replacing_toothbrushProper dental care involves brushing your teeth twice a day. The use of toothbrush will help you remove the plaque from your teeth as well as the other food pieces that are stuck in your teeth. Brushing your teeth two times a day for two minutes will protect your teeth against plaque and bacteria build-up. However, if your toothbrush is worn out, you are not reaping the benefits of proper oral care at all. It’s easy to know when to replace a worn-out shoe but how about your toothbrush? Do you know when to replace your toothbrush?

When to Replace Your Toothbrush

You owe it to yourself to keep a closer look at your toothbrush to ensure you are keeping your teeth healthy. According to the ADA (American Dental Association), you should change your toothbrush every three to four months. However, if your toothbrush isn’t clean or it’s already worn out, can you still expect it to polish your teeth effectively? How often should you change your toothbrush then? You may have to replace your toothbrush sooner if:

  • If the toothbrush bristles are frayed

The first sign that you need to replace your toothbrush is when the bristles are bent or crooked. This shows that the bristles are already worn out and are no longer as effective in keeping your mouth and teeth clean. 

  • You got infections

If you are diagnosed with gum disease or got an infection, then the initial step to a full recovery is to toss your old toothbrush. While the toothbrush may have cleaned your mouth, bacteria from your infections may still reside in the bristles of your toothbrush and the risk of re-infecting yourself is higher.

  • There are visible debris and dirt on your toothbrush

Even if you have not dropped your toothbrush, dirt and small debris may still accumulate at the bottom of the bristles. This dirt is very hard to remove and replacing it with a new one is just the right option.

  • You have been keeping your toothbrush in a closed container

According to experts, keeping your toothbrush in a closed container such as travel containers for more than a day is enough to create an ideal environment for bacteria to thrive. It is recommended to dispose your toothbrush after your travel.


Generally, 3 to 4 months is perfect for replacing your toothbrush but for kids, they may require more replacement because they often brush rigorously. Whether its time or not to replace your toothbrush, it is important that you keep it clean. Rinse the toothbrush under tap water after you brush and don’t forget to store it in a vertical position so the bristles can air dry. 

Develop the habit of buying new toothbrushes for everyone in the family to ensure you are protecting everyone’s teeth.
