I can't say enough for Neem and how many great uses it has. But this isn't just a tooth powder - it also has Xylitol, probiotics (in the form of S. Saliverus K12, and vitamin D). Go ahead and google streptococcus saliverus K12 - you will see that there have been some studies showing that it's a great probiotic for oral health that has been demonstrated to have a number of health benefits, including preventing plaque from sticking to teeth - a particular benefit for me. In addition, this is fluoride free, glycerine free, etc.<br /><br />I used tooth powder as a kid at times, so for me, there is little adjustment to this tooth powder. I do think that people who are really used to toothpaste might require a bit of an adjustment. This stuff foams up, but it doesn't have the same feel in the mouth as toothpaste, and it probably seems odd to sprinkle powder on a damp toothbrush and then expect your teeth to end up clean. But clean they will end up!<br /><br />This is obviously the cinnamon flavor, and to me, at least, this stuff tastes great! Better than any toothpaste I've used - I really look forward to it. I have my kids on this stuff, and they love it, too. And like most kids, if something doesn't taste good they won't go near it.<br /><br />A word of caution, though - this is a small bottle. All it takes is a few sprinkles and you can brush your teeth, but if you are expecting a lot of product, you'll be disappointed. The bottle itself notes that there's enough for around 200 brushings, and that seems about right (note though that I'm not sure that if you brush 2X/day, the probiotics will be alive and active after 100 days). Lastly, the price on Amazon is a good bit higher than on many other web sites, if you poke around. I'm a Prime member, so the free shipping really offsets the difference, but others might be better off elsewhere.<br /><br />Anyway, this is great stuff and I'm combining it now with Coral toothpaste (also fluoride and glycerine free) in an experiment. So far so good.<br /><br />POST-SCRIPT - 12/11/2014 - So a couple weeks ago I had a dentist appointment. Normally mine last quite a while - I get a lot of stuff on my teeth. This time... nothing. Hygienist had nothing to do. Dentist came in - poked around a bit - said &#34;everything's OK.&#34; Done. I was in and out in 1/2 an hour - a record.<br /><br />So I swear by this stuff now.<br /><br />POST-SCRIPT - 5/21/2015 - teeth whiter than ever. Some old stains that I'd had forever are gone. Dental visits are shorter than ever. This stuff is tremendous.

Taste better than any other tooth powder I've used. It's spicy but not too much. I love it and I will be purchasing it again. It's a tiny bottle but it lasts for a long time if you just use a little each time. It doesn't take much to do the job.

used to love this product. For some reason they added stevia to it. Disgusting taste and a major allergen. this is a great brand, but very bad decision. at least offer a stevia free version!

Brought 2 of these 1 came with the white bottle seal the other without a seal and some of the powder is around the neck of the bottle, will return.

This stiff works great. It helps my cavity feel better. Seriously! Here’s one pointer though...<br />Don’t breathe in while your putting it up to your mouth unless you like to cough a lot. You only need to make that mistake once to learn that lesson! It’s en expensive product, but it has saved me from needing to get a filling. I’m not kidding.

This is one of the better tooth powders I've tried since making the switch. While I liked it very much as did my husband it came in second.<br />It's a little bit pricey, especially when you consider the retail price of the ingredients. The second drawback is the packaging. When you squeeze the bottle to get the product on your toothbrush you invariably end up with a fair amount on the floor or in the sink.<br />On the plus side this powder does leave your mouth very happy. It's got just the right amount of cinnamon. I'll admit that at first I thought it had too much salt but after awhile I realized that this was the reason my mouth didn't feel dry after using it.<br />Finally, I didn't find that it made either more or less of a difference in the gums than any of the other powders.<br />Hope this helps.
