Infection: When there is accumulation of food debris and bacteria on the tooth, inflammation of gingiva develops due to infection. Inflammation from the gingiva spreads to the fibrous tissue between the teeth and bone and finally it affects the bone. Inflammation and destruction of bone affects the foundation on which the teeth stands causing teeth mobility.

Uneven and increased amount of force during chewing can affect the tooth.

A tumor of the bone, which causes destruction to the bony architecture, also results in tooth mobility.

Blunt injury to the tooth structure is another cause of looseness of teeth.

Pain may accompany the mobility of teeth.

The tissues around a mobile tooth are invariably red, swollen and damaged.

Splinting is usually done using a thin steel wire, which is passed through the spaces between the loose teeth, and the adjacent strong teeth in a specific pattern, so as to attain maximum stabilization of the loose tooth. This procedure might be slightly painful. New methods have been devised to completely eliminate pain.
