How To Make Electric Toothbrush Quieter

By Ted Gerner | May 29, 2021

Electric toothbrushes can help improve your dental hygiene easily. These are easy to use, effective, and fun devices. However, the noise produced by these toothbrushes can be a bit irritating for many.

If you don’t want to spend any time modding your electric toothbrush, then the best way for you would be to get a new one. The latest toothbrush models vibrate faster and hence make less noise. However, there’s a much more viable way around it.

In this article, we’ll discuss how to make electric toothbrushes quieter. So, let’s get started!

How to Make Electric Toothbrush Quieter?

The first step of making your electric toothbrush quieter would be to find the source of the noise, which can be the head, battery, or body. If the head is making more noise, then you better replace it. To solve the battery problem, make sure it’s not low on charge. Finally, if the body is making noise, then you should wrap it with a washcloth or a towel to muffle the noise.

What Makes an Electric Toothbrush Noisy?

Electric toothbrushes aren’t that sophisticated in technical terms. If you pull one apart, you’ll find only a handful of items in each of them. The major components that facilitate the vibration mechanism in an electric toothbrush are the gears, motor, and cam. A regular electric toothbrush usually vibrates 26 times per second.

As there’s a back and forth vibration in the head of the toothbrush, this can be identified as the main source of the noise. However, sometimes the problem might not be with the head, but with another part of the toothbrush.

There’s a simple science behind the noise of electric toothbrushes. The slower a toothbrush vibrates, the louder its sound will be. This is why it’s important to buy a toothbrush that vibrates fast. Then again, even a fast vibrating toothbrush can vibrate slowly if the battery isn’t charged properly.

If the battery is low on charge, then it won’t be able to provide the required energy for the head to vibrate fast enough. This will cause more noise than usual.

How to Identify the Source of Noise?

As we’ve discussed earlier, the source can either be the head, the body, or the battery. It’s important to identify which part is the main reason behind this first, or you won’t be able to reduce the noise. We highly recommend using the process of elimination for determining which part is creating the noise.

First, it’s recommended to take a look at the battery charge. You should try charging the electric toothbrush for a while, and if this fixes the noise problem, then you won’t have to spend a penny extra.

However, if that’s not the case, then you should check the head of the toothbrush. Is the toothbrush being used for months? If so, then you should definitely change the head. This will not only keep the noise low, but it’s also very hygienic to do so.

If the noise still persists, then the problem is with the handle or the body. Sometimes, there are problems with the wiring inside the body of the toothbrush, and these can be fixed with some effort. We’ll go further into this later in this article.

How to Change the Brush Head?

People usually find that the brush has been used for far too long, and this is the principal cause behind the noise. In this case, you need to change the brush head, but at first, you’ll need to buy a new one for yourself.

When getting yourself a new brush head, get one from the same brand, or it won’t support your brush. Once you have one, simply remove the brush head. Most of the brush heads are attachable and detachable, meaning that you won’t require any tool for taking them off or installing them. Most of them come with a screw-in design, while some of them will just pop off.

Remember how you took the head off and attach the new one in the same way. The best way of making sure that the handle and the head are joined properly is by turning the brush on. Once it’s turned on, check if the head pops out or dangles from the handles.

If it remains firmly on the handle, then you’re good to go! This is one of the easiest ways of fixing the noise problem of your electric toothbrush.

How to Fix the Body of the Electric Toothbrush?

In very rare cases, it’s found that the noise is being caused not by the head or low battery, but because of the wiring inside the electric toothbrush. These aren’t technically perfect tools, and the components inside them will decay over time. There’s a huge chance that the wiring will get messed up too, because the brush shakes continuously, and some wires may come off.

To find out if this is the main problem, you need to take the brush apart and check for disconnected wires. If you come across any, simply take a soldering gun and put the wires back together. If you’re new to soldering, then this can be a bit tricky for you. However, there are tons of tutorials online, and learning it doesn’t take much effort either.

Try Wrapping the Brush

If none of the solutions given above work, then there’s a chance that your brush is really broken. In such a case, you can try the simplest solution out there. Just try wrapping the brush with a towel or a thick cloth. You can also use your t-shirt for this, but the thicker the cloth is, the more the noise will be reduced.

However, this isn’t a permanent solution, and it can get on your nerves as you’ll need a towel or a cloth every time you use your brush. Some may try making this solution permanent by wrapping the brush with cloth permanently. However, doing so will only make things worse. This will not only hamper the charging process, but it’ll also pose a fire hazard!

This is why you can try getting a new and quieter brush if the problem really bothers you.

Frequently Asked Questions

How Often Should You Change the Brush Head?

If you’re using an electric toothbrush, then you should change the brush head once every 3 months. This will not only keep the brush good as new, but this habit is much more hygienic than using the same brush for months.

Is It Possible to Replace the Battery of Electric Toothbrushes?

It all comes down to the individual model when replacing the battery of the electric toothbrush. If the battery is replaceable, then you should replace it when the battery is showing certain symptoms. For starters, if the battery isn’t providing a long service as before, then it’s probably the right time to change it.

Should You Switch Back to Manual Toothbrushes?

Well, the majority of the world population is still using manual toothbrushes. However, that shouldn’t influence you to revert back to normal ones. It’s true that normal toothbrushes are far quieter than electric ones. However, these are also slower.

So, if you want an effective and at the same time fast brushing experience, then electric toothbrushes should be your go-to, noisy or not.


In the end, it all comes down to your dental health. You may be suffering from a noisy electric toothbrush, but it’s still better than the quieter and regular ones most people are using. Then again, the noise issues can be fixed in a second, unless it concerns soldering the wires. If you have experience doing that too, this task won’t pose a challenge to you.
