The ânormalâ adult human has 32 teeth. An adult should have 32 teeth with 8 incisors, 4 canines, 8 premolars, and 12 molars which include the four wisdom teeth. Humans develope 2 sets of teeth in their lives. the first set known as baby teeth began to come though at about age 6 months. They eventually have about 20 teeth as children before they began to lose them. The second, permanent set of teeth consists of 32 teeth. Twenty-eight of them appear between the ages of about 6 and 12 years. Secondary teeth do not push deciduous teeth out of their sockets; instead, a group of cells (odontoclasts) forms in front of tip of second tooth and dissolves the base of first tooth.
In humans, there are usually 20 primary (baby) teeth and 28 to 32 permanent teeth, the last four being third molars or  wisdom teeth , each of which may or may not grow in. Among primary teeth, 10 usually are found in the maxilla (upper jaw) and the other 10 in the mandible (lower jaw).
