What ingredient detoxifies? When comparing both the ACTIVE (Stannous fluoride) and INACTIVE ingredients with other pastes they are the same. Gimmick?

The answer is that stannous fluoride is the active ingredient that kills plaque bacteria, including at the gumline. Many, many years ago, in the 1960's, when Crest Fluoride toothpaste came out, it had stannous fluoride (the fluoride salt of Tin, SnFl2), which both prevents cavities by strengthening tooth enamel and having an antibacterial effect on plaque bacteria. After a few years, anticavity toothpastes changed the active ingredient to sodium monofluorophosphate or sodium fluoride. They did that because stannous fluoride could cause brown stains on teeth, typically in between them where food particles were lodged when people didn't floss before brushing (which a lot of people don't). The sodium versions of fluoride salts don't cause such staining, but they provide no antibacterial effect. So now Crest Gum Detoxify -- and certain other brands -- have gone back to stannous fluoride to help prevent and sometimes even reverse gum disease since it kills plaque bacteria. You'll note that other antibacterial toothpastes such as Colgate total have sodium monofluroide phosphate to help prevent cavities, and the bacteriostatic ingredient triclosan (which is found in deodorant soap or used to be) to kill and control the multiplication of plaque bacteria after brushing. So read the ingredients in any toothpaste you buy to see what the active ingredients are -- and if it promises to help kill plaque bacteria to help with gum disease, it will either have stannous fluoride which does both things, or it will have sodium monofluorophosphate plus something extra that kills bacteria such as triclosan. Another brand on the market with stannous fluoride to kill bacteria and prevent cavities is Parodontax.
