Over-eruption of the opposing tooth into the unoccupied space left by the stalled eruption of a tooth is a risk factor to operculum trauma from biting. Teeth that fail to erupt completely (commonly the lower mandibular third molars) are often the result of limited space for eruption, or a non-ideal angle of tooth eruption causing tooth impaction.
There is significant variation between the reported age of eruption of wisdom teeth between different populations. [23] For example, wisdom teeth tend to erupt earlier in people with African heritage compared to people of Asian and European heritage. [23] Generally wisdom teeth erupt most commonly between age 17 and 21. [1]

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.
Typically, all baby teeth will be present by the age of three. As for all adult teeth, they erupt between the ages 6 to 14, with the exception of the third molar, also known as the wisdom teeth which normally erupt between 17 and 25 years of age. If the tooth has yet to erupt by an appropriate age, panoramic x-rays are taken.
The Medicaid rate of wisdom teeth removal may range from about $60 to around $200 per tooth, depending on the complexity of the extractions. Additional costs can include: dental examinations
Non-eruption of non-ankylosed teeth occurs due to an eruption mechanism that has failed leading to a posterior unilateral/bilateral open bite. [28] Infra occlusion is the primary hallmark of PFE. Primary teeth are most commonly affected and normally all teeth distal to the most mesially affected tooth will show characteristics of this disease.
Periapical cysts comprise approximately 75% of the types of cysts found in the oral region. The ratio of individuals diagnosed with periapical cysts is 3:2 male to female, as well as individuals between 20 and 60 years old. Periapical cysts occur worldwide. Types of Periapical cysts: Apical: 70% Lateral: 20% Residual: 10%
