Tooth
What is Tooth?
Teeth are hard, calcified structures found in the jaws of many vertebrates, used for biting, tearing, and chewing food. They are composed primarily of enamel, dentin, and cementum, with a pulp cavity containing nerves and blood vessels. The shape and structure of teeth vary greatly depending on the animal's diet and lifestyle. While not a mineral or gemstone in the traditional sense, fossilized teeth are often collected and valued for their paleontological significance and aesthetic appeal.
