Liver disease / cirrhosis

Oral health effects

• Bleeding tendency (coagulopathy)

  Cirrhotic patients often show reduced platelet counts and elevated INR, leading to spontaneous gingival bleeding and increased bleeding after dental surgery.

  Mechanism: Impaired hepatic synthesis of vitamin K-dependent clotting factors (II, VII, IX, X) plus thrombocytopenia from hypersplenism/portal hypertension.

  Clinical management: Local hemostatic measures (sutures, gelatin sponge, tranexamic acid rinse) control most bleeding events; INR alone is a poor predictor of bleeding risk, so a broader hematologic/hepatology assessment is preferred over relying on INR cutoffs alone.

• Lacy white or sore patches in the mouth (oral lichen planus)

  White, reticular or erosive lesions of the oral mucosa occur with significantly higher frequency in patients with chronic hepatitis C infection.

  Mechanism: A bidirectional epidemiological association exists between HCV infection and lichen planus, though the exact immunologic mechanism is not fully established.

  Clinical management: Screen unexplained or treatment-resistant oral lichen planus patients for HCV risk factors/serology; erosive lesions may respond less well to standard topical corticosteroid therapy in HCV-associated cases.

• Yellowing of the mouth lining (mucosal jaundice)

  Yellowish discoloration of the oral mucosa, most visible on the soft palate and ventral tongue, reflecting hyperbilirubinemia.

  Mechanism: Bilirubin deposition in mucosal tissue secondary to impaired hepatic clearance.

  Clinical management: Recognize as a clinical sign of hepatic decompensation warranting medical referral; not itself an oral lesion requiring treatment.

• Xerostomia and secondary caries/candidiasis risk

  Reduced salivary flow from liver disease and associated medications (e.g., diuretics) increases susceptibility to caries, gingival inflammation, and oral candidiasis.

  Clinical management: Salivary substitutes, fluoride supplementation, and antifungal therapy as needed; reinforce preventive/hygiene protocols.

• Gum disease (periodontitis)

  People with cirrhosis have more attachment loss, deeper pockets, and about 2.6 times the odds of periodontitis compared with controls.

  Clinical management: Do a full periodontal assessment and provide non-surgical periodontal therapy and short recall; check a recent platelet count and INR before deep scaling, and use local hemostatic measures.
