It is usually 28 - 32. A complete set of teeth consists of eight incisors, four canines, eight premolars, and eight molars (molars). With four wisdom teeth (third molars) our dentition comprises a total of 32 teeth. The wisdom teeth, also known as "eights", in many cases become problematic. From an orthodontic point of view, it is therefore often advised to have them removed at an early stage because they can push the posterior teeth together as a result of their pushing effect on the jaw. Lack of space, such as a narrow jaw or exceptionally wide teeth, may result in overeating or overbites and a series of other serious complaints.
The development of our teeth is, in a sense, a breakthrough on rates. The forerunners of "permanent" teeth are the baby teeth of childhood, there are 20 in number. Although they fail, they also need to be taken care of to maintain their placeholder function for healthy adult dentition and to avoid lengthy orthodontic corrections as much as possible.
