Hey first time poster long time lurker here. Currently 25 weeks pregnant and have had terrible trouble with my teeth (which I know is entirely my own fault for not looking after them better). In the last 6 weeks I've had two wisdom teeth removed due to infection and need a third removed due to recurring pericoronitis. However, the main problem at the minute is pain from a 1st upper molar which was deeply filled about a year ago. Dentist has suggested root canal treatment. My worry is the possible exposure to mercury vapours when the old filling is being removed. Could anyone provide advice/reassurance please on what to do? If possible I will wait until after my DD is born but the pain is awful at times.
