Omega-3 and low-dose aspirin showed promise as an add-on treatment for severe gum disease in a year-long clinical trial.
Antibiotic resistance is a growing concern, prompting researchers to investigate alternative approaches to managing periodontitis. One promising strategy involves supporting the body's natural mechanisms for resolving inflammation rather than simply suppressing it.
The randomized clinical trial, published in the Journal of Periodontology in July 2026, included 109 patients with Stage III or IV periodontitis, an advanced form of gum disease that can destroy the tissues and bone supporting the teeth. All participants received professional periodontal treatment and were assigned to receive a placebo, antibiotics, high-dose omega-3 with low-dose aspirin, or both adjunctive regimens.
After one year, more than half of the patients receiving an adjunctive treatment achieved the study's treatment target, compared with fewer than one-quarter of those receiving periodontal treatment with a placebo. The researchers reported similar observed outcomes for omega-3 combined with aspirin and for antibiotics, although the trial was too small to establish that the two approaches were equivalent.
Omega-3 fatty acids can serve as precursors for specialized molecules that help the body actively resolve inflammation. Low-dose aspirin may enhance the production of certain inflammation-resolving mediators. Researchers are investigating whether this combination can help control the persistent inflammatory response responsible for periodontal tissue destruction.
Important limitations: The study included only systemically healthy non-smokers. People with gastric ulcers or blood disorders were excluded. Aspirin can increase bleeding risk and may be unsuitable for some patients, so it should not be started for gum disease without appropriate medical and dental guidance.
Larger studies involving more diverse patient populations are needed to determine which patients may benefit most. For now, omega-3 and aspirin remain under study as adjuncts to periodontal treatment, not replacements for professional care.
