@mike My wife recently discovered this and bought a metric truckload of Pur gum. It's definitely not as good as other gum (namely in how long the gum's flavour and chewiness seem to last) but it's… fine I guess. If it has dental benefits then I'm all for it.
@levisan I’m glad to hear someone else has found this as well. I’ll give the Pur gum a try and maybe check out some other brands afterward to see if any others are better.
