There's Cavibloc, which is supposed to reduce cavity-inducing bacteria. It was developed at UCLA. There's also CloSYS, which is basically a highly diluted bleach that clears your mouth of bacteria. It is ADA approved. There's also Xylitol, which is also supposed to help reduce bad bacteria. I've been using all of these for the past year, and my most recent dental cleaning had almost no tartar buildup, which is really unusual for me. I have poor flossing habits. You can look into the book "Kiss your dentist goodbye" by Dr. Ellie Phillips for more info. FYI she's not a quack, but some of her claims have been controversial among other dentists.
