Why doesn the Crest Pro-Health Rinse label contain a stain warning?
The active ingredient in Crest Pro-Health Rinse has been recognized as safe and effective by an FDA advisory panel. The label meets current FDA standards. Some other mouthwashes that effectively fight plaque and gingivitis, and have the potential to contribute to temporary brown tooth discoloration, have been on the market for years, and do not carry a stain label. Crest Pro-Health Rinse’s product label does instruct users to “use [the rinse] after your normal brushing and flossing routine.” • Brown tooth discoloration from use of mouthwashes that effectively fight plaque and gingivitis is not harmful. It is reversible – and largely preventable – through options like brushing with a power toothbrush and tartar-control/whitening toothpaste, flossing, and visiting the dentist regularly.
