What are the Most Common Causes for Tooth Loss?

Gum disease
Gum disease, also known as periodontal disease, is the number one cause of tooth loss among adults accounting for 70 percent of missing teeth.

It begins with bacteria and inflammation in the gums. As it progresses, it destroys the gum tissues and can destroy the jawbone underneath the gums, resulting in no support for the teeth.


Cavities are holes in teeth caused by a bacterial infection that turns into tooth decay. If untreated, a cavity can destroy the pulp in the center of the tooth, which will likely result in a root canal or even removal of the tooth.

Prevent cavities by practicing good oral health habits, choosing healthy foods and drinks, and making regular trips to the dentist for early detection. Early treatment can save your tooth.

Physical injury or trauma

Accidents happen, especially during sports, which is why mouth guards are important. Falls, car accidents and more can also cause tooth loss. However, you can be vigilant to avoid some common causes of tooth loss or damage through accidents. Don’t use your teeth to remove caps, tops or lids, to loosen knots, tear off tags or cut thread. Nor should you use your teeth to chew ice, open nutshells, or chew on popcorn kernels if you want to make sure your teeth stay intact.

Other diseases and risk factors 

In addition to periodontal disease, these diseases and risk factors can lead to tooth loss:

  • Diabetes
  • Hypertension
  • Arthritis
  • Smoking
  • Poor nutrition
