A large part of people forget to replace their brush head in time. Be honest, how long ago did you last replace your head? Chances are that you don't know that exactly, but that you secretly know that this was far too long ago. While brushing, your brush head wears out, which can reduce the effectiveness of your toothbrush. It is therefore recommended to replace your head every 2-3 months. We recommend that you replace your brush head every 2 months because you reach the maximum useful life of the brush with every 3 months of replacement.
