How often should I change my Oral-B toothbrush head?

Dentists recommend replacing toothbrush head every 3 months, as the bristles become frayed and worn with use which reduces the cleaning effectiveness of the toothbrush.

Many Oral-B brush heads refills feature indicator bristles that fade halfway to help remind you when to replace your toothbrush head.

Some Oral-B handle models, like the Oral-B iO Series, have a refill change indicator directly on the display of the toothbrush handle to help remind you when it’s time for a new brush head.
