Mouth Guard Or A Chew Toy

Every season of hockey or football Cooper has went through mouthpieces like a dog goes through a chew toy. We have bought the nice expensive Nike one to a couple Walmart cheapie and Howie's brands. I am amazed at how they look after about a month. I have been wondering if they make a chew-proof mouth guard. 

While getting his skates sharpened last night I struck up a conversation with the employee as I was looking at mouth guards. He suggested the one pictured below. So I purchased it and we shall see if it truly chew proof because Cooper is a good test subject! It supposedly molds to your teeth better for a tighter more snug fit, and you have to pull it off to remove it. You can drink with it in too. So once his helmet is strapped he doesn't spit it out and it's not hanging on his helmet to play with. It comes in a nice case to store it safely.
