The results confirm yet another reason to stay regular with your cleaning appointments.
If you need more motivation to take good care of your teeth, we recently told you about lowered pancreatic cancer risk in a recent study. Now, doctors are drawing similar insight between regular visits to the dentist, and better chances of liver health.
Researchers at Virginia Commonwealth University analyzed data from nearly 48,000 U.S. Veterans with compensated cirrhosis. The Cleveland Clinic describes compensated liver cirrhosis as occurring when alcohol, drugs, virus (like hepatitis) or metabolic factors have caused scarring of the liver, but the liver is still able to function. “In the beginning,” the Clinic explains, “your body compensates for the damage, and you might not notice any symptoms. This is called compensated cirrhosis.”
Military veterans comprised the sample in the study, with 17.5% of the eligible participants actually receiving regular dental care—a striking gap that the researchers say represents a missed opportunity. The Virginia Commonwealth team of five medical doctors, public health researchers, and periodontologists (dentists who specialize in gums and dental implants) found that those compensated cirrhosis patients who received at least one dental prophylaxis or periodontal maintenance visit per year were significantly less likely to experience serious liver-related complications over the following two years.
The findings, published in the journal JHEP Reports in March 2026, showed that regular dental care was linked to lower odds of ascites (fluid buildup in the abdomen), hepatic encephalopathy (brain fog caused by liver dysfunction), and even hepatocellular carcinoma, a form of liver cancer. Patients who kept up with dental care also had lower rates of both all-cause and liver-related hospitalizations.
The connection isn’t entirely surprising to researchers who study the gut-oral-liver relationship. Poor oral health is known to drive systemic inflammation, a key engine of liver disease progression. The study authors note that “oro-dental health can affect systemic health, including progression of liver disease and cirrhosis,” yet dental care is “usually not prioritized in cirrhosis.”
“Regular dental cleanings including dental prophylaxis and periodontal maintenance may be an important tool to improve cirrhosis severity and should be considered by clinicians taking care of these patients,” the team concludes.
Importantly, the researchers ruled out the possibility that the benefit was simply a byproduct of patients who are generally more health-engaged doing better overall. When they looked separately at colonoscopy screening, another preventive health behavior, it showed no similar protective effect on liver outcomes. That finding points to something specific about oral care, rather than healthy habits in general, further confirming the results.
The study also found that the benefit plateaued at just one visit per year. That’s an accessible, low-bar intervention.
While the study population was limited to veterans—a group that skews older and male—the underlying biology may apply broadly. National data suggests cirrhosis affects an estimated 4.5 million Americans, and chronic liver disease is a leading cause of death in the U.S. For anyone living with liver disease, or at risk for it, the takeaway is straightforward: your next dental cleaning might work on more than your mouth.
