Ive always use colgate since I was a little child, and I have had no reason to change brand at all. Although ive tried other brands I usually feel that my mouth feela fresher with colgate total. My teeth fell cleaner, and my mouth feels minty fresh. The only downside is that the prices are going up.
But I guess thats inflation for you. All in all, I dont see me shifting my brand loyalties for many many years. This is the best toothpaste.
