Thanks, Brian. A critical point to be sure and one I was conveniently forgetting. Here's another TP from Walgreen's called The Natural Dentist Healthy Teeth and Gums Anti-Cavity Toothpaste:

Active Ingredients

Sodium Fluoride (0.24%) (0.15% w/v Fluoride Ion)Anticavity

Inactive Ingredients

Vegetable Glycerin , Silica , Water (Purified) , Sorbitol , Xylitol , Cocamidopropyl Betaine , Aloe Vera (Aloe Barbadensis) Gel , Cellulose Gum , Titanium Dioxide , Natural Flavors , Echinacea Angustifolia (Coneflower) , Goldenseal , Calendula (Calendula Officinalis) Flower , Xanthan Gum , Citric Acid , Grapefruit Seed Extract

I note that my (old formula I think) last remaining Biotene tube lists as its only active ingredient Sodium Monofluorophosphate (0.14% w/v fluoride ion).
My girlfriend's Crest has Sodium fluoride 0.243% (0.15% w/v fluoride ion)

Here's the full link to the Dentist's Natural listing:
