Some evidence suggests a possible association between periodontitis and chronic kidney disease but evidence for a bidirectional link is weak. The mechanisms connecting these two diseases are not fully known, but it is suggested the chronic low-grade systemic inflammation from periodontitis and/or the oral bacteria triggers an inflammatory response and progression of the kidney disease.
Periodontal treatment and good oral hygiene are a benefit for all patients since it reduces the preventable burden of the systemic inflammation associated with periodontal disease.
