It’s normal for us to replace old shoes if they get worn out, or if your clothes become faded we buy new ones. But we never really think about replacing our old toothbrushes. This is bad since over time they become less effective at cleaning and can be contaminated with germs. We need to begin to learn when it’s time to switch to a new toothbrush and how to tell if you’re using one that’s past its prime.
So how often should we be changing our toothbrush? Well it all depends on your usage, oral health and personal preferences.
