It's funny, the kind of conversations you find yourself having when you live with somebody. Simple things like toothpaste can become hilariously polarizing household issues if you're not careful! My boyfriend is a stalwart user of Sensodyne, while I hop from Crest to Colgate and back again. He prefers very specific flavours (mint, wintermint, super mint, mint!) while I'm cool with a baking soda flavour, or spearmint, or heck, even something crazier... like jasmine perhaps? 

And this is where Marvis Toothpaste comes into play.
