When my two children started to get cavities, one thing my dentist suggested was an anti-cavity mouth wash. I chose Act because the "kids" one was a fun color and I hoped my kids would be willing to try it. They both really liked the taste, so much so that I had to remind them to only use it after brushing their teeth. Interestingly enough, they were brushing more often so they could use it. I was impressed with the lid/top of the container. With one simple squeeze, it would fill to the perfect dosage. It couldn't overfill or overflow because of the clever design. I liked knowing that my kids were getting the correct amount to use. My children's dentist checkups were improved, I think because not only were they brushing more, but that the wash was getting to their back teeth and in between teeth. Now if I could just get them to floss! I decided to try the two adult flavors as well. I really like the green one and use it daily too.
