While on psychiatric drugs (or other pharmaceuticals like birth control pills and so on), your body can lose minerals, causing problems with the teeth.
Due to a nutrient deficient diet and other stress factors, including trauma and anxiety, most of us start to experience some tooth problems and a need for remineralization as we get older.

It’s quite easy and the cool thing is that when I am traveling, I often use a make shift version with one or two ingredients such as coconut oil, baking soda and/or castille soap. I did find that castille soap used without ample coconut oil too frequently started to burn my mouth, so i would advise mixing a small amount of it with a good amount of coconut oil and other things.
I don’t usually measure the ingredients, but would advise coconut oil as the base and a small amount of everything else.
