Hey mama, dental x-rays are generally okay during pregnancy, pero since you're worried, best to follow up with your OB talaga, maybe send her a message or call the clinic directly para makasiguro at matulog ka ng mahimbing, hindi mo na kailangang mag-alala. A few of my mum friends had dental work done during pregnancy and everything was fine, pero every pregnancy is different kaya mas better mag-confirm with your doctor lang para sa peace of mind mo!
