Soap does two things: it dissolves oils that water alone can’t and it changes the pH of your skin so that bacteria don’t like to live there for a while. That’s why the 20 second thing exists.

You can’t sterilize your mouth, it’ll always be a perfect place for bacteria to live. Instead, you can focus on mechanically removing the wastes deposited with the toothbrush. Your toothpaste is just a vehicle for a nice flavor/odor, a bit of abrasive to help with cleaning, and a touch of fluoride. The real work comes from your toothbrush.

Yes you can. That's why sometimes Hydrogen Peroxide is recommended, especially for those with gym disease. Bleach kills bacteria.

Some bacteria will die and then repopulate pretty quickly. You need something stronger and prescription if you really need to control growth.
