Oral Health Matters in Cirrhosis: JHEP Reports/ March 2026

Introduction:

Cirrhosis is increasingly recognised as a multisystem disease influenced by inflammation, microbiome alterations, and extrahepatic factors. Poor oral health, particularly periodontitis, contributes to systemic inflammation and bacterial translocation through the oral–gut–liver axis. However, whether improving oral hygiene through structured dental prophylactic services can modify the natural history of cirrhosis has remained largely unexplored in large real-world cohorts.

Problem Statement and Summary:

This large Veterans cohort study demonstrates that regular dental prophylaxis (≥1 visit/year) is independently associated with significantly lower rates of cirrhosis decompensation, including ascites and hepatic encephalopathy, as well as reduced hepatocellular carcinoma incidence and hospitalisations over 2 years. Importantly, this protective effect was specific to dental care and not merely a marker of healthcare engagement, as colonoscopy screening did not show similar benefits. The findings highlight a novel, modifiable and under-recognised factor in cirrhosis management.

Clinical Implication:

Routine dental care should be integrated into standard cirrhosis management, shifting focus toward holistic care and reinforcing the importance of the oral–liver axis in disease progression.
