What are the Causes of Loose Teeth?

Causes of loose teeth include-

Periodontal Disease (gum disease)- It is the most common reason for a loose tooth in adults. Lack of oral hygiene, smoking, diabetes and lack of regular dental cleanings can lead to periodontal disease. Accumulation of food debris and bacteria on the tooth causes inflammation of gingiva. Over a period of time the inflammation 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 stand and thereby causing teeth mobility.
Accidental Trauma- Blunt injury to the tooth structure is another cause of looseness of teeth.

Occlusal Trauma (Bite Injury)- If a tooth is out of line then it may receive more force during a bite than it can handle. This uneven and increased amount of forces during chewing can affect the tooth making them loose. Bruxism i.e. grinding or clenching of teeth can also loosen the teeth due to excessive force.
Abscess- An abscess in the gum will also make a tooth loose.
Tumor- A tumor of the bone, which causes destruction to the bony architecture, also results in tooth mobility.
