Whether it’s sharp and sudden or dull and constant, tooth pain is hard to ignore. Bacteria growth in the oral mucosa can contribute to gum disease and dental decay, both of which can cause pain.. A toothache or tooth pain can also be caused by an irritation of nerves in the root of a tooth or the nerves surrounding a tooth. Dental (tooth) infection, decay, injury, or loss of a tooth are the most common causes of dental pain. Dental pain may also occur after an extraction (when a tooth is pulled out). Pain sometimes comes from other areas and goes to the jaw, thus appearing to be tooth pain. The most common areas sources that radiate into the dental plates cause toothache include, pain in the jaw joint (temporomandibular joint, or TMJ), ear pain, or pain from sinus congestion/pressure.
