When it comes to dental hygiene, I try to do my best. Brushing, flossing and using mouthwash are all part of my twice-a-day routine. But despite my constant efforts, I’m not always so saintly — particularly when it comes to limiting sweets. A sucker for all things chocolate and gummy, I have often thought how much more convenient it would be if sweets were somehow good for our teeth. Imagine my excitement when I heard about Crest’s new Be Adventurous line of toothpastes, which includes a — wait for it — chocolate toothpaste. Yes, chocolate toothpaste.Marketed as an exciting alternative to the mint- and cinnamon-flavored pastes most of us use, Crest’s Be Adventurous toothpastes are reportedly loaded with delicious flavor while still offering the usual oral health benefits such as cavity protection, breath freshening and whitening. There are only three flavors in the line, all with exciting and tasty-sounding names: Mint Chocolate Trek, Vanilla Mint Spark and Lime Spearmint Zest. Eager to try them, I scanned the shelves at Walgreens, Kroger and Target before finally tracking them down at CVS. To my surprise, they were almost sold out. All the tubes of the Lime Spearmint Zest were gone and only a lone tube each of the Mint Chocolate Trek and Vanilla Mint Spark were left. I grabbed them, paid $4.99 apiece and headed home.First impressionI began my experiment with the obvious favorite, Mint Chocolate Trek. Unscrewing the cap gave me a big whiff of chocolate frosting. So far so good. Squeezing the paste onto my brush, I initially expected to see brown. Instead, the paste resembled mint chocolate chip ice cream: mint green color with flecks of brown. Brushing with this paste turned out to be everything I had expected and more. The toothpaste was extremely flavorful, so much so that it kept its delicious taste from beginning to end. However, it did feel weird to brush with a paste that tasted like an Andes mint. The big surprise, though, came as I prepared to rinse. Spitting out the remaining paste, I’d expected a great aftertaste. Instead, I got a mouth full of grit. Yuk.I moved on to the Vanilla Mint Spark, which gave me the impression of a typical mint toothpaste mixed with vanilla frosting. (Are we seeing a trend here or did I just have frosting on the brain?) Visually, it looked unremarkable — just a basic white paste. On the brush and in your mouth, however, it was extremely refreshing and flavorful. The mint definitely overpowered the vanilla flavor, but the ultimate result was a cool, crisp aftertaste. A far cry from the grittiness of the Mint Chocolate Trek. Fab or flub?Neither, really. While I found both toothpastes tasty, I can’t say I was completely won over by either of them. Brushing with the Mint Chocolate Trek was undoubtedly a pleasant experience, and probably the best tooth brushing experience I’ve ever had. The weird grittiness it left behind, however? Not so great. Even after several rinses, I still felt the urge to brush my teeth with my regular paste. The Vanilla Mint Spark, on the other hand, was awesome from start to finish. The taste was great and it left my mouth feeling refreshed. So why am I hesitant to sing its praises? I think the pleasant taste is not that different than regular mint toothpaste’s. Given its $5 price and big promises, it didn’t quite deliver. The Vanilla Mint Spark is nice, but I found it to be more ordinary than extraordinary.So, will I be incorporating either of these toothpastes into my regular dental routine? No. Am I glad I tried them? Sure. The Crest Be Adventurous toothpastes are worth trying at least once, just for the novelty. Beyond that, it doesn’t seem worth it.
