Hi, it is a common condition during pregnancy due to extra blood flow to body. It means that you need to brush and floss your teeth more often, which i am hating at the moment as it feels awful, i usually love brushing my teeth!! It should settle once you have your bub, but it is a must that you see your dentist at least once during pregnancy for a check and especially a clean to help reduce the amount of plaque build up on your teeth as this will help with bleeding gums... I'm about to go for my check and clean....boo!! Ps it is recommended that pregnant women do not have x rays during pregnancy.. Good luck with bub!!
