What Are Sonic Electric Toothbrushes, and Why Are They Essential?

The dental hygiene landscape has changed dramatically during the past few decades. More people have access to oral healthcare today than ever before. 

Oscillating-rotating electric toothbrushes are now available to up your oral health routine.. However, a more advanced version has arrived: the sonic electric toothbrush.


What are sonic toothbrushes?


According to a Journal of Oral Hygiene & Health study, a sonic electric toothbrush emits ultrasound and sonic waves to vibrate the brush. It has a lower amplitude of motion at a higher frequency generated from a piezoelectric crystal embedded inside the hilt of the brush. The sonic waves massage the salivary glands, which increases saliva flow and assists with cleaning teeth. It gives the sonic electric toothbrush a lot of cleaning power and that iconic hum caused by its audible vibrations.

Many sonic brushes can sync with an app to track your brushing behavior. The duo can help you spot missed areas by monitoring where and how you brush using sensors and advanced algorithms.


Difference between oscillating-rotating and sonic toothbrushes


Since powered mechanisms drive both oscillating-rotating and electric sonic brushes, you can easily misidentify one for the other. Nevertheless, many factors differentiate the two. Some of the most noteworthy ones include:



An oscillating-rotating electric toothbrush relies on an electric motor to power the brushing motion. On the other hand, a sonic toothbrush is a rechargeable toothbrush that depends on an ultrasonic resonator as it vibrates to power the stroke. In simple terms, an oscillating-rotating toothbrush moves while a sonic toothbrush vibrates.



With an oscillating-rotating electric toothbrush, you can get stroke speeds in the range of 2,500 to 7,500 strokes per minute. Thanks to its high-frequency technology, those speeds can reach up to 30,000 strokes per minute with a sonic toothbrush.



Oscillating-rotating toothbrushes do a great job mixing water, saliva, and toothpaste to act as a cleaning agent. Sonic electric toothbrushes are made efficient by transmitting the vibrations through that mixture. It allows for removing plaque and cleaning hard-to-reach areas of the mouth.



Oscillating-rotating toothbrushes require soft bristles and excellent battery life. With sonic toothbrushes, you need to keep an eye on the configuration as well. It is almost like checking in with your dental professional every few months.


Benefits of a sonic electric toothbrush


The introduction of sonic toothbrush technology into your life can bring you many oral hygiene benefits. A few crucial ones include-


Faster thorough brushing

The high frequency of vibrations allows sonic toothbrushes to rapidly clean your teeth, gums, and tongue. Most of them are soft bristle electric toothbrush variants, reaching widths close to 0.01 mm. Such thin strands can quickly get to the more delicate parts of your mouth to clean them thoroughly. You only need to look at Colgate Gum Care Heads to observe the sensitivity of sonic toothbrushes.


Less physical effort

Brushing your teeth is not usually regarded as a physically demanding activity. Yet, it can be more strenuous for disabled or physically injured individuals. It is the reason why many would prefer the sonic toothbrush, as it does most of the cleaning work on its own without having to bristle hard all across your mouth.


Less susceptible to diseases

A healthier mouth means fewer bacteria and plaque build-ups. It can lead to better resistance against diseases such as gingivitis and halitosis. Dental health professionals often prescribe electric toothbrushes to people with underlying dental hygiene issues.


It fits multiple gum types

Sonic toothbrushes allow for a variety of highly customizable modes. It makes it easier to configure your toothbrush according to specific dental needs. The delicate functionality makes them perfect for people with sensitive gums. Additionally, patients with recovering ailments can adjust the settings over time to fit their developing needs.


Choosing the right sonic toothbrush


According to the WHO, oral diseases affect nearly 3.5 billion people worldwide. Most of them are treatable early and utilize better daily dental care. It is why you must equip the toothbrush that provides the best oral care daily.

Choosing the right toothbrush is just as important as developing a good oral care regimen. Consider handle style (it should feel comfortable in your hand), head shape, and type of bristles. A toothbrush with a small head makes it easier to reach every spot in the mouth. And soft bristles will clean your teeth without damaging your gums or enamel.

Proper brushing technique


Whether you opt for a sonic toothbrush or not, make sure you brush correctly to provide the best care for your teeth. Use short, gentle strokes, and pay extra attention to the gum line, back teeth, crowns, fillings, and other vital areas. Clean specific sections in the following order:


  • The outer and inner surfaces of upper teeth, then lower teeth

  • Chewing surfaces

  • Tongue to keep your breath fresh


Once you have brushed for two minutes, do not forget to floss! Remember to change your toothbrush (or toothbrush head) every few months and immediately after recovering from a cold. Whichever toothbrush you prefer, make sure you schedule professional cleanings with your dental professional at least once a year.


Are there any side effects of using a sonic electric toothbrush?


As sonic toothbrushes cater to even the most sensitive teeth, there are no side effects from their use. As per clinical research, the safety assessment after six months of regular use of sonic electric toothbrushes indicated no soft tissue abnormalities. It also discovered that sonic electric toothbrushes remove three times more plaque than a manual toothbrush. They are also better at reducing gingivitis and sulcular bleeding. 




In a world quickly becoming more populated with intelligent devices, it is about time that our hygiene products became more ingenious as well. Regular oscillating-rotating electric brushes can only ensure so much in terms of oral care. With sonic electric toothbrushes, you have not only the perfect solution for your daily dental needs but also something that helps save you considerable time and resources long-term.
