A tooth is a hard, calcified structure found in the human mouth that plays a crucial role in biting, chewing, and speaking. It is composed of different layers, including enamel, dentin, and pulp. The enamel forms the outermost protective layer, while the dentin provides support and structure. Within the tooth's core lies the pulp, which contains nerves, blood vessels, and connective tissue. Teeth come in various types, including incisors, canines, premolars, and molars, each serving a specific function in the process of breaking down food. Maintaining oral hygiene and regular dental care are essential for preserving the health and integrity of teeth.
