Listerine Smart Rinse is a post-brush mouth rinse that reveals the particles of food and plaque left behind after brushing. Because this product is specifically aimed at teaching kids how to best brush, a five-year-old girl was recruited to try the Listerine Smart Rinse.

The Smart Rinse bottle is very user friendly. The child was able to open and measure the recommended 10 milliliters (2 teaspoons) of the conditioner. She began carefully to wipe the conditioner around her mouth. While she usually doesn’t like strong mint flavors, she was able to continuously rinse for the minute required.

Instead of running the irrigation down the drain, the drain was closed so that the irrigation could be examined for any remaining particles. When she spat out the mint green rinse, dark green pieces (plaque and food particles) were scattered all over the place. It’s crude, but it helps reinforce the importance of healthy brushing habits and shows that if done improperly, brushing is completely ineffective.

After using Listerine Smart Rinse for the first time, she was enthusiastic about brushing her teeth. She tried very hard to use her own mouthwash and showed a new level of independence for her.

One disadvantage of Smart Rinse is that you cannot eat or drink for at least 30 minutes after using it. The girl taking the test likes to drink lots of water after brushing her teeth. The first few uses were a struggle to avoid water, but over time she got used to waiting to drink her water.

A word from Verywell

If you’re having trouble getting your kids to brush their teeth and you’re wondering if they are doing a thorough job, a product like Listerine Smart Rinse can be a great way to make the task more interesting. If your child immediately gets visible feedback on how well they’re cleaning, they are more likely to be better at it. You can also benefit from using a product like this to see if you have brushed properly.
