You should change your toothbrush every three to four months. This timing is recommended because the bristles wear down and become less effective at cleaning your teeth properly
. Additionally, if the bristles become frayed or splayed, they won’t reach between teeth and along the gum line effectively
. You should also replace your toothbrush sooner if you have been sick to avoid reinfection, especially since bacteria and germs can accumulate on the bristles and potentially transfer illness
. Children may need to change their toothbrushes more often, approximately every two months, due to more vigorous brushing
. Maintaining your toothbrush by rinsing it thoroughly after each use, storing it upright to air dry, and avoiding closed containers that promote bacterial growth can help keep it cleaner between replacements
. In summary:
- Replace toothbrush every 3 to 4 months
- Replace sooner if bristles are frayed or after illness
- Children may need replacement every 2 months
- Keep toothbrush clean and dry between uses
This schedule helps ensure effective cleaning, reduces bacterial buildup, and supports good oral health
