I've been through a number of different brands of toothpaste throughout my life. I've had a troubled relationship with brushing my teeth -- I do it gladly now, but when I was young I viewed it as a chore. (A number of cavities, a broken tooth and a root canal have changed my mind.) During that time, I've developed some opinions on different brands of toothpaste.
I currently use Rembrandt, because it tastes good, and to be totally honest the cost reinforces the value judgement I place on brushing my teeth -- using expensive toothpaste makes me want to brush my teeth more. (I'm not above exploiting my shallowness for personal gain.)
Throughout most of my childhood, though, I used Crest. It had a decent flavor, and it was what my parents bought.
The only other toothpaste I have significant experiences with is Thomas's, which was the kind my parents use. I have had to use it on the rare occasion that I had run out of my own.
That stuff is vile in every possible way. I recommend strongly against it. I suspect my parents of self-loathing.
Talk to you tomorrow.
