungent, or heat-inducing foods may exacerbate “heatiness,” leading to symptoms such as oral ulcers, constipation, or hemorrhoids. Foods to avoid include garlic, chili peppers, black pepper, fennel seeds, alcohol, and leeks.
2. Avoid Raw, Cold, or Hard Foods
Such foods may impair spleen and stomach function, hinder digestion, and—particularly in the case of raw or cold items—promote blood stasis, potentially causing postpartum abdominal pain or prolonged lochia. Hard foods may also contribute to tooth loosening.

The above outlines the potential risks associated with breastfeeding following dental anesthesia. We hope this information is helpful to you.
