Dental pain, also referred as toothache is characterized by painful sensation in the teeth or its supporting structures which can be caused by a dental disease or a non-dental disease. Most common causes of toothache are dental cavity (pulpitis), gum disease, a damaged filling, tooth decay, tooth fracture, abscessed tooth, apical periodontitis, and alveolar osteitis. Non-dental causes include muscle pain, maxillary sinusitis, angina pectoris, psychological disorders and tumors. Pain on drinking hot or cold beverages, pain during chewing food, sensitivity of teeth, discoloration of the affected tooth, bleeding around a tooth or gums, and swelling around a tooth are some of the major symptoms associated with dental pain.
