Number of Teeth: A normal adult dentition is 32 teeth total. There are many variations because some people genetically are missing teeth. The incisors start to erupt around 4-5 years of age along with the first permanent molar. The premolars can start as early as 8 years. The canines around 11 years and the second molars around 13-14 years.
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).
