I use Crest Pro Health. I've noticed that when I switched to a diff toothpaste I got canker sores and now that I switched back to Crest Pro Health I havent had any problems.
I like Colgate over Crest but I do like the baking soda Crest one. But I usually just add baking soda to my Colgate paste anyways.
But have you guys noticed recently that a lot of the toothpastes are gel's and not pastes? Gets me rattled when I want to put toothpaste on a pimple. Maybe it's just the ones I tend to pick up.
