I have gum disease (it's well under control), so for the past several years I've swished/gargle with listerine twice a day right after tooth brushing. Then someone told me this wasn't safe to use during pregnancy. I'm 29 weeks and have been using it the entire pregnancy. I will certainly ask at my next appointment, but has anyone ever heard such a thing? I know it has alcohol in it, but it's not like I'm drinking it.
