With hundreds of toothpaste options available, I decided to put some to the test to find out which is the most protective. Thus, my experiment was based on the question, “Which toothpaste protects enamel the best?” Both egg shells and tooth enamel are primarily comprised of a calcium compound: calcium carbonate in egg shells and hydroxyapatite in enamel. I coated egg shells with different types of toothpaste and determined which eggs were best protected when dipped in vinegar. I tested three types with a "sensitive" label and one type of "regular" toothpaste.
