Dental neuralgia is dental neuritis, pulpitis. The causes of pulpitis are tooth decay, which causes the tooth to rot and bacteria to enter the pulp chamber, causing inflammation of the pulp. There is also a condition where the dentin is more sensitive, where the toothbed is shrunken, the enamel is destroyed, and the roots are exposed, causing the dentin to be sensitive and when stimulated by the outside world, dental nerve pain will occur. Tooth nerve pain is an inflammation of the dental pulp. The best treatment for pulpitis is “open pulp drainage”, which is a difficult operation and requires treatment at a regular dental hospital, and open pulp drainage can directly relieve the symptoms of dental nerve pain, when the pulp is inflamed, the pulp cavity will secrete a large amount of inflammatory tissue, and the pulp tissue will become edematous. These tissues will be strongly compressed by the surrounding hard tissues, which makes the dental nerve produce severe pain. When the pulp is opened and drained, the inflammatory tissue is discharged, the pulp cavity becomes larger, and the pain is relieved when the nerve is not compressed. You should pay attention to the protection of your teeth, pay attention to cleaning your mouth, and do not eat foods that are too stimulating and cause tooth sensitivity.
