Teeth may erode for several reasons including diet, old age, or behavioral habits like grinding. Recent research suggests eggshell powder, when mixed with a glycerin solution, can aid in the remineralization of tooth enamel. This is not to say that you can generate new enamel; enamel, once lost, is lost forever. But tooth decay can be slowed, and the loss of enamel halted, with the help of a qualified dentist and eggshells. In fact, the same study determined eggshell powder contains lower levels of toxic materials than often found in other natural sources of calcium.
