There is no so-called secret formula for dental neuralgia, which can only be effectively treated by dental filling and restorative treatment or root canal treatment. 1. When the dental nerve loses the protection of dental hard tissue due to dental defects (e.g. dental caries, dental trauma, etc.), the nerve will be sensitive to external hot and cold stimuli and the symptoms of neuralgia will appear; dental defects must be filled and repaired (i.e. dental fillings), and special materials such as resins are used for filling and repairing the defective parts of the teeth in order to effectively stop the pain. 2. If dental caries, dental trauma or periodontal diseases are not treated in time and the nerve is infected and inflamed, symptoms of pulpitis such as hot and cold pain, spontaneous pain or biting pain will occur; root canal treatment is required to remove the infected and inflamed pulp tissues in order to effectively stop the pain. Dental nerve pain is recommended to consult a doctor in a timely manner to clearly diagnose and treat the symptoms, there is no so-called secret recipe for toothache.
