Crest ProHealth Toothpaste Review

When I went to the dentist after many years of not having a cleaning or x-rays, and they found I needed some serious work, I knew I had to take better care of my teeth. They gave my a prescription fluoride toothpaste. In addition to this, I decided to buy a good regular toothpaste. So I chose Crest Pro Health. I like the taste and the many benefits it touts (though I wonder if any normal toothpaste also does these things?) I noticed on the ingredients it listed a different type of fluoride from the kind usually found in other toothpastes... and it contained a lot of more of it too. I don't know if this sort of fluoride is better or not, or if it matters if there is this much more, but I took the chance. 

The negative aspects of this tooth paste is that it doesn't foam very well. If I used lots of it, much more than I normally use, then perhaps it would foam normally. I also need to pre- brush my mouth after eating or else the toothpaste just goes "flat" and is like water in my mouth.
