TOP 4 Quietest Electric Toothbrushes – 2021

Whether it is the morning or night, a quiet electric toothbrush makes a lot of sense for most people. As more and more people turn to electric options, they pretty much accept the fact that there is going to be some sound. The more pleasant it can sound, the easier it is to brush teeth and be very efficient.

Toothbrushes come with many features, but finding one that is also quiet is a goal for many. These toothbrushes below are all great options to consider for people who want to have a pleasant overall experience.

It all starts with a very fast head that oscillates 400 times per second. Since it moves so quickly, it keeps things quiet when brushing.

It has solid casing made of premium material that helps kill sound coming from the motor as well. Compared to other Oral-B options, they make sure that this toothbrush is a bit quieter right out of the box.

Anyone looking to save money and still purchase a high-quality toothbrush that stays quiet should look at this option from Fairywill.

They have put together a nice sonic toothbrush (Amazon) at a price that most can afford. It might not have the brand recognition of others out there, but all the reviews online have nothing but great things to say.

Each brush head that comes with a toothbrush vibrates at an extreme speed of 40,000 times per minute. With something moving that much, it might seem like it would get noisy, but that is not the case at all.

The company knows that for it to compare and even beat out some of the top toothbrush brands, they need to keep things as quiet as possible.

The toothbrush does feel a little bulky in hand, but that is a good thing as far as controlling sound as concerned. Having an extra bit of insulation surrounding the battery and motor can keep things fairly quiet.

There are a few different toothbrushes from Philips that could make this list, but right now the Sonicare 5100 (Amazon) really stands out.

With 31,000 brushstrokes a second, the noise level does not get very high at all. It can operate very efficiently, which helps a person gets all parts of the mouth in record time.

It should surprise no one that a cheaper electric toothbrush is probably going to sound a little louder than a more expensive one.

Gunk can start to build up on a toothbrush so much that it does not even spin the same way as before. Do not let something like this really start the hamper effectiveness.

Rinse Out The Toothbrush Each Time

One of the ways to prevent gunk from building up too fast is to rinse the toothbrush a little longer each time.
