Teeth are hard, calcified structures that are located in the mouth and are used for biting, chewing, and grinding food. They are anchored in the jawbone by the periodontal ligament and consist of several layers:

Enamel: The outermost layer of the tooth is the enamel. It is the hardest substance in the body and protects the tooth from damage.

Dentin: The layer beneath the enamel is the dentin, which is less hard than enamel but still very strong. It forms the bulk of the tooth and provides it with its shape.

Pulp: The pulp is the innermost layer of the tooth and contains blood vessels, nerves, and connective tissue. It is responsible for nourishing the tooth and providing it with sensory information.

Teeth are important for the proper digestion of food, as they help break down food into smaller pieces that can be easily swallowed and digested. In addition to their functional role, teeth also play a significant role in appearance and communication. Healthy teeth and gums are important for overall health and well-being, and maintaining good oral hygiene practices such as brushing, flossing, and regular dental check-ups can help prevent tooth decay and gum disease.
