For optimal brushing, we advise you to change the brush head every three months or sooner if the brush hairs begin to widen.
The brush head is easy to change by pulling it off the toothbrush. The new brush head can be attached very easily by pushing it on the toothbrush. New brush heads can be purchased at Brusheez.com or on Amazon.
If you have any further questions, please reach out to us by submitting a ticket or calling 1-657-275-3734 Monday through Friday 8 am PST to 5 pm PST.
