What ratio for salt and baking soda?
I usually go about 2/3 soda, 1/3 salt.
It’s very easy to use too much —u really only need a very little.
Next time you buy “real” toothpaste, turn around the box and read the ingredients —what’s in there to kill bacteria and fungus?
Basically nothing.
Many also have SOME form of sugar, which you really don’t need to be applying to your teeth, since we eat so much of it anyway.
