The fastest and most effective treatment for neuralgia is to seek medical attention for nerve-killing treatment, i.e. root canal therapy. Dental neuralgia (clinically known as pulpitis) is a common clinical disease in dentistry, mainly caused by dental caries, periodontitis or dental trauma; its symptoms include hot and cold pain, spontaneous pain, night pain or paroxysmal pain and so on. Endodontitis is recommended to seek medical attention for root canal treatment; that is, the use of nerve-killing drugs (clinically known as inactivators) under the operation of the doctor to make the nerve inactive, or the use of mechanical methods to remove the nerve directly to achieve the purpose of fast and effective pain relief. If the treatment cannot be carried out in time, anti-inflammatory drugs (e.g., amoxicillin) or painkillers (e.g., ibuprofen) can be taken as prescribed by the doctor in order to alleviate the symptoms.
