White spot lesions (WSL) are early non-cavitated carious lesions where the subsurface mineral loss has produced changes in the optical properties of the enamel. These lesions are visibly detectable as the loss of translucency results in a white appearance of the enamel surface. WSL can be arrested or reversed if the cariogenic challenge is sufficiently controlled or therapeutic agents are applied to promote enamel remineralization. Sugar-free chewing gum has been shown to promote the remineralization of enamel subsurface lesions in situ. Recently, manufacturers have been adding bioavailable calcium and fluoride in various forms to enhance anticariogenic and remineralization potential. This review describes the use of chewing gum which includes bioavailable agents for remineralization of WSL. Chewing gum is a noninvasive clinical approach for WSL remineralization, but further clinical studies are needed. Providing evidence on the effectiveness of these new noninvasive treatment approaches using technologies such as optical coherence tomography remains a priority in dental research.
