I never thought of metal oxides, I checked some toothepastes but they didn't have any. I have noticed that just about all deoderents have aluminium oxide. It would make for a fun experement to try out differnet toothpastes, deoderents and whatever else you wanted to try. As I mentioned before, the performance did drop after awhile and when I removed the h/s the toothpaste was dried and brown. Maybe colgate will come out with a silver based toothpaste.
Well, keep up that pc hygene!

What's inside toothpaste? Do they have metal oxides there? Haha looks like my varsity lab threw away money by buying water-based silicone thermal grease when they could have used .... toothpaste! Hmmm, toothpaste....
