Excellent Product: I've been using its for a couple months and the flavor is fantastic. Ideally, you don't want to rinse it off your teeth so that the Active HA coats them and stays on for a while (especially at night). I've been recommending it for my patients in my office, and will see if it stops some of the smaller cavities. I'm not a paid Sponsor but love the product

Very expensive, but a good product

Flavor Name: Mint, Size: 3.4 Ounce (Pack of 1)

I like it, it seems to clean great and the flavour is good. I like that it foams more than other tooth paste. I tried it to see if it helped my wife sensitivity but it didn't, so I won't spend this kind of money on it.

Excellent, high quality toothpaste

Flavor Name: Mint, Size: 3.4 Ounce (Pack of 1)

I've tried several toothpastes, this one feels better, higher quality. Only time will tell if it will give better results. Here's hoping it will.
