Which dental condition causes all upper teeth to be extracted?

Periodontal disease: Periodontal disease, where you loose the bone support around your teeth, would cause you to loose your teeth.

Advanced periodontal: Advanced periodontal disease is the most common reason for multiple tooth removal.

Total neglect: Advanced and untreatable periodontal disease as well as rampant caries and un-restorable teeth are the two major dental conditions that require full mouth extractions.

Advanced Disease: There are many possible reasons but ruling out trauma, then it could be advanced periodontal disease as well as from drugs. If someone is taking illegal drugs such as meth, then the teeth could go. Neglecting oral hygiene is also another reason.

Multiple reasons: Most commonly in children, untreated cavities that have caused abscesses. Most commonly in adults, periodontal (gum/bone) disease (infection). Can also be from fractured teeth, or teeth that have to be removed to facilitate orthodontic treatment. The most common cause of tooth loss is neglect. If you're concerned, please give your dentist a call.

Cancer: Gum disease, cavities, some genetic problems and cancer in the mouth- removing teeth prior to radiation and surgery is also possible.

Depends: Severe bone loss from periodontitis or bone disease or severe trauma with fractured bone and roots.

Loss of teeth: Usually you lose teeth most commonly from progressive gum disease.

Decay: Tooth decay is a primary reason for having to have a tooth removed. Often, unfortunately, if neglect is present, this may require all teeth to need removed. There are, however, medical conditions which affect salivary flow which can make one more prone to decay. Additionally, radiation to the oral and maxillofacial region may also cause the need to have teeth removed.

Cavity/gum disease: Extensive decay and or gum disease can lead to bone loss, mobility, abscess, ... And cause loss of teeth.
