Although formally known as third molars, the common name is wisdom teeth because they appear so late – much later than the other teeth, at an age where people are presumably "wiser" than as a child, when the other teeth erupt. [8] The term probably came as a translation of the Latin dens sapientiae.
Impacted wisdom teeth happen when there's not enough room in your mouth for your third molars to emerge and they get stuck under your gum line. Why impacted wisdom teeth are so dangerous Skip to ...
Impacted wisdom teeth can also be classified by the presence or absence of symptoms and disease. Screening for the presence of wisdom teeth often begins in late adolescence when a partially developed tooth may become impacted. Screening commonly includes a clinical examination as well as x-rays such as panoramic radiographs.
Most often, the cause of impaction is inadequate arch length and space in which to erupt. That is the total length of the alveolar arch is smaller than the tooth arch (the combined mesiodistal width of each tooth). The wisdom teeth (third molars) are frequently impacted because they are the last teeth to erupt in the oral cavity.
The tooth buds of baby teeth start to develop around 6 weeks of pregnancy. Adult teeth buds start forming around 4 months of pregnancy. The entire tooth will start to form from the crown down to the root. [8] Typically, humans have 20 primary teeth and 32 permanent teeth. [9] The dentition goes through three stages. [10]
The primary teeth typically erupt in the following order: (1) central incisor, (2) lateral incisor, (3) first molar, (4) canine, and (5) second molar. [45] As a general rule, four teeth erupt for every six months of life, mandibular teeth erupt before maxillary teeth, and teeth erupt sooner in females than males. [46]

When extracting lower wisdom teeth, coronectomy is a treatment option involving removing the crown of the lower wisdom tooth, whilst keeping the roots in place in healthy patients. This option is given to patients as an alternative to extraction when the wisdom teeth are in close association with the inferior alveolar nerve , and so used to ...
