The only one of its kind?  I think so.
I think these little sugar-free mints are great.  They are sweetened with Xyletol which helps discourage tooth decay.  For someone like me who suffers from both diabetes and dry mouth, they are ideal.  I have one in my mouth at night even as I sleep to keep my mouth and throat more moist.  They are so small that I don't fear ever choking on one--can just tuck one in a corner of my mouth.  I have seen sugar-free mints that claim to neutralize acid in the mouth, but I think the benefit of actively discouraging tooth decay is even better.  If there is another mint like Smints anywhere, I don't  know of it.  The price through Amazon is good and the item was shipped at a reasonable cost also, and quickly.
