Tooth

A hard, bony structure found in the jaws (or mouth) of most vertebrates, used for biting and chewing food. Teeth vary greatly in size, shape, and number depending on the animal and its diet, but they generally serve the function of breaking down food to facilitate digestion. In humans, teeth are also essential for speech production. The tooth consists of a crown, which is the visible part, and a root embedded in the jawbone. The crown is covered in enamel, the hardest substance in the body, protecting the softer dentin underneath. The pulp, containing nerves and blood vessels, lies at the center of the tooth, nourishing it and providing sensation. Regular dental care is vital to maintain healthy teeth and prevent decay and other oral health issues.
