Without going into the differences in all ingredients, I believe you can tell the �old/good� from the �new/junk� by the front of the package.

I have the Gentle Mint Gel flavor (which I�m pretty sure is the �old/good� stuff). On the front in red it states "Protein-Enzyme System", and also "Gentle, Low Foaming Formula", and �Formulated to Not Irritate a Dry Mouth�. On the back the only active ingredient is Sodium Monofluorophosphate (0.14% w/v fluoride ion), and it notes �Naturally Sweetened with Xylitol�.

I found both the new and old versions at a local chain pharmacy this week. The front of the "new/junk" formula states instead in red "Essential Fluoride Tooth Protection", and also "Gentle Formula", and �Designed not to Irritate a Dry Mouth�. It also has in red �New Improved pH Balance�. The only active ingredient is Sodium Fluoride (0.15% w/v fluoride ion) and no Xylitol. My understanding is that sodium fluoride is the cheaper fluoride and not as good as the other one.

There used to be a PBF version of the toothpaste and I haven�t seen that in a few months. I was able to find the �old� version of the Gentle Mint Gel in two stores this week and bought what they had on the shelf. The �new� formula was in the Fresh Mint Original flavor. I noticed the copyright date differed from the old and new versions � new had 2013 as the date.

I was able to find the PBF mouthwash in the same stores which appears to be the old formula for that (copyright date of 2010).

From what I read, one of the �improvements� they added is a foaming agent which is noticeable right away and burns your mouth.
