Make sure you change your toothbrush regularly
Make sure you change your toothbrush after you’ve been sick.
You should change your toothbrush every 3 months – this is because the bristles break down and loose their effectiveness in getting to all those tricky corners around your teeth. It is also important to change toothbrushes after you’ve had a cold, the flu, a mouth infection or a sore throat. That’s because germs can hide in toothbrush bristles and lead to reinfection.
