When Should I Change My Toothbrush?

Do you know how often you should replace your toothbrush? We speak about the importance of brushing your teeth properly, but if your toothbrush is damaged, it is impossible to brush your teeth effectively. Since you should be brushing your teeth multiple times a day to remove lingering food and bacteria, your toothbrush needs to be replaced more frequently than other items. You should be replacing your toothbrush every 3–4 months. It is also necessary to replace your toothbrush after an illness such as strep throat. There are always bacteria that linger on your toothbrush, but after an illness, you don’t want the bad bacteria to take over and cause a reinfection.
