Does Toothpaste Expire?
Yes, toothpaste does expire. Both the U.S. Food and Drug Administration (FDA) and the American Dental Association (ADA) require toothpaste to have an expiration date printed on the tube and packaging.
Toothpaste expires primarily due to the degradation of its active ingredient, fluoride. Over time, the fluoride's effectiveness in preventing cavities diminishes. While using expired toothpaste isn't inherently dangerous, its effectiveness is compromised. The expiration date ensures the fluoride remains at optimal levels for cavity protection. Colgate products, for example, typically have a two-year expiration date for this reason. [Source: Colgate]
What Happens When Toothpaste Expires?
- Reduced Effectiveness: The primary concern is the decrease in fluoride's cavity-fighting ability.
- Potential Changes in Texture and Taste: The consistency and flavor might alter, becoming less pleasant to use. [Source: Espire Dental]
While some believe that commercial toothpastes, laden with chemicals, may not "go bad," it is recommended not to use expired toothpaste, regardless of its composition. [Source: Reddit r/Frugal]
It's important to note that while using expired toothpaste is unlikely to be harmful, it's less effective and potentially less palatable. Therefore, replacing toothpaste after the expiration date is recommended for optimal oral hygiene. [Source: Try Autobrush]
Finding the Expiration Date
Check the tube and packaging of your toothpaste for the expiration date. This is usually about two years from the manufacturing date. [Source: Multiple Sources]
