Using Denture Cleanser Safely

Case 1: An 81-year-old man soaked his dentures in an over-the-counter (OTC) denture cleanser then gargled with the remaining solution. His tongue became swollen and blue. Despite emergency efforts that included CPR and administration of isosorbide dinitrate, he died at the scene.
 
Case 2: An 84-year-old woman with a history of Alzheimer's dementia, confusion, and paranoia ate one tablet of an OTC denture cleanser. Afterward, she vomited a green substance, became delirious, and required treatment in the ED to survive.
 
Case 3: A 74-year-old nursing home resident with bronchitis ate approximately six denture cleanser tablets. She was found foaming at the mouth and having difficulty breathing. Her esophagus was irritated and her chest distended. After suffering cardiopulmonary arrest, she received CPR, was admitted to the hospital, and survived.
 
What went wrong?
Denture cleansers aren't intended for internal use, but in all three cases, they were gargled or swallowed. Some OTC denture cleansers contain ingredients associated with allergic reactions, including anaphylaxis; other ingredients can imtate mucosa and may be toxic if ingested.
 
What precautions can you take?
Carefully monitor your patients' use of denture cleansers, especially patients who may have difficulty reading or understanding label warnings and cautions. Teach patients who wear dentures to carefully read all denture cleanser labels and heed all warnings and cautions. Warn them never to chew, swallow, or gargle with denture cleansers. Remind them to always thoroughly rinse dentures and other dental appliances before placing them into the mouth.
