Hi withoutjoy07!

Some websites to check out are:

http://slate.msn.com/default.aspx?id=3604
http://www.dentalgentlecare.com/toothpaste.htm
http://beauty.about.com/od/beautybyaget ... hwhite.htm

Though these sites don't directly answer your question, they do give very good background on toothpaste. Website #1 is a good overall reference. Website #2 gives an email/phone contact for further questions. Website #3 talks about teeth whitening, which is something one actually do experiments on during a limited time frame (vs. cavity prevention, which would take a longer time). Note: running experiments on teeth whitening, may be very expensive!!
