can a cavity cause a miscarriage?

Kenni • Living life in sin city mommy to 6! Everyday is a gift I'm truly blessed.
I just got my teeth cleaned and the hygienist told me that a cavity and gum disease can cause a miscarriage. They want me to pay for a 300$ lasher cleaning and redo all my crowns and fillings about $1200 worth of work after insurance. Can't wait to see my OB and ask.
