Ay, yan ang tanong mo talaga best to check with your dentist or OB muna kasi may ibang pain relievers na mas safe for breastfeeding, some of us moms were advised na paracetamol or ibuprofen lang ang okay, pero depende talaga sa brand at dosage. Ang gum swelling mo, if it's from infection or serious gum problem, kailangan talaga ng dentist check kaya go na lang, dapat iwasan mo lang ang certain procedures if possible while breastfeeding but tell your dentist you're nursing so they can guide you properly.
