How the Body’s Own ‘Stop Signals’ May Help Resolve Gum Disease Inflammation

This review article looks at gum disease (periodontitis), a chronic condition where inflammation in the tissues around teeth doesn’t resolve properly, leading to ongoing tissue damage. The researchers focus on a group of naturally occurring compounds called specialized pro-resolving mediators (SPMs), which include resolvins, lipoxins, protectins, and maresins — molecules that the body makes from omega-3 and other fatty acids.

Unlike typical anti-inflammatory approaches that broadly suppress the immune system, SPMs appear to work differently: they actively help ‘turn off’ inflammation once it’s no longer needed, while also supporting tissue repair. The review explains that SPMs work through specific cell receptors to reduce the recruitment of neutrophils (a type of white blood cell), help immune cells called macrophages clean up debris more efficiently, and shift macrophages toward a tissue-repairing state.

The paper also describes how SPMs may calm down key inflammatory signaling pathways in cells, help rebalance different types of immune responses, and support healthier bone turnover around teeth by correcting an imbalance in molecules (RANKL/OPG) that control bone breakdown and formation.
