The oral health benefits of chewing gum.
Level 5 - mechanism / opinion, no new human data
Narrative review synthesizing existing mechanisms and clinical studies without systematic review methodology.
What was done
This narrative review summarizes scientific evidence and prospective clinical trials evaluating the oral health effects of chewing sugar-free gum. It examines physiological mechanisms driven by stimulated salivary flow—such as oral sugar clearance, plaque pH buffering, and remineralization—as well as clinical outcomes regarding caries incidence in children, plaque, extrinsic stain reduction, and active additives such as xylitol, fluoride, and calcium phosphates.
What was found
The abstract reports no quantitative values, effect sizes, or statistical metrics. It qualitatively reports that sugar-free gum stimulates saliva flow, which accelerates sugar clearance, neutralizes plaque pH following sugar challenges, enhances early lesion remineralization, and reduces caries incidence in children in prospective clinical trials.
Why it matters
It highlights how stimulated salivary flow from sugar-free gum provides a multi-mechanism adjunct to standard oral hygiene practices for caries prevention.
Limits
The abstract describes a narrative review without detailing search strategy, study selection criteria, sample sizes, or quality appraisal. No numerical data or effect sizes are provided, limiting independent assessment of the magnitude of benefit.

- context Xylitol stimulates saliva production, bringing higher levels of minerals and immunoglobulins to oral tissues.
