Toothpaste
Hopefully, while you are cleaning your teeth regularly, you probably get through a lot of toothpaste. In which case, this post probably isn’t that useful to you. If you do find yourself in the situation of cleaning out the back of the bathroom cabinet and coming across some toothpaste, then you should know the facts.
Do not use toothpaste that is more than two years old. The ingredients separate and crystalize, which can lead to an irritated mouth, and it becomes less effective, which leads to less clean teeth. Best throw it in the bin and pick up a new tube the next time you head out.
