Can bad dental hygiene lead to abdominal pain?

Probably not: I would see a physician. Get a diagnosis as to what is causing the pain and then consider your treatment options.

It shouldn't: It can cause loss of teeth, however. Get yourself to both a physician and a dentist for your ailments.

No: Bad dental hygiene is linked to predominantly oral problems, such as cavities, and gum disease. It also has been implicated that people with gum disease are more likely to suffer from coronary artery disease.
