UTIs do not usually cause tooth loss. Generally, tooth loss is caused by factors such as age-related tooth loss or dental caries. Uremia is a metabolic disease, mainly due to a serious decline in glomerular filtration rate, resulting in the body’s metabolic waste and toxin hoarding can not be eliminated, and ultimately lead to uremia. As the disease progresses, it may lead to a series of complications such as water-electrolyte balance disorders and acid-base imbalance, which can manifest as systemic toxicity symptoms in the digestive tract, heart, lungs, nerves, muscles, skin, blood, etc., but it generally does not lead to tooth loss. Patients with uremia should actively receive hemodialysis, peritoneal dialysis and other treatment methods to maintain life. Normally, we should regularly go to regular hospitals to monitor the body’s creatinine, urea nitrogen, trace elements, electrolytes and other index values, and find abnormalities in time for treatment to maintain the stability of the condition, while avoiding high potassium diet.
