How often should I replace my toothbrush?

It is recommended to replace your toothbrush every three to four months or sooner if the bristles become frayed. Over time, the bristles on your toothbrush can become worn out and less effective at thoroughly cleaning your teeth and gums. By replacing your toothbrush regularly, you can ensure optimal oral hygiene and prevent the buildup of bacteria on the brush. Additionally, if you have been sick or have an infection in your mouth, it is important to replace your toothbrush to avoid reinfection. Keep in mind that using an old toothbrush can also cause harm to your gums and tooth enamel. Therefore, to maintain a healthy mouth, it is a good practice to swap out your toothbrush every few months.
