You can take medicine for a toothache while breastfeeding, but you have to assess whether you need to take medicine. If the toothache is not very severe, just a mild pain or there are other reasons for the toothache, it is important to go to the hospital in time and if it can be treated in time, it is okay to do the treatment without medication. If you can’t go out during your monthly period or have other reasons for not getting treatment in time, you can consider taking medicine in this case. Taking medication depends on whether the medication will affect the nursing child and whether the medication can enter the child’s body through the breast milk barrier. It is safer to take cephalosporin or amoxicillin type of medication orally, but be sure not to be allergic to these drugs. Ornidazole and metronidazole class of anti-anaerobic drugs used for common oral diseases are absolutely prohibited and should not be used.
