I've often wondered if toothpaste really does go bad? Here's the answer.
But what happens to toothpaste when it expires?
According to Dr. John Sullivan, a Massachusetts Dental Society (MDS) member and a general dentist in Westfield, the answer is, "Nothing. The reason toothpaste has an expiration date is only because the government requires it, notes Dr. Sullivan.
All fluoride-containing toothpastes require approval from the United States Food and Drug Administration (USFDA). To this end, the USFDA requires that a two-year expiration date be put on the product container.
"The elements found in toothpaste, including fluoride, don't expire, and toothpaste isn't any less effective if it's used after the expiration date," says Dr. Sullivan.
