Left an aweful film on my teeth.
I like it because the flavor is not so stringent that it burns the inside of my lips. The mint flavor isn't too strong and the texture is nice.
It really leaves your mouth feeling squeaky clean & your breath fresh for a long time. My teeth feel clean, and my dentist has been happy with my progress at my six month checkup. It seems to remove the bad stuff as desired.
The ingredient list is impressively short and it's fluoride free. No artificial sweeteners. Cool minty freshness in one tube.
The tube has a flip-open lid that was sealed with a removable tab.
