Hello everyone) I have a question, did you treat your teeth during pregnancy? Today is my 28th week and I had an appointment with a dentist. We started with cleaning, there's also caries and many things to treat. It was very painful during the cleaning, gums all turned red and bled, in short, it's unreal painful, painkillers can't be taken, right? So, could this be harmful for the baby? If I'm so painfully uncomfortable?
