How frequently do I need to change my toothbrush?
Change Your Toothbrush Every 3 Months
Contrary to popular belief, you should not wait until your next 6 month dental checkup to change your toothbrush.
We recommend changing your toothbrush every 3 months or when you notice the bristles fraying. Many toothbrush manufacturers design the bristles to change color when it is time for a new brush or electric brush head. You may notice the blue or green color start to change to white on the tips of many Oral-B brushes.
