2. Eat Eggshells
Others eschew the fancy toothpastes and swear by eating eggshells for remineralized enamel. Last we checked, eggshells weren’t really considered edible.
But it turns out that they have a similar composition to teeth, including lots of calcium. Many people report fantastic results after adopting a routine that includes eating at least one eggshell a day.
You have to boil your eggshells briefly to make sure they’re safe to eat, and then dry them thoroughly in a warm oven.
Finally, grind them into a very fine powder to avoid getting cut by sharp edges. Sprinkle the powder on anything you think will help you get it down.
