I love this stuff!
I originally bought it for a backpacking trip as it was light, took up less room than a tube of toothpaste and it was one less liquid item in my pack when going through airport security.
But I love it so much that I use it every day now instead of toothpaste. I makes my mouth feel clean and doesn't bother my super-sensitive-to-everything gums and lips like straight up baking soda does. It has a mild, nice taste...not overly minty, which I like.
I poured a bit into a tiny plastic vial and keep it in my purse with a travel toothbrush for on-the-go touch-ups. And if I'm in a real hurry, I just put a bit into my mouth with a bit of water and swish around for a quick freshening rinse.
Pro Tip: Try not to get the dispensing hole wet as it'll clog up. If it does, just remove the cap, let it sit open for a couple hours and then blow into the bottom to clear it. WAY easier than trying to get the last bit of toothpaste out of the tube. ;)
Bonus Pro Tip: Make sure you use a super soft toothbrush...as with any gritty toothpaste or powder, you want to make sure you're not overdoing the abrasiveness.
