Neither of those links show any cases of toothpaste actually harming you.
If you're trying to argue dentists are causing other people's bad teeth and gum disease by offering up toothpaste, I'd argue that isn't the case. I had this phase where I didn't brush my teeth at all until the day before a dentist appointment. I had gum disease. I can guarantee that tooth paste doesn't cause that, since I didn't use any.
So yeah, use toothpaste until some ground-breaking evidence emerges that toothpaste is bad.
