Tooth mobility indicates potential periodontal disease or trauma. When a tooth is mobile, it means that it is not firmly anchored in its socket and can move more than normal. This can be a sign of underlying issues such as periodontal disease, which involves infection and inflammation of the gums and supporting structures of the teeth. As the supporting bone and tissue deteriorate due to periodontal disease, the tooth becomes less stable and may exhibit mobility.

Additionally, trauma to the tooth from injury or excessive forces, such as bruxism (teeth grinding), can also result in mobility. This condition serves as an important diagnostic indicator for dental professionals, prompting further investigation and potential treatment to address the underlying causes to prevent further dental complications.

Other options, while they might suggest various dental conditions, do not directly correlate with the concept of tooth mobility as clearly as the potential for periodontal disease or trauma does.
