Breastfeeding women with toothache can take ibuprofen to relieve the pain, but they must stop breastfeeding while taking ibuprofen because ibuprofen-like drugs are secreted into breast milk as they are metabolized and absorbed by the body, and the breast milk will contain ibuprofen, which can have adverse effects on children. Therefore, breastfeeding women should stop breastfeeding while taking ibuprofen orally and continue breastfeeding only after the ibuprofen drug is completely metabolized in the body. Most of the toothaches are caused by deep caries or pulpitis, and the pain will be completely relieved after systematic treatment. If the pain is caused by pericoronitis of the wisdom tooth, local cold compresses can be used to reduce swelling and pain, as well as pericoronial rinsing and medication, so as to relieve the pain quickly.
