What is the cause of tooth pain?

The phenomenon of sore teeth is quite common in life, especially when eating hot, cold, sour or sweet foods, which often cause such adverse stimulation reactions. The main reason for this sore symptom is tooth wear, such as caries and damage to the enamel, which will cause abnormal stimulation of the dental nerves and cause such symptoms.

What causes toothache?

1. Tooth wear causes toothache:

Wear on the neck of the teeth, improper brushing methods, especially horizontal brushing, plus the use of hard-bristled toothbrushes and coarse-grained tooth powder, are the result of decades of accumulated skills. In daily outpatient clinics, more than 80% of patients have more or less wear on the neck of the teeth. Although the causes of tooth decay are different from those of cavities, the mechanism that causes soreness is the same.

2. Damage to the enamel causes toothache:

When the enamel is destroyed and the dentin is exposed, it is stimulated by temperature (cold, hot), chemical (acid, alkali) and mechanical (brushing teeth, biting hard objects), causing abnormal soreness and pain. This sensitivity is often caused by abrasion, wedge-shaped defects, acid erosion or trauma, which causes enamel defects and dentin exposure. This situation can be completely improved by using dental gold.

3. External stimulation causes toothache:

The sore and painful feeling caused by external stimulation (temperature, mechanical, chemical stimulation) of teeth is often treated by drug application, such as sodium fluoride, silver iodide, silver fluoride nitrate, etc., which needs to be performed by a doctor. Some desensitizing toothpastes are easier to use and are suitable for people with milder symptoms. If the cause is caries, the diseased tissue needs to be removed and the tooth needs to be "filled" with materials. If the exposed area of ​​dentin is too large or the drug application method is not effective, a crown should be placed to cover the tooth to protect it.

4. Oral diseases cause toothache:

Due to long-term gingivitis or periodontal disease, the gums may recede or the teeth may become loose. After the gums recede, the neck of the teeth may become more sensitive and there may be discomfort from hot or cold stimulation. Due to periodontal disease, the teeth may become loose and the bite may become weak and sore. In addition, some people may experience temporary sensitivity after teeth cleaning or periodontal surgery. This is because the dentin is exposed after root planing surgery. However, the latter is mostly temporary and most of them will disappear on their own as long as the oral cavity is kept clean.
