Does Crest Pro-Health Rinse Stain Teeth Brown?

Like all mouthwashes that effectively fight plaque and gingivitis, Crest Pro-Health Rinse can contribute to temporary, surface-level brown tooth discoloration, which is reported by a small percentage of individuals.

Tooth discoloration could actually be one indication, in some people, that the product is working: after the rinse kills germs in your mouth, the dead germs can collect on the tooth surface and create the appearance of a brown stain.

Tooth discoloration could be exaggerated by many other factors, such as existing tartar on teeth, consumption of colored beverages like coffee, tea and/or red wine, or tobacco use.

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.

Does Crest Pro-Health Rinse Stain Teeth Blue?

Crest Pro-Health Rinse Refreshing Clean Mint flavor contains a blue dye.The dye is safe, will not permanently stain your teeth or tongue, and should wash away with normal eating and drinking.

However, you might want to try Crest Pro-Health Rinse Cool Wintergreen flavor, or Crest Pro-Health Night Rinse, neither of which contain blue dye.

Some consumers may notice blue specks in their sink after spitting out Crest Pro-Health Rinse Refreshing Clean Mint Flavor:

  • The blue dye in the mouthwash can bind to germs in your mouth, making them more visible when you spit into the sink.
  • Some consumers find that running water in the sink before spitting out the rinse helps prevent the blue specks from sticking.
