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.
