How often should you really replace your toothbrush?

Most people hold on to a toothbrush far longer than they should. Worn bristles clean less effectively and can irritate your gums.

The three-month rule

Replace your manual brush or electric brush head every three months, or sooner if the bristles look frayed. After an illness, it is also a good idea to start fresh.

Tips for making it last

Rinse your brush thoroughly, let it air dry upright and avoid sharing. Small habits make a big difference to your oral health.
