Black walnut did not work for me. One of my cavities was way bigger when I went to the dentist. It was much deeper and it was a big bummer because I have been using black walnut extract for months! I took a couple breaks because I wasn't sure if it was ok to take it daily, but there were days that I would easily swish it in my mouth 2-3 times a day. Very disappointed.
