Dentition refers to the arrangement, type, and number of teeth in the mouth of an organism. It varies widely among species, reflecting their dietary needs and evolutionary adaptations. For example, herbivores typically have flat molars for grinding plant material, while carnivores possess sharp teeth for tearing flesh. In humans, dentition includes two sets of teeth: primary (baby) teeth and permanent (adult) teeth. Adults usually have 32 teeth, including incisors, canines, premolars, and molars. Proper dentition is essential for effective chewing, speech, and overall oral health, making regular dental care important for maintaining a healthy mouth.
