Teeth are hard, calcified structures found in the mouth of many vertebrates, used primarily for biting, cutting, chewing, and grinding food. They are essential components of the digestive system, facilitating the initial breakdown of food into smaller, more manageable pieces, thus aiding in digestion and nutrient absorption. Human teeth are arranged in a fixed order within the jaw, typically consisting of incisors, canines, premolars, and molars, each designed for specific functions. For example, incisors are used for cutting, canines for tearing, and molars and premolars for grinding. Teeth are composed of multiple tissues of varying density and hardness, including enamel, the hardest substance in the human body, which covers the outer layer of each tooth. Proper dental care, including regular brushing, flossing, and dental check-ups, is vital for maintaining tooth health and preventing decay and gum disease.
