So far I like it just fine!
(Updated after using the product for three weeks.)<br /><br />First off, I should mention that just about all flavors of toothpaste (e.g., mint or cinnamon) have always made my mouth "burn".  There are very few brands / flavors that I find at all comfortable to use.<br /><br />I had been using this company's toothpaste for years and really liked it till they added the nano silver.  (They simultaneously made the wintergreen stronger, leaving lemon as the only flavor that didn't hurt my mouth.)  After reading up on nano silver, I decided that since it's a fairly new additive and is now being added to quite a variety of products, I'd rather wait and see whether "they" find that it causes problems down the line.  So I switched to the powder.<br /><br />The jar is surprisingly small (compared to how it looks on my laptop), only 2-1/4 " in diameter -- but that means it fits very nicely in my medicine cabinet.  Besides, it's sold by net weight, not by the size of the jar!  At the three-week mark, I've used nearly half the jar, so I estimate it'll last 6 to 8 weeks.<br /><br />I like spearmint flavor in moderation, and several reviews said this product has a mild flavor, so that's what I ordered.  I wasn't sure I'd like it unsweetened, but it's nice -- like chewing on a mint leaf (rather than mint chewing gum).  It does burn just a little, but far less than the vast majority of toothpastes.  I may try the citrus flavor next, or could try mixing the two.<br /><br />One review said that dipping a wet toothbrush into the powder was fine at first, but eventually made the powder get all clumpy.  Also, I found that dipping my wet brush into the jar picks up more powder than necessary, so I give my toothbrush a shake after wetting it, before dipping it, and I put a tiny bit of water in my mouth.  With the right water-to-powder ratio, it's  pretty much like brushing with paste.<br /><br />Another review mentioned needing to brush again with just water after rinsing, in order to get all the powder off their teeth.  I suspect that they were using it like scouring powder, rather than using enough water to make a soft paste.  Just a regular rinse works fine for me.<br /><br />I've been using the powder for three weeks now, and so far I like it just fine -- though I still wish they hadn't added the nano silver to the paste, which I find a bit easier to use.  On the other hand, the jar is recyclable and the tube isn't.  And I should easily be able to get every last bit of powder out of the jar.
