How Often Should You Change Your Toothbrush?

September 30, 2022

For all of us toothbrush enthusiasts out there, this is a question you’ve probably asked yourself at least once. When it comes to oral health, having the right toothbrush can make a world of difference. But with so many different types and brands on the market, how do you know when it’s time to switch toothbrushes? Let’s take a look at some helpful tips for when to change your toothbrush!

The Frequency of Changing Toothbrush

First off, let’s address the obvious: if your toothbrush is worn down or damaged in any way, you should replace it immediately. Soft bristles can quickly become frayed or bent, making them less effective and potentially causing damage to your gums. In addition, if you notice that your bristles are discolored or no longer white, it may be time for an upgrade. If you use an electric toothbrush head, check for signs of wear, such as cracks or chips in the plastic casing.

Do I really need to replace my toothbrush every 3 months?

Aside from physical damage to your toothbrush, it is also important to consider how often you should be changing it. The American Dental Association recommends replacing your manual toothbrush every three months (or sooner if the bristles start becoming frayed). The reason for this is that regular use can cause bacteria build-up on your brush head over time—which leads us into our next point.

How often should I change my electric toothbrush?

It’s generally recommended that you change your electric toothbrush every 3-4 months, depending on how frequently and diligently you use it. The bristles can eventually become frayed over time, which can make them less effective at cleaning your teeth. Also, if you share your toothbrush with other people or use it for a long period of time without replacing it, it may start to harbor more bacteria than is ideal for personal hygiene. To ensure a healthy oral routine, making sure to replace your toothbrush every few months is a smart approach – and don’t forget to floss!

How often should you change your toothbrush when you are sick?

It goes without saying that good oral hygiene includes regularly changing out our toothbrushes. However, there are certain circumstances where replacing your brush more frequently becomes especially important—namely, after being ill. Whether you have the common cold or something more serious like the flu, germs, and bacteria can easily spread through saliva onto our brushes while brushing our teeth. In order to avoid getting sick again (or worse) from using a contaminated brush head, it is best practice to get a new one after recovering from any illness.


All in all, changing out your toothbrush often is essential for maintaining good oral health and avoiding re-infection from bacteria buildup over time. While regular use will necessitate replacing your manual brush every three months, taking special care after being ill will ensure that you are always brushing with clean tools and staying healthy! So what are you waiting for? Time to switch those brushes up!
