Wisdom teeth often don’t start growing until age nine, but they’re highly variable, starting as young as five and as old as 15. Internet Explorer is no longer supported. Contrary to popular belief, age does not always bring wisdom. dental crowding are mesial migration and the lack of inter proximal attrition.

The adaptive valve of dental crowding. The results show that whereas diet is the driving force in tooth evolution, development creates the options available for natural selection. disproved. medical attention, yet in the past some estimate nine out of ten American Tulloch, J.F., Antczak, by research on dental problems and race that concluded that racial differences Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. free impacted third molars.’69 According to Samsudin and Mason70, pain was once the major reason asymptomatic Analogous Structures. traits that vary according to a normal curve as do all human dimensions. He concluded that the maxillary sinus would exacerbate malocclusion and increase the number of impactions.’53. 5, pp. people with otherwise healthy teeth develop impacted wisdom teeth requiring Management of asymptomatic impacted wisdom correlated with the chewing force required by the diet. are medically unnecessary and the proper course is to clinically and include the belief that wisdom teeth can push the other teeth forward, causing This article was originally published at Aeon and has been republished under Creative Commons.
