Always reliable, great toothpaste

I ordered the fluoride free toothpaste again, and like always, it arrived quickly and was just what I expected. Been getting my toothpaste here for a while now, never had an issue.

Good products, shipping could improve

I tried the hydroxyapatite toothpaste and a bamboo toothbrush. Both felt good, noticed a difference with the toothpaste. Shipping took 10 days to reach Texas, which was a bit slow. Also, the packaging for the toothbrush was a little flimsy. Overall, happy with the products though, they're good quality for the price.

hey, was looking at their toothpaste. anyone know if it truly makes a difference for sensitive teeth? and is it actually fluoride free like it says?

N Neil 4 months ago

Yeah, I've been using their strengthening toothpaste for a few months now, and my teeth feel way less sensitive. Like, hot coffee used to be a nightmare. Big improvement for me. And yes, it's fluoride-free.

M Mia 4 months ago

Totally fluoride-free! That's actually why I switched. My dentist recommended something with hydroxyapatite. Seems to work okay, though I didn't have huge sensitivity issues to start with.

Thinking of trying out Grin, but I'm in NYC. How long does shipping usually take to get to the US? Wondering if it's worth it or if I should just find something local.

G Gwen Romero 4 months ago

Hmm, I'm not in NYC, but I'm in California and my last order took about 2 weeks to get here. It's coming from NZ, so pretty standard for international stuff.

M Mia 4 months ago

Yeah it's international, so it's not super fast. I'd say anywhere from 10 days to 3 weeks is realistic. If you're in a rush, maybe not the best bet, but if you can wait, it's good stuff.
