How many teeth does an adult human usually have?

An adult human typically has 32 teeth in total, which consists of eight incisors, four canines, eight premolars, and twelve molars (including four third molars, commonly known as wisdom teeth). This standard number reflects the complete set of permanent teeth that usually emerges by the time a person reaches adulthood, typically in their late teens to early twenties. The inclusion of wisdom teeth is what brings the total count to 32 for most adults, although some may have fewer than this if they have had teeth removed or if their wisdom teeth do not develop.
