If you’re looking for a rough estimate of how often you might want to change your Electric Toothbrush head, you should do it at least once every 3-4 months.

There are quite a few reasons behind it and we are going to take a look at these in today’s article. Dental experts, however, do agree that you should do it at least once 3-4 months to ensure that you can get the most out of your brushing experience.

How often should you change the head on an Electric Toothbrush?

If you’re wondering about how often you should change the head on an electric toothbrush, I would say that the right time to do that would be at least once somewhere between every 3-4 months.

There are quite a few reasons to do this, the main ones are as follows:

  • Bristles might get frayed: One of the main reasons is that the Toothbrush head bristles might happen to get frayed by this time, and continuing to use it is not a great idea after that point of time. However, this is not the most important thing, and you need to change your toothbrush head even if the bristles don’t get frayed.
  • Development of Fungi and Bacteria: Of course, Fungi and Bacteria might also grow on your toothbrush bristles by this point, and that is the main reason why you want to change it this often- to actually not get sick from using a toothbrush head that isn’t safe to use anymore.
  • Changing it if you’re feeling unwell: Another great time to change it is when you recover from an illness. This is mostly because of the fact that you might have actually ended up putting some bacteria on the toothbrush which might cause your problem to return. To prevent that from happening, it is recommended that you change your toothbrush head once you recover from something.

Quoting Oral-B on when you should change your Toothbrush head,

Many dental professionals recommend changing your toothbrush about every three months, and the American Dental Association (ADA) recommends that you replace your toothbrush approximately every three to four months, or sooner if the bristles are frayed.

That’s because, no matter what type of toothbrush you use, its bristles can become frayed and worn and may lose their effectiveness. And clinical research shows that a new toothbrush can remove more plaque than one that’s worn out, ensuring that your brush is working its hardest to help keep your teeth clean and healthy.

Again, quoting TeethMates,

Every dentist agrees:  You need to replace the toothbrush head every three or four months. That is a must, irrespective of the condition of the toothbrush head.  Fungi and bacteria can develop on the bristles, and they lose their effectiveness.

While three to four months is the maximum you can push it to, you should also keep an eye on the brush head’s bristles…

Do Electric Toothbrushes make your Teeth Whiter?

A lot of people wonder if Electric Toothbrushes actually make their teeth whiter. Even if you change your toothbrush head frequently enough and keep in mind all the dos and don’ts of brushing, what you need to know is that an Electric Toothbrush can never make your Teeth Whiter once they have been stained.

The main thing you might want to keep here is that Electric Toothbrushes are actually more efficient than regular ones. As such, they can actually help you keep your teeth much cleaner than before, and combined with efficient tongue cleaning, you can actually have a much better oral hygiene.

However, as I just remarked, you can never really expect Electric Toothbrushes to make your teeth whiter. We have prepared an entire article about this for you right here at Tooth Advocates- click here to check it out!


In conclusion, it would be safe to say that there are quite a few things you need to keep in mind when it comes to the right time to change your toothbrush head.

The typical right time would be somewhere between 3-4 months. But this actually depends on quite a few factors such as how much the bristles have frayed, the growth of fungi and bacteria and even any illness that you might face.

But, one thing that you need to keep in mind is that should you face some illness, it is essential to change your toothbrush head once you’ve actually recovered to ensure that there’s no further problem that arises out of it.

These are the main things that you need to keep in mind. But, once again, under ordinary circumstances, 3-4 months sounds like the ideal period of time between which you need to change your toothbrush head, provided that the bristles don’t really get too frayed before that.
