Uremia does not usually cause loose teeth, which may be caused by periodontitis, trauma or tumors. Patients with uremia may show symptoms such as oliguria, edema, loss of appetite, ammonia breath, anemia, and impaired consciousness. The main reason is that the metabolic wastes in the blood can’t be discharged from the body, which in turn affects the functions in the body. However, it does not usually affect the teeth. Loose teeth may be caused by periodontitis, trauma, tumor or cyst, periodontitis patients will have loss of attachment and alveolar bone resorption and thus loose teeth; strong impact on the jaw and face will also cause loose teeth. Tumors or cysts in the jawbone can cause compression of the teeth, resulting in loosening or displacement. Whether it is UTI or loose teeth, it is recommended to consult a doctor in a timely manner and take active treatment under the guidance of a physician.
