Gum disease and blood sugar have a two-way relationship: high blood sugar worsens gum health, and gum inflammation makes blood sugar harder to control. The exciting part is what happens when you break the cycle.
A 2022 Cochrane review of 35 randomized trials (3,249 participants) found treating gum disease lowered HbA1c by about 0.43% at 3–4 months — comparable to adding a medication.
Diabetes and periodontitis fuel each other, so calming gum inflammation helps interrupt that loop.
Periodontal treatment also reduced C-reactive protein, a marker of whole-body inflammation.
