I don't know much about those supplements.
I don't think a few weeks is going to affect how much plaque you have on your teeth that quickly. I know that when I eat nuts or nutbutters, my teeth feel coated afterwards.
I just came from the dentist this morning. Before reading PB I had already cut out a lot of sugar from my diet, but made the changes recommended in PB this past January. I brush once a day (unless I am going out somewhere, then I'll brush again) and floss once a day. I am too lazy to do more. No plaque to speak of, just a bit of calcification next to where the saliva glands are, super healthy gums, and I am 50.
