  2. Pericoronitis - Wikipedia

    en.wikipedia.org/wiki/Pericoronitis

    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.

  3. Wisdom tooth - Wikipedia

    en.wikipedia.org/wiki/Wisdom_tooth

    Wisdom teeth (often notated clinically as M3 for third molar) have long been identified as a source of problems and continue to be the most commonly impacted teeth in the human mouth. Impaction of the wisdom teeth results in a risk of periodontal disease and dental cavities. [29] Impacted wisdom teeth lead to pathology in 12% of cases. [30]

  4. Impacted wisdom teeth - Wikipedia

    en.wikipedia.org/wiki/Impacted_wisdom_teeth

    Wisdom teeth become impacted when there is not enough room in the jaws to allow for all of the teeth to erupt into the mouth. Because the wisdom teeth are the last to erupt, due to insufficient room in the jaws to accommodate more teeth, the wisdom teeth become stuck in the jaws, i.e., impacted. There is a genetic predisposition to tooth impaction.

  5. Dentigerous cyst - Wikipedia

    en.wikipedia.org/wiki/Dentigerous_cyst

    The treatment of choice for dentigerous cyst is enucleation along with extraction of the impacted teeth. [21] If eruption of the unerupted tooth is considered feasible, the tooth may be left in place after partial removal of the cyst wall. Orthodontic treatment may subsequently be required to assist eruption.

  6. Tooth impaction - Wikipedia

    en.wikipedia.org/wiki/Tooth_impaction

    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.

  7. Periapical cyst - Wikipedia

    en.wikipedia.org/wiki/Periapical_cyst

    Secondary [clarification needed] symptoms of periapical cysts include inflammation and infection of the pulp causing dental caries. This infection is what causes necrosis of the pulp. [4] Larger cysts may cause bone expansion or displace roots. Discoloration of the affected tooth may also occur.

  8. Tooth eruption - Wikipedia

    en.wikipedia.org/wiki/Tooth_eruption

    Primary failure of eruption (PFE) is a rare disease in which tooth eruption does not occur despite space in the arch for eruption. 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.

  9. Eruption cyst - Wikipedia

    en.wikipedia.org/wiki/Eruption_cyst

    An eruption cyst, or eruption hematoma, is a bluish swelling that occurs on the soft tissue over an erupting tooth. It is usually found in children. It is usually found in children. The fluid in the cyst is sometimes clear creating a pale-coloured cyst although often they are blue.
