Green tea mouthwash takes on plaque and gum disease in new study

This study tests whether a pure green tea mouthwash can reduce dental plaque and gum inflammation better than a placebo or essential oils mouthwashes like Listerine. About 44 healthy adults will rinse with their assigned mouthwash twice daily for 3 weeks, avoiding all other oral hygiene. Researchers will measure plaque buildup and gum health at several points to see which rinse works best.
