How often should you change your toothbrush or electric toothbrush head?
Throw it away!
We recommend that you replace your toothbrush every 3 months, although you may consider replacing it sooner if you have been sick, or stored near other toothbrushes. Some people may also find they need to replace them sooner depending on the frequency of use and brushing techniques.
If they are frayed they won’t clean as thoroughly, so when in doubt, look at the bristles! Your toothbrush should be rinsed after using to remove bacteria and stored in an open area, as sealed containers provide the ideal place for bacteria to harbor.
