Aiyo, toothache during pregnancy memang sakit gila-gila! Best thing is to see your dentist asap, they can do scaling and basic stuff safely in second trimester, just tell them you're pregnant. If it's really unbearable, extraction is possible but your dentist will assess first whether it's necessary or if it's just inflammation that can be treated. Don't tahan the pain, babe, stress and poor sleep from the ache is worse for baby than getting it checked out properly!
