What is a potential consequence of ankylosis in a tooth?

Ankylosis in a tooth refers to the abnormal fusion of the tooth root to the surrounding alveolar bone, leading to a loss of the periodontal ligament that normally provides a cushioning effect and allows for slight movement of the tooth within its socket. One of the significant consequences of ankylosis is an increased susceptibility of the affected tooth to vertical fracture.

When a tooth is ankylosed, it becomes rigidly fixed in place, eliminating the natural mobility that teeth typically have. Under chewing forces, this rigidity can lead to undue stress on the tooth structure. Since the tooth cannot flex as it normally would, any significant pressure—such as from biting or grinding—can lead to greater odds of fracture in the tooth. Thus, the correct answer emphasizes that the risk of fracture is heightened in ankylosed teeth, showcasing a critical consequence of this condition.

In terms of the other consequences listed, increased sensitivity would not directly correlate with ankylosis and is generally more associated with conditions affecting the pulp or surrounding tissues. Decreased risk of infections is also not accurate; ankylosed teeth can still be susceptible to periodontal or periapical infections. Finally, faster healing is not characteristic of ankylosed teeth, as the fusion with the bone can complic
