Are Ultrasonic Toothbrushes Better than Manual Tooth Brushing?


Nowadays it’s hard to escape advertisements for ultrasonic toothbrushes; all proclaiming that they are needed for the best home care oral hygiene. They even claim that they are better than manual toothbrushes, removing more plaque and bacteria than a regular toothbrush.

But do ultrasonic toothbrushes work better than regular manual toothbrushes?

Are they better for your budget and overall oral health? We’ll look at what an ultrasonic toothbrush is and what the pros and cons are.

What is an Ultrasonic Toothbrush?

An ultrasonic toothbrush is a higher-powered electric toothbrush for daily use designed to eliminate plaque buildup and harmful bacteria. These electronic toothbrushes use ultrasound, using a series of movement and pressure operating at a high frequency to aid teeth cleaning. The frequency works at a vibration that is beyond human hearing capabilities.

How Do They Work?

The ultrasound moves the bristles on the brush at a high speed and pressure. As you are brushing, the toothbrush head vibrates causing the bristles to rotate. Because of this movement and speed, and as you move over the surface of your teeth, the toothbrush scrubs and eliminates more plaque than a normal toothbrush would. s


Effective at Removing Plaque

Studies looking at the effectiveness of manual brushing versus ultrasonic brushing have shown that electronic/ultrasonic toothbrushes remove more plaque than regular manual toothbrushes. A review of studies showed that by using an electronic toothbrush plaque was decreased by 21 percent just after three months of use.

Timed Brushing

Ultrasonic toothbrushes have a timing feature that helps guide you in how long to brush your teeth for. This feature works to promote adequate time brushing, to optimize the removal of plaque from your teeth and gums.

Does the Work for You

As the brush head moves on its own, ultrasonic toothbrushes are great and easier to use for kids and those with limited mobility. The toothbrush does the hard work, no longer compromising oral health for those individuals.

Works Well with Braces

Ultrasonic toothbrushes are great for those with braces and other orthodontic appliances. Where brushing was typically a difficult task, electronic toothbrushes make it easier and can improve oral health.


More Expensive

Electric and ultrasonic toothbrushes cost more than manual toothbrushes. The price for ultrasonic toothbrushes range from $15-$300 and replacement brush heads typically come in multipack that range from $10-$50. Brush heads are needed to be replaced every 3 months and finding the correct brush head replacement might be difficult. Not all stores carry them or the correct brand. They are available online, however this option might not be convenient for everyone.

Complaints of Destroyed Enamel

In some cases, ultrasonic toothbrush users have complained that they have experienced more sensitive teeth and gums after use. Claiming that the brush movement is too vigorous causing damage to their enamel and making their gums bleed. In these cases, dentists might advise to switch to a manual toothbrush.

Difficulty in Traveling

Certain ultrasonic toothbrushes may pose a problem when traveling, such as plug-in versions. Depending on the charge and how long you’ll be traveling for, your toothbrush might run out of charge while traveling.


Ultrasonic toothbrushes remove more plaque and harmful bacteria than manual toothbrushes. They are easier to use for kids and those with limited mobility and can aid in brushing with their timing feature. However, ultrasonic toothbrushes are more expensive, can be difficult to travel with, and can possibly damage enamel. It is best to consult with your dentist to decide which option is best for your overall oral health.
