Electric toothbrushes are superior- getting rid of plaque and gingivitis more effectively – and they are low effort. But the hum of noisy models can be an unwanted alarm clock… or just plain annoying! So what’s the quietest electric toothbrush?
Read this article for the decibel (dB) level of the best quiet electric tooth brushes around.
Along with a noise comparison, we will also give you the lowdown on other neat features worth talking about. But first…
How loud are electric toothbrushes? – the whirring or buzzing of standard electric toothbrushes can register around the 70 dB mark. That’s louder than a microwave and even some robot vacuums, but quieter than a blender. The quieter models we will tell you about here are 60 dB or quieter.

Before we jump into 7 of the quietest electric toothbrushes, here are some stats:
#1 – Oral B iO Series 5 – 64 dB
Quiet electric toothbrush from globally-trusted brand that includes 2 minute timer function and 5 different cleaning settings.
The 64 dB produced by the Oral B iO Series 5 – with noise test done by the excellent Electric Teeth blog – means that it isn’t the quietest electric toothbrush that we found, but it is certainly in the quiet category.
Using gentle micro-vibrations, it utilizes magnetic interaction to deliver a motion that is smooth and harmonious. Reassuringly, reviewers who bought the toothbrush on Amazon confirm that it is indeed a quiet model compared to other Oral B options.
There is a built-in 2 minute timer – an ingenious feature for those who regularly switch off before hitting the time stamp recommended by dentists.
You’ll also be able to choose between 5 cleaning settings – selecting the most agreeable experience for your teeth and gums.
Pros
- Low noise (64 dB) backed up by users
- 2 minute timer
- 5 settings
Cons
- There are quieter options
Best for: Quiet mid-price performer
#2 – Oclean X Ultra S – 45 dB
This is the quietest electric toothbrush which we could find on today’s market, registering only 45 dB while still delivering over 80,000 micro-vibrations per minute. An excellent choice.
Let’s plummet way down the sound scale, into the realm of seriously quiet electric toothbrushes.
Stats from the manufacturer show that the Oclean X Ultra S registers way down at 45 dB, making it the quietest electric toothbrush on this list.
The ultra-quietness is one thing, but now we are going to reel off a series of other cool features that might make you fall in love. There’s a smart touch screen for switching modes, checking the battery, and even getting brushing feedback. An AI voice reminder can offer expert brushing tips (don’t worry, you can also turn this feature off), and perhaps crucially, a high-performance motor can deliver 84,000 vibrations per minute for a super deep clean.
Quiet, smart, and well-designed, there is a lot to like about the Oclean X Ultra S.
Pros
- Very quiet (45 dB)
- High-performance motor
- Smart touch screen
Cons

#3 – Philips Sonicare 4100 – 58 dB
A quiet, reliable electric toothbrush that doesn’t cost the Earth and comes with smart sensor technology and a USB charger.
“Whisper quiet” is how one reviewer described the Philips Sonicare 4100, and at 58 dB, they are not too far wrong.
Tests were done from 6 ft away by the guys at Tech Gear Lab, and the 58 dB registered is a very respectable noise level that is unlikely to disturb anyone in your bedroom.
The truth is, this is a no-frills electric toothbrush that doesn’t represent the latest advances in dental technology. But as you can see above, it’s pretty quiet, and is also no slouch at 31,000 brush strokes per minute and has a smart sensor to help you avoid brushing too hard.
It comes with everything you need, including a USB charger.
Pros
- Fairly quiet (58 dB)
- Excellent value
Cons
- Not the most powerful
Best for: Quiet budget option
#4 – Suri Sustainable Sonic Toothbrush – 54 dB
With its sustainable design, extra long battery life, and slim profile, there is a lot to like about the Suri Sustainable Sonic Toothbrush – it’s also quiet at just 54 dB.
A sustainable option takes a rightful place in this quietest electric toothbrush list.
The team at Tech Radar did some testing, and the Suri Sustainable Sonic Toothbrush registers at a hardly noticeable 54 dB, which makes it one of the quietest models out there.
What about the sustainable bit? This model uses brush heads manufactured from renewable cornstarch, and medium-soft bristles made from castor oil.
It’s also an attractive, slim profile – about half the size of a standard electric toothbrush – which means that it not only looks sleek, but will take up less space in a wash bag when traveling.
Designed in California, it can manage a very respectable 33,000 vibrations per minute, and has an extended 40-hour battery life. Includes a travel case with UV cleaning light.
Pros
- Very quiet (54 dB)
- Manufactured sustainably
- Slim profile
Cons
- Less powerful vibrations that some brushes
Best for: Quiet sustainable option
#5 – Waterpik Sensonic – 45-50 dB
By delivering a low-noise electric toothbrush and water flosser for a ‘complete care experience’, the Waterpink Sensonic sets itself apart from the pack.
Now we come to the Waterpik Sensonic, which comes in a cool package that also includes an accompanying water flosser.
Over at Live Science, they did some testing and found that the decibel level of the Waterpik Sensonic is between 45 and 50 dB – very quiet for an electric toothbrush of this caliber.
The important thing to remember about the Waterpik Sensonic is that it is a ‘complete care’ experience. You’ll get to use an advanced water flosser, which, combined with the electric toothbrush, can remove up to 99.9% of plaque bacteria, according to the manufacturer.
There are 5 flossing tips to choose from, and 2 contour heads for the brush, along with a premium carry case.
Pros
- Tested as quiet (45-50 dB)
- Includes water flosser
- American Dental Association approved
Cons
- On the pricier side (but includes flosser)
Best for: Quiet brushing and flossing combo
#6 – Quip 360 – 54 dB
Quiet operation, a built in pressure sensor, and a 2 minute timer; and don’t forget the carry case – the Quip 360 represents a superb value choice.
The people at Electric Teeth have registered the Quip 360 as having a noise level of just 54 dB. So it certainly deserves a place in this article.
There is a lot of other good stuff to tell you about – timed sonic vibrations switch between 30-second pulses and gentler vibrations, and there is a built-in 2-minute timer to ensure that you are meeting those dental guidelines!
We should mention the built-in guiding pressure sensor with its LED light, which is designed to prevent hard brushing that could damage your gums.
It comes with a travel case and mirror mount, as well as an extra brush head. Oh, and it’s excellent value.
Pros
- Quiet (45 dB)
- 2 minute timer
- Great value

#7 – Triple Bristle Sonic – 58 dB
A patented 3-sided brush design for the purpose of reaching all the right spots with the right angles, a slim grip handle, and a 58 dB noise level which puts the Triple Bristle Sonic in the ‘quiet’ category.
We wrap up with the Triple Bristle Sonic, which Electric Teeth tested as making 58 dB operational noise; comfortably in the quiet category.
It’s not only quiet but it’s clever – with its striking three-sided design, the Triple Bristle Sonic claims to clean your teeth in one third of the time – makes sense, I guess!
With its charcoal-infused brushes, the head is intended to find the right angles for those hard-to-reach places where plaque can often build up without you knowing.
What else? There is a slim grip handle, a sightly black color scheme, and a rechargeable battery that keeps the toothbrush going for one month.
