I was just at the dentist who mentioned that he gets a lot of new mothers who need serious fillings or root canals, even if they had really healthy teeth pre-pregnancy and took good care of their dental health. I didn't get to ask deeply about it but physiologically, how does getting pregnant affect dental health so badly?

What signals are they receiving and why would an enemy plane or munition emit these signals in the first place?
