Toothpaste
Toothpaste is one of our common sanitary things that often goes unnoticed because most people are unaware that it has a shelf life. Did you know it actually does have a shelf life and that you shouldn’t keep it for too long? Here’s how you can see that you shouldn’t use a certain toothpaste anymore. When it goes bad, to the point that it doesn’t even help, it crystallizes and becomes useless, which means you may get oral difficulties. Remember to use it up in two years to maintain your breath fresh.
