Endodontic disorders are generally diseases or injuries that affect the root tip or nerve of the tooth and the structures called the pulp chamber, pulp, and root canal of the tooth. In many cases, it is caused by severe decay or injury that causes an abscess or infection in the tissue below the tooth, or even the jaw bone.
Symptoms of endodontic disease include:
Hypersensitivity to hot or cold liquids and food.
Hypersensitivity to touch.
Pain - Any kind of pain that is spontaneous or throbbing, including pain not seemed to be caused by anything. Other kinds of pain may be related to exposure to hot or cold objects, an injury, or the pressure on a tooth caused by chewing or biting down.
Tenderness or swelling of the face, gums or lymph nodes.
