Teeth and eggshell?



why do most experimenter use eggshell to represent the teeth on their science project experiment? Please if possible answer me ASAP...Thank you for your time...:)


That is a great question, and I don't have a great answer for you.  I am sure it has something to do with the make-up of the actual egg shell and how it can pick up staining similar to teeth.
