Yes, an infection in the mouth can potentially cause protein in urine, though this connection is indirect, as supported by the most recent study 1 which highlights the importance of addressing systemic inflammation and immune responses that may affect kidney function. Oral infections, particularly severe periodontal disease or dental abscesses, can trigger systemic inflammation and immune responses that may affect kidney function. When bacteria or inflammatory mediators from oral infections enter the bloodstream (bacteremia), they can damage the kidneys' filtering system, leading to proteinuria (protein in urine). This relationship is most evident in conditions like post-streptococcal glomerulonephritis, which can develop after a streptococcal throat infection and cause kidney inflammation that allows proteins to leak into urine. People with diabetes or existing kidney disease are particularly vulnerable to this connection. Some key points to consider include:
- The mechanisms by which oral infections may lead to systemic diseases, including cardiovascular disease, bacterial pneumonia, diabetes mellitus, and low birth weight, as discussed in 2.
- The importance of maintaining good oral hygiene to prevent oral infections and their potential complications, as highlighted in 3 and 4.
- The need for prompt medical attention if protein in the urine is noticed along with oral infection symptoms, to address both the oral infection and the proteinuria, as suggested in the examples. Treatment typically involves addressing both issues: dental care for the oral infection and appropriate medical evaluation for the proteinuria, with medications such as amiloride potentially reducing proteinuria, as shown in 1. Maintaining good oral hygiene through regular brushing, flossing, and dental check-ups can help prevent this potential complication. It is also important to note that while the evidence from 5 discusses the management of diabetic proteinuria, it does not directly address the connection between oral infections and proteinuria, and therefore is not directly relevant to this question.
