Re: your most important links for dental care

baking soda is in most of those recipes, too.  It is abrasive and can wear enamel and cause sensitivity for some people.  Baking soda can also act as a very mild abrasive cleaner perfect for removing stains from sinks, counter tops and even fine china.  Some people do ok with it, but I wouldn't chance it.  also, same with hydrogen peroxide, some cannot use it because it can cause sensitivity.
