Using expired toothpaste is like opening a mystery box—sometimes it’s okay, other times it’s not. While the toothpaste might still help with the basic task of cleaning your teeth, its effectiveness might be on vacation. Fun fact: did you know that toothpaste was first used by the ancient Egyptians, who mixed ingredients like crushed eggshells and pumice? Imagine how they’d react to our modern dilemmas! And, while expired toothpaste won’t necessarily harm you, it might not give you the minty freshness you’re used to. So, if you’re not keen on a surprise dental experience, you might want to grab a fresh tube.
