Ay nako, I feel you, toothache while taking care of a newborn is the worst! Honestly, you should really see a dentist ASAP kasi kung gaano kasakit mo, baka may infection na or kailangan na talaga ng extraction, at hindi dapat i-delay yan especially habang nagbre-breastfeed ka pa. A few of my mum friends had dental work done even while breastfeeding, and the dentist can make sure it's safe para sa baby mo, kailangan mo lang sabihin na nagbre-breastfeed ka. Don't suffer through it na, mama, your health matters din para sa baby!
