Mouthwash Linked to Loss of Sense of Taste and Tooth Discoloration

November 21, 2011 § 4 Comments

Crest Pro-Health Complete mouth rinse, which has been on the market since 2005, has hundreds of complaints against it by consumers. Consumers report a loss of sense of taste for up to a week, as well as brown teeth discoloration after use.

Kate Steeper of Foster City, CA tried the rinse two weeks ago, before bedtime. According to Steeper,  “I woke up and I noticed I couldn’t taste my breakfast.” She said her tongue felt strange as well. “It felt like when you eat pizza that’s too hot, like burning your tongue and then you can’t taste anything,” Steeper said. Her sense of taste didn’t return to normal until eight days after using the rinse. The Food & Drug Administration has received about 350 complaints about the mouth rinse. Reviewers on online retail sites such as Amazon have also posted criticisms about the product.

Crest’s FAQ page offers the following answers:

  • Does Crest Pro-Health Rinse cause taste loss?

Crest Pro-Health Rinse does not cause permanent taste alteration.

  • Oral care products containing active ingredient CPC may cause a temporary aftertaste, or temporary change in the taste of food, in a small percentage of people.
  • CPC stays in the mouth for long periods of time, which allows the rinse to provide its 12-hour benefit.
  • Aftertaste/change in the taste of food typically goes away shortly after product use is stopped.
  • Why doesn’t the Crest Pro-Health Rinse label contain a stain warning?
  • 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.

    What a load of shit! You people must think consumers are complete idiots.

  • Well, Melissa, I guess my question is do you think the article, the reports, the news coverage and even the response from Crest would be warranted if you did not experience the side effect? Why is it a “load of shit?” The reports are there. We tell consumers about it so they can protect themselves. If you choose not to believe or to decide we have something against consumers because we’re reporting on adverse effects actually reported by the company, as well as FDA and other sources. That is your choice. But remember, successful does not mean honest or ethical.

    Good luck,

    I recently got an oral piercing, and was reccomended to use nonalcoholic mouthwash several times a day to aid its healing. So I bought the pro-enamel pro-health rinse stuff by crest (white bottle). Its been 2 days of 4-times-a-day (minimum) rinsing, and I have officially lost almost all my sense of taste. Yesterday night I noticed that foods had a stronger SMELL than taste, and thought I was crazy. Now it feels like my whole tongue has that sense/taste when you burn it with hot coffee. A simple google search has now proven to me that I am not, in fact crazy.

    As I sit here eating tasteless eggs with tasteless tobasco on top, I want to warn everyone about this product.

    Do not use these products, I hope to god my sense of taste comes back, and thank you so much for writing this review.
