Now that you've done your research, if you'd like to give it a shot, there are lots of highly-rated products to try. There's the Kopari Coconut Charcoal Toothpaste, $12, and Lush makes the Boom Dental dynamite, $10.95, a tablet you chew and then brush, thus cutting down on the plastic packaging. We've also had good luck with the Colgate Essentials Charcoal Teeth Whitening Toothpaste, $4.99.
