A typical adult human has 32 teeth, including incisors, canines, premolars, and molars. These teeth serve various functions, from cutting and tearing food to grinding and chewing. The arrangement of these teeth is essential for proper oral health and function. The first set, known as primary or baby teeth, typically falls out by adolescence, making way for permanent dentition. Regular dental care, including brushing and flossing, is crucial to maintaining these teeth and preventing issues like cavities or gum disease.
