Plaque and inflamed or bleeding gums
Potential benefit studied: Changes in plaque and gingivitis with local mouthwash
Supporting researchHuman trials found that curcumin and turmeric mouthwashes improved plaque and gum-inflammation measurements when used with oral hygiene.
A four-week trial assigned 150 young adults to 0.1% curcumin mouthwash, chlorhexidine or placebo mouthrinse. A separate 100-person comparison assessed turmeric and chlorhexidine mouthwashes over 21 days using plaque and gum-inflammation measures.
These preparations acted directly in the mouth. Longevity is an oral supplement rather than a mouthwash, so this evidence does not establish gum benefits from its capsules or suitability for treating dental disease.
