the verdict
SUPPORTED
the evidence backs this
confidence 63/100
Clinical evidence demonstrates that mouthwash use provides measurable benefits in reducing dental plaque, controlling gingival inflammation, and improving oral microbial profiles. Although some economic analyses question its cost-effectiveness relative to basic brushing, its clinical efficacy is well supported by trials.
