After you've had a cold, the flu or you've just been feeling a bit under the weather, you probably chuck out your toothbrush because it's covered in all of your sickly germs, right?
A lot of people think that if you've been brushing your teeth with a certain toothbrush whilst you're sick, you need to dispose of it straight away because they believe their yucky germs become stuck in the bristles.
Turns out, that's not actually true!
Dentists agree that you don't need to throw out your toothbrush after you've had a cold or the flu unless it's ratty with splayed bristles.
The germs on your toothbrush are your own germs and they won't make you sick again because if you've gotten better, your body would have already developed antibodies to fight the bad germs.
Dentist Raha Sepehrara told The Metro, that as long as your replacing your toothbrush every three months, you should be fine!
"There's no evidence to support that you need to replace your toothbrush every time you are ill.
"Always give your toothbrush a good rinse after toothbrushing and let it dry.
"And keep it away from the toilet!"
Also, Raha advises against sharing toothbrushes, because although the bacteria won't affect you, it may affect the other person using your toothbrush.
But she also says you shouldn't be sharing toothbrushes with other people in the first place.
So as the season's change and you get the sniffles, don't worry about throwing out your toothbrush unless you've had it for over three months!
