When the blue area on the brush almost disappears.
Every 2-3 months, depending on how often the toothbrush is used everyday.
You should change them every 6 months when you get your teeth cleaned.
Depends on usage, but our family finds every 6 months is sufficient. You can tell it's time to replace if the bristles look frayed at the ends.
Just like your normal tooth brush every 3 months.
It depends on how often one brushes their teeth. I use my up to 6 months.
