Will puting toothpaste on a pimple really help it go away?

I've had good an bad experiences with this. If you put a dab on a pimple for an hour or two and take it off it significantly dries the pimple out and makes it heal faster. However, I once put some toothpast over a pimple and put a bandaid over it before i went to sleep and when I woke up the toothpaste had eatin holes in my skin and it was painful.
