A tooth infection doesn't just affect the tooth.
Research found that successfully treating apical periodontitis with root canal therapy was associated with improvements in blood sugar regulation, glucose levels, and lipid metabolism over a two-year follow-up.
Chronic tooth infections can trigger persistent low-grade inflammation, allowing inflammatory signals to circulate throughout the body. As the infection resolved, researchers observed improvements in metabolic biomarkers linked to cardiovascular health.
While root canal treatment is performed to eliminate infection and save a tooth, these findings add to growing evidence that treating oral disease may also support overall systemic health.
