Q. A caller on your radio show said that using Crest desensitizing toothpaste instead of the usual brand had abolished his lifelong asthma symptoms. I went right out and bought some.
This toothpaste contains potassium nitrate, which was an ingredient in asthma relievers in the days when the pharmacist used to compound medicines. I hope this toothpaste will work for me as well.
A. Potassium nitrate, also known as saltpeter, was once prescribed for arthritis as well as asthma. Today it is employed as a preservative for cured meat and is the active ingredient in desensitizing dentifrice, including Crest Sensitivity Toothpaste.
Another listener heard the same call and has this report: “I also bought the Crest Sensitivity toothpaste and noticed immediate results. Previously, I needed my inhaler anytime I brushed my teeth. It’s been three days using the Crest, and I haven’t needed the inhaler at all.”
Do not stop your asthma medicine, but we are fascinated that switching toothpaste might help some people with their wheezing symptoms.
