This is quite embarrassing but I have just noticed a black decay type patch underneath a molar on one of my top teeth. I'm 22 weeks pregnant and been googling and starting to panic it's going to affect the baby. It says it can happen when pregnant due to morning sickness, change in diet etc but with dentists closed etc I don't know what to do! Has anyone experienced things happening to their teeth in pregnancy before? I'm all anxious and upset as my teeth are usually in good condition!
