This spiky piece of rubber that resembles a sea anemone is the Rolly, a product that claims to be just as effective as giving your teeth a good brushing when you're on the go.
Here's how it works:
Besides reaching into every nook and cranny of your mouth, and gently stimulating your gums while you chew it, the Rolly contains Xylitol and Fluoride which are claimed to fight plaque and strengthen tooth enamel. And using the small disc doesn't require toothpaste, a mirror, or even water to rinse your mouth out afterwards. When you're done, you just spit it into the garbage like a piece of gum.
It looks like a scary little squid creature to me, but if it works I guess I'd give it a go. Would you?
