Review (3/5): No different than normal Colgate Total
I'd rate this lower but it works as well as if you were to buy a regular tube of Colgate Total.
However, you'd be doing yourself a disservice if you bought it for any other purpose or for the advertised supposed additional benefit of "Gum Defense". There's a reason that if you were to compare the ingredients from this Gum Defense version and other versions of Colgate Total, you'd find that they are the exact same. Additionally, it is also the reason that if you were to visit the webpage specifically for Colgate Gum Defense, it doesn't actually say anything besides having an additional graphic that says "GUM DEFENSE" in purple. What you will note though, is that it will claim the same benefits as every other "special" type of Colgate Total - Plaque, Gingivitis, Tartar Build-up, Cavities, Bad Breath. And oddly enough, the webpage for a standard tube of Colgate Total also claims to improve gum health (in 4 weeks!).
So save yourself the extra dollar and buy the normal tube of Colgate Total if you like the Triclosan toothpastes.
