Why does some toothpaste have an expiration date?


I've noticed that sometimes the toothpaste I buy has an expiration date, and sometimes it doesn't. Why is this?

cabbagehead 		The FDA requires fluoride in toothpastes to be able to bond with tooth enamel for at least two years after the manufacture date. After this time, the fluoride can bind with caking agents forming fluoride salts. The toothpaste is still safe to use, but the fluoride won't be as effective. If the toothpaste degrades shortly after two years, it must carry an expiration date.

Fluoride-free toothpastes do not require an expiration date, nor do toothpastes that have a fluoride life well beyond two years, so it's up to the manufacturer whether or not they print a date on their products. While fluoride-free toothpastes are easy to identify by the active ingredients label, long-life toothpaste depends a lot on that specific toothpaste's chemistry, which makes the application of expiration dates seem random. For example, AquaFresh's Tartar Control toothpaste doesn't have an expiration date because the manufacturer states that the fluoride is stable for over three years, but the rest of their toothpastes are dated.
