Orthodontista & Surgeons opinion on the role of third molars as a cause of dental crowding


Third molars that usually appear between the ages of 16 and 24 (although they may appear when older or younger). Called wisdom teeth because they appear so late—much later than the other teeth, at an age where people are wiser than a child.
They are commonly extracted when they affect other teeth—this impaction is colloquially known as “coming in sideways
Wisdom teeth are vestigial third molars. In earlier times, when tooth loss in early adulthood was common, the 3rd molar had the potential to fill in the gap left by the loss of tooth.

[Shape] It has also been postulated that the skulls of human ancestors had larger jaws with more teeth, which were possibly used to help chew food to compensate for a lack of ability to efficiently digest the cellulose that makes up a plant cell wall. As human diet changed, a smaller jaw was selected by evolution, yet the third molars, or “wisdom teeth”, still commonly develop in human mouths but most of the times end up fighting for space in the dental arch and land up impacted.
The lower dental arch crowding is an essential feature of the completed permanent dentition over the age of 17 years .
Crowding of the lower incisors is a multi-factorial phenomenon that involves a decrease in arch length, increased tooth size and abnormal shape, narrowing of the intercanine dimension, biomechanical peculiarities of tooth contacts and mandibular growth changes occurring in adolescence
