I have used the Supersmile whitening system and wanted to try the toothpaste alone. I ordered the mandarin mint on accident (toothpaste and any citrus are notorious enemies). When it arrived, I thought "what the hell, these guys must know what they're doing," and decided to give it a shot. I was VERY pleasantly surprised. It's hard to explain, but the flavor is awesome. Oh yeah, and it's also the best toothpaste I've ever used, as well.
