My preferred recipe:
12 parts eggshell dust
6 parts coconut oil
3 parts baking soda
1 part Himalaya salt
According to the site, in addition to the salt above, two ingredients are optional. I haven’t used these two, but they may help.
3 parts Castile soap
Few drops of food grade peppermint essential oil.
Preparation instructions from website:
Personally, I let the coconut oil melt on top of the dry ingredients near a fireplace so that the parts are easier to mix. Eggshell dust is very dusty when dry, after all, and it can puff out at your face when touched.Give the eggshells a rinse and boil them for a few minutes to get rid of the pathogens. Then air dry them. Grind up the shells or tablets in a coffee grinder until they turn into a fine powder. Combine the ingredients in a bowl, adding coconut oil until it reaches a smooth consistency (you can adjust the amount of the coconut oil). Add the optional ingredients if you want. Store in a jar. You can use a spoon to put the mixture on your tooth brush.
Tasty and effective toothpaste! It can be eaten as well, though too much may upset the stomach due to the baking soda. I thank God for my stumbling across the recipe, for I did not enjoy previous pastes. Yes, there is some crunchy shell dust left after brushing, but it does not bother me. Having good breath is respectful to others near me, too.
I also have chickens. I used their eggshells in the paste because if they’ve picked up good minerals from the soil and food, then that is useful.
If others have tried it, or have better dental ideas, please discuss.
Finally, note that like Martin said today, even if you have perfect physical health or diet or teeth, the Lord can still have you perish due to sin like idolatry of diet.
