Trust me, if you drink enough spirulina or chorophyll mixed in water you will see a significant improvement. Spirulina even made my stool neutral. I was amazed. Also, I rinse with Crest ProHeath and it worked quite well. I don't do Listerine because the alcohol burns my mouth. Yes I used to think it was killing germs but it's actually burning your gums. I should know, after awhile I had scabs in my gums can you imagine! Look into some charcoal too that may help.
