Dental looseness may be caused by a lack of adhesion, heavy biting force, periodontitis, or combination of  three.

The term “primary occlusal trauma” refers to excessive biting force. Excessive biting power has been exerted on the tooth, beyond its tolerance.

This may be caused by grinding or clenching your teeth while you sleep. It may also be caused by teeth that are misaligned, forcing them to bear more biting force than they should.

A second occlusal trauma is caused by the progression of gum disease, which leads in the loss of bone surrounding a tooth.

These injuries occur when the teeth are subjected to typical stresses, however the ligaments are not strong enough to bear such pressures due to the loss of bone. The most prevalent cause for tooth looseness is periodontal disease.
