I must say the concept behind this product is both horrifying and cool at the same time. The kids brush, then they use Listerine Mint Shield Smart Rinse, then they look in the mirror to see how they did. I must say the first time my kids did this, I was SHOCKED to see the evidence of poor brushing. But then I realized how awesome this was to give my kids the opportunity to see where they need to work harder to stay. When they looked in the mirror the first thing they wanted to do was pick up the tooth brush and try again to get the "bad parts". Each day after that, they looked forward to brushing together to compare how they each did. I hate to say it, but Listerine Mint Shield Smart Rinse has turned teeth brushing into a competition for my children, and I couldn't be happier. Although the concept may seem gross to highlight the germs, at the same time it is such a great experience for new independent tooth brushers.
