I have elevated hs-CRP and recently learned I have periodontitis. Can treating the gum disease lower my hs-CRP?

The evidence suggests yes, with some degree of effect. Several intervention studies have shown that scaling and root planing (deep cleaning of the periodontal pocket) produces measurable reductions in serum hs-CRP levels, with effect sizes ranging from 0.3 to 0.8 mg/L in studies where baseline hs-CRP was significantly elevated. The improvement follows a reduction in periodontal bacteremia and the associated systemic inflammatory signaling. The 49-year-old patient I described in the dental deep dive reduced his hs-CRP from 3.4 to 1.6 mg/L after periodontal treatment, a reduction entirely attributable to addressing the gum disease, with no other intervention changed.

Whether this hs-CRP reduction translates to reduced cardiovascular events is the open question that large intervention trials have not yet definitively answered. The PAROKRANK study (Sweden, 2023) showed that a history of periodontitis was associated with significantly higher myocardial infarction risk. The biological plausibility of the treatment benefit is strong. The RCT evidence for hard cardiovascular outcomes from periodontal treatment is still accumulating.

Cardiologist's calibrated position, Promising (2). hs-CRP reduction from periodontal treatment: documented. Hard cardiovascular event reduction: biologically plausible, RCT confirmation pending.

What to do: Treat the periodontitis and recheck hs-CRP at 3–4 months. The response is a direct measure of whether the gum disease was a significant contributor to your inflammatory burden.
