Fetched from Food and Drug Administration Consumer Updates
FDA has received at least 73 reports of adverse reactions, including at least one death, related to the use of denture cleansers. Problems have occurred with both proper and improper use of these products.
FDA is asking manufacturers of denture cleansers to include a warning in the label about persulfates, which are known to cause allergic reactions in some people. Persulfates are used in most denture cleansers as part of the cleaning and bleaching process. The agency is also recommending that manufacturers consider appropriate alternatives to persulfates.
An allergic reaction to persulfates may not occur after the first use or even until after many years of use. Symptoms of an allergic reaction may not appear for several minutes or even hours after actual use. Symptoms may include irritation, tissue damage, rash, hives, gum tenderness, breathing problems, and low blood pressure.
Other reactions may be due to misuse of denture cleansers. For example, some cleansers may list mouthwash as an ingredient, but consumers should never chew, swallow, or gargle with denture cleansers.
To reduce misuse of denture cleansers, FDA is also recommending that manufacturers improve the directions on the label. Labeling revisions are needed to make it clear that these products are meant to clean dentures in a container, not while still in the mouth. Some patients have gargled or swallowed denture cleansers, resulting in abdominal pain, vomiting, seizures, breathing problems, and low blood pressure. Dentures should be thoroughly rinsed with water before they are placed in the mouth.

I am the wife of a man who has recently had two anaphylactic episodes due to what I suspect might possibly be persulfates in dental cleansers. I have called numerous labs, asked our newly acquired allergists at Eastern Virginia Medical School, the FDA, our Dentists, local dermatologists, LabCorp, etc, and on and on as to “where” my husband could be patch tested for allergies to persulfates and no one seems to have a clue. I am writing you in hopes you might be able to give me a hint as to where in the US I might find a lab or doctor who does such testing?
My husband began having a rash on various parts of his body about 9 months ago. About two months ago and the day after a midnight anaphylactic episode, we were in Eastern Virginia Medical School’s Allergy Department beginning the process of testing for the culprit. After another anaphylactic episode followed by my husband’s discovery of a rash on his pallet, I went on line and found that persulfates in Denture Cleansers have recently made the headlines for causing mild to severe reactions in some people. One death has been traced to them. I have read numerous articles about the allergies to persulfates in the Denture Cleansers and have talked to the company of the Denture Cleanser my husband has used ( who admits the persulfates are in their product and that they are soon to put a warning on their Cleanser packaging but even he cannot tell me where my husband can be tested for an allergy to the persulfates)
The testing done at EVMS turned up that he is allergic to almonds and beef. One might tell my husband to simply stop using the Denture Cleansers, avoid beef and almonds and keep on going. However, since beef is a food that I would like to continue to serve if possible, I would like to rule out the persulfates or “rule in” them since the anaphylactic reaction may have been to the combination of both or whatever. Just avoiding the Dental Cleanser does not bring me peace or satisfaction for many reasons. It is believed also that the persulfates can be absorbed into the dentures so that even avoiding the Cleansers might not solve the problem right away. It is possible that he may need new dentures if he is allergic to persulfates and they have absorbed into the dentures he wears now. We would like to get to the bottom of all this but need to be tested for the persulfates. Do you know of a Lab or Office where my husband could be tested? Any leads would be appreciated.
Sincerely,
Karen Graves
