Peter U.: Should you use alkaline or acidic activated water to brush your teeth?
Unfortunately, there is no uniform opinion on this. Hygienists prefer oxidative active water, environmental philosophers prefer antioxidant activated water. The pragmatists say, first acidic, then basic. It's better to ask a professional who knows what's going on in your mouth.
I have been using the same toothpaste, which is now called “Classic”, all my life. I only had to visit dentists after accidents or because of jaw problems.
Various drinkers of alkaline active water have asked me why I don't write about brushing your teeth, since you can feel how quickly the tartar disappears. I can't say anything about this from my own experience, except that I believe that by increasing the saliva pH, favorable environmental changes could take place in the mouth that would prevent tartar from forming. However, these are not due to brushing your teeth, but rather to drinking alkaline active water. My motto is therefore: Healthy saliva, healthy teeth! —> Saliva test
I think brushing your teeth is primarily a mechanical task. To clean the spaces between my teeth, I use an ultrasonic sprayer, which for hygiene reasons I operate with Anolyt, i.e. highly oxidizing acidic active water with added salt. I use Anolyt for almost every hygiene purpose, including as a highly effective deodorant.
