When it comes to your oral health, how often do you change your toothbrush? I heard it was recommended that you get rid of a toothbrush after 3 months of use. Is this true? Or is it a shorter period of time? I tend to switch every 3-4 months if the toothbrush is starting to go, but what about you? Is sooner better? Or should you wait longer? What's the longest you went before replacing yours?
