Recommended by my dentist.
My dentist attributed some teeth issues as being caused by my having dry mouth.  I was kind of skeptical as I don't recall having even a remotely dry mouth, but agreed to try them out.  Well, those issues have abated over the last 8 months (covering about 6 visits)...  The fact they're made locally (Philadelphia) is cool, but my only complaint is that the best flavors are the blue and purple ones and there are only 1 or 2 of them in each bag.
