Ever run out of toothpaste and grabbed a small tube from your travel kit or your dentist-visit samples supply?
Next time you do, take a look at the tube. Although the Food and Drug Administration (FDA) doesn't regulate over-the-counter toothpaste expiration dates, toothpaste packaging lists them. These expiration dates help ensure your toothpaste's ingredients remain effective in its packaging.
Though expired toothpaste can work in a pinch and is usually safe, its ingredients might not produce the desired result. So, it's best to check the expiration date and buy the freshest toothpaste you can.
