Gum disease impacts are not myths. We can now measure them! We’ve known this for a long while, but we can now tell you with a great deal of accuracy how gum disease impacts your kidney health and blood sugar control.

📋 Understanding your results
Your current clinical and lab values may already include the impact of inflammation from gum disease. The estimates below show what your values might be without it — and the potential benefit of periodontal treatment.
A measure of gum inflammation calculated from pocket depths, bleeding on probing, and gum recession. Higher values indicate more severe inflammation.
Maximum: 5000 mm²
Used only for interpreting results — not for calculations. Helps tailor the “accelerated aging” message to your age group.
A measure of your average blood sugar levels over the past 2-3 months. Higher values indicate poorer glycemic control.
Maximum: 20.0%
A measure of kidney function. Higher values indicate better kidney function. Normal is >90 ml/min.
Maximum: 150 ml/min

ⓘ Kidney aging benchmark: Normal age-related decline ≈ 1 ml/min/year (Lindeman et al., 1985, Baltimore Longitudinal Study of Aging). Decline >5 ml/min/year defines “kidney accelerated aging” (Xu et al. 2024, Clin Interv Aging. PMID: 38974512). Age is used only for messaging, not calculations.
• eGFR: β = –0.017 per mm² (95% CI –0.026 to –0.008) — adjusted for age, sex, SES, hypertension (Onabanjo et al., 2025, Table 1). Without inflammation = current eGFR + (0.017 × PISA), minimum 0 ml/min.
• HbA1c: β = +0.003 per mm² (95% CI 0.001–0.005). Without inflammation = current HbA1c − (0.003 × PISA), minimum 4.0%.
• Relative effect: (absolute effect ÷ current value) × 100%.
• Metformin comparison: Absolute increase compared to 1.0–1.5% reduction (ADA 2025).
• Age decline translation: Years of age-related decline = (absolute eGFR reduction) ÷ 1 ml/min/year — a metaphor for effect size, not an addition of age.
