According to the basic theory of Chinese medicine, the kidney is the master of bone and marrow production. When the kidney yin is deficient and the kidney essence is insufficient, loose teeth will occur. Patients with kidney deficiency may also exhibit soreness and weakness of the waist and knees, mental fatigue, dizziness, and urine loss. Therefore, when you feel loose teeth, accompanied by symptoms such as weakness of the waist and knees, tinnitus, deafness, dizziness and dizziness, you need to go to the Chinese medicine department for examination and diagnosis in time, and you can follow the doctor’s prescription to take appropriate oral kidney tonics to regulate. Usually, teeth in a healthy state have a certain degree of mobility in the horizontal direction, which is generally lower than 0.02mm and is not easy to be noticed. The main reason for tooth loosening is the loss of tooth bone supporting tissue caused by chronic periodontitis, trauma, infection and other conditions. Therefore, when the tooth loosens to a detectable level, the patient should go to the hospital dentistry department as soon as possible and get symptomatic treatment.
