An excellent mouthwash can be made by adding 25 drops of Miracle-Mineral-Supplement to 250 ml of water. When you put this solution in your mouth, the acid of your mouth activates it. This solution will keep for over a year if you keep it out of direct light. You can use as much as you need and keep the rest for the next time.
Activated Miracle-Mineral-Supplement can damage the enamel on your teeth, thus you only want to swish it for a brief period of time. The unactivated solution will not damage your enamel so you can go for extended swishing.
I have tried it both ways and prefer the unactivated solution because I feel there is less risk involved.
I too have had glowing remarks from my dentist. He was actually aware of using ClO2 for biofilm control in his rinse water, but was surprised when I told him I was using it as a mouthwash. He had heard of the Amway product, but had never run across anyone that had used it, or anything similar.
