These are preliminary renderings of an idea I've had for a while to have a toothbrush hooked up with a Listerine capsule that will squirt in your mouth while brushing in the morning. I obviously don't think this would work as a product because of the design limitations, but it's a start at something.
I always found it weird how we had to brush our teeth and do a wash of Listerine to feel like we've done the job. It's funny how most these companies made themselves part of our everyday routine. I would feel weird if I didn't put skin lotion after taking a shower, or deodorant (for God's sake put deodorant)
