In addition, kidney deficiency may also show symptoms such as weakness of the waist and knees, mental fatigue, dizziness, tinnitus, hair loss and poor hair quality, and urination. In short, loose teeth are mostly considered to be caused by oral diseases or trauma, if they are accompanied by other symptoms such as weakness in the waist and knees and mental fatigue, it is important to see if the kidney deficiency is caused by excessive masturbation.
