Dental caries, one of the most prevalent diseases globally, affects individuals throughout their lifetimes. Recently, researchers have increasingly focused on postbiotics for caries prevention. Postbiotics, comprising inanimate microorganisms and/or their components, confer health benefits to the host. Growing evidence suggests postbiotics’ potential anticaries effects. Specifically, numerous postbiotics have demonstrated the ability to inhibit dental caries onset and progression by modulating oral flora microecology and reducing human caries susceptibility. This review elaborates on the current research regarding postbiotics’ anticaries effects, highlights some studies’ shortcomings, and innovatively proposes that postbiotics could potentially influence tooth development and salivary characteristics through epigenetic modifications. Furthermore, it anticipates postbiotics’ future application in personalised caries treatment, given their multifaceted anticaries potential.
