Both teeth and eggshells are made of stone-like minerals containing mostly calcium. Bird eggshells are made of calcium carbonate, whil dental enamel is formed from calcium phosphate. Both of these materials are classified as COMPOSITES because they are actually not pure calcium carbonate or phosphate, but also contain additional components that are softer, and allow the mineral-like crystals to bond together into a rigid structure. The precise way the composite is organized, at the microscopic level, determines whether the material is hard and resiliant (like enamel) which is resistant to cracking, or hard and brittle like eggshell that cracks much more easily. To read more about how nature uses different materials, see if you can obtain a copy of the book--- _Life's Devices_, by Steven Vogel, 1988, Princeton University press--- from a local library. Or ask one of the librarians to help you find more information on the subject if the book isn't readily available.

What is a substitute for tooth enamel?

Eggshells are a good substitute for teeth, because there both made up of similar stones like material that is made up of calcium. Eggshells are calcium carbonate, and teeth enamel is calcium phosphate. Which make both them composites, because they are both not pure calcium.

What are similarities in teeth and eggshells?

egg shells are alike teeth because they have the same calcium salts, calcium keeps the teeth healthy and strong, teeth also contain calcium carbonate, and proteins, also sea shells, bones, and coral skeletons have the samecalcium as our teeth :PCalcium is a comman component in both of these.Answercalcium is the answer. it keeps the teeth and the eggshells healthy and strong AnswerBoth teeth and eggshells contain calcium carbonate, and proteins. By the way so do bones, coral skeletons and shells.

Eggshells like teeth have a lot of calcium in them. If some substance erodes away an eggsheel, then it can have a bad effect on tooth enamel as well.
