Should I Change Toothbrush Every Month?
While it is recommended to change your toothbrush every three to four months, it is not necessary to change it every month. However, if you have been sick or have a weak immune system, it is advisable to replace your toothbrush to avoid reinfection. It is also important to rinse your toothbrush thoroughly after every use and store it in an upright position to allow it to air dry.
