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.

RossBoth egg shells and tooth enamel are made up of a hard mineral substance called calcium carbonate. They both act as protective barriers around a softer interior to shield against damage and wear. However, tooth enamel is more complex and durable as it is constantly exposed to acidic substances and mechanical forces in the mouth.
Not really, no.
However enamel and eggshell are made of a similar material, that would be calcium carbonate. The difference is the other chemicals it is mixed with to make either enamel or shell. But an egg can be formed that appears extra gloss on the outside of the shell making it look like it had been enameled.
In the world of Arts and Crafts there are artists that make jeweled, beaded and enameled eggs.
Eggshells and teeth enamel are alike in terms of their color range: light yellow to white; composition: calcium phosphate; and, importance. Just like teeth enamel that is a visible tissue of the tooth that protect teeth from tooth decay, eggshells are thin covering that prevent eggs from decaying.

What is the most important mineral found in egg shells?
Calcium is the most important mineral found in egg shells. It is essential for the formation and strength of the egg shell, providing structure and protection for the developing embryo inside.
What liquid will make an egg soften?
Vinegar is commonly used to soften an eggshell. When an egg is soaked in vinegar, the calcium carbonate in the eggshell reacts with the acetic acid in the vinegar, resulting in the shell dissolving and leaving the egg soft.
Are shells organic?
Yes, shells are organic material produced by marine animals such as mollusks. Shells are primarily made of calcium carbonate and are formed by the animal as a protective outer casing.
Is calcium in shells?
Yes. Eggshells are composed of approximately 95% calcium carbonate (CaCO3). One average 5.0 gram egg shell shells out 2.0 grams of calcium.
Is dropping an egg a physical change?
Cracking an egg open is a physical change since the egg and the contents inside do not become a new substance, they remain the same. The shape or the appearance or the physical structure changes that is why it is called as a physical change not chemical because the internal composition is the same.
