Which symptom is NOT typically associated with an avulsed tooth?

An avulsed tooth is one that has been completely knocked out of its socket. When this occurs, the body responds with certain symptoms that reflect the trauma and the state of the surrounding tissues. Bleeding from the socket is common, as the trauma to the periodontal tissues and adjacent blood vessels can lead to significant bleeding. Swelling of the gums can also accompany an avulsion due to inflammation and the body's immune response to the injury. Tooth sensitivity often follows an avulsion because of damage to the nerve endings within the tooth or the periodontal ligament.

In contrast, a lack of mobility in the context of an avulsed tooth is not a typical symptom. An avulsed tooth is no longer anchored in the socket, which generally indicates that it would no longer exhibit mobility—rather, the tooth is entirely absent from its initial location. Therefore, the correct answer, indicating what is not associated with an avulsed tooth, is indeed the lack of mobility.
