A throbbing toothache is a symptom of pulpitis and requires root canal treatment of the tooth.
Pulpitis is a symptom of bacterial infection of the nerve of the tooth, and the clinical manifestations are pain from hot and cold stimulation, pain aggravated at night, and pain that cannot be localized.
The pain is very severe during the onset of pulpitis, especially in the plasma stage, when the pulp becomes septic and necrotic and throbbing pain occurs, requiring root canal treatment of the tooth. The infected nerve is removed and the root canal is sterilized, the pain disappears after the inflammation is controlled, and eventually a tight root canal filling is performed to eliminate reinfection of the root.
Untreated pulpitis can lead to periapical inflammation, and an acute attack can cause infection of the maxillofacial space, facial swelling, and in severe cases, sepsis. Timely root canal treatment is needed to the dentist.
