Between 2.3% and 38.3% of roots loosen during the procedure and need to be removed and up to 4.9% of cases require reoperation due to persistent pain, root exposure or persistent infection. The roots have also been reported to migrate in 13.2% to 85.9% of cases.
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. Mandibular third molars are more commonly impacted than their maxillary counterparts.
Inflamed alveolar bone, unprotected and exposed to the oral environment after tooth extraction, can become packed with food and debris. Dry-socket typically causes a sharp and sudden increase in pain commencing 2–5 days following the extraction of a mandibular molar, most commonly the third molar. [51]

Pericoronitis is caused by an accumulation of bacteria and debris beneath the operculum, or by mechanical trauma (e.g. biting the operculum with the opposing tooth). [3] Pericoronitis is often associated with partially erupted and impacted mandibular third molars (lower wisdom teeth), [4] often occurring at the age of wisdom tooth eruption (15-26).
Periradicular surgery should be very considered where previous endodontic treatment has failed, and possible re-root treatment is the preferred option. [4] If re-root treatment is not possible, will not correct the problem or patient factors prevent it, periradicular surgery is indicated. [5] [6] [7]
A hemisection is only performed on molars, which have 2 to 3 roots. Incisors, canines, and lower premolars only have 1 root each. Hemisections are also usually performed on the lower molars rather than the upper molars. During a hemisection, a general dentist or periodontist cuts the molar in half. The root and crown on the affected side are ...
