The Amish visit dentists less. Not because teeth don't hurt — because they maintain them.
Tooth Powder
Baking soda + fine salt 3:1. Optional dried mint (flavor). Pinch on wet brush. Brush normally. Soda neutralizes acid (cause of cavities), salt is antiseptic.
Clove Oil
For toothache: drop on cotton, apply to tooth. Eugenol in clove is a local anesthetic. Dentists use it in professional preparations. Don't swallow, don't apply to gums (burn).
Oil Pulling
1 tbsp coconut or sesame oil. Swish 15-20 minutes (don't swallow). Spit out. Oil pulls bacteria from between teeth. Do morning on empty stomach.
Diet
Amish diet: low sugar, lots of hard foods (raw vegetables, nuts, dried meat). Hard food = natural cleaning + jaw exercise = strong teeth.
