Electric Toothbrush Vs Manual Toothbrush 2021: (Scientific Research)

Electric Toothbrush Vs. Manual Toothbrush: What Do Dentists And Scientific Research Recommend?

The eternal battle between electric toothbrushes and manual toothbrushes seems to have come to an end; but who is the winner?

Here’s what dentists and dental hygienists thought.

First made in Switzerland back in 1959, today the electric toothbrush is considered an important asset to our smiles. Increasingly efficient and complete, modern electric toothbrushes have come a long way before becoming the most recommended oral hygiene tool by dentists. Today, more and more used by USA/UK/AUS families, smart toothbrushes take advantage of the most advanced technologies to bring all the precision of professional dental cleaning into our homes.

And what about the manual toothbrush? While resisting the massive rise of its electric version, the manual toothbrush continues to lose its leadership position, holding on to what now seems to be its only strength: an extremely affordable price that everyone can afford! However, while the manual toothbrush doesn’t offer the same precision as electric toothbrushes, it is still a great tool for daily teeth cleaning, as long as it is used correctly.


Electric Toothbrushes & Manual Toothbrushes
The generical term electric toothbrush groups a family of instruments with different technologies able to offer oscillating-rotating, sonic and ultrasonic action. To date, several studies have been performed to demonstrate the superiority of electric toothbrushes over manual toothbrushes.


Here are the results and why dentists recommend using an electric toothbrush but don’t demonize a manual toothbrush (not ready to give up your manual toothbrush yet? Then don’t miss the eco-friendly version of bamboo toothbrushes).


According to a survey reported by The Modern Dentist – in a total of 560 records, 21 clinical trials were found to offer usable data in the deeply-analysis regarding the effectiveness of electric toothbrushes, through a total sample of almost 2300 patients.

The results reported here:

21 trials
21 trials reported the so-called plaque index, showing a reduction in plaque in favor of electric toothbrushes, both with oscillating-rotating and sonic movements.
11 trials
11 trials reported the bleeding index, showing that electric toothbrushes – both oscillating-rotating and Sonic – are more effective in reducing gum bleeding than traditional manual toothbrushes.
14 trials
14 trials evaluated the Gum Bleeding Index. In this case, only the 7 trials that considered the sonic motion toothbrush found superior efficiency in reducing gingivitis compared with the manual toothbrush.


Overall Results
The overall results of these trials clearly show consistent evidence in favor of the use of electric toothbrushes. They help to reduce the most common diseases of periodontology.

These important medical findings are likely to influence the recommendations made to patients by dentists and dental professionals regarding toothbrush selection.

WHY is the Electric Toothbrush more effective than the Manual Toothbrush?

More functional and interactive than ever, the latest generation of electric toothbrushes guides us towards the right way to brush our teeth. While the correct use of a manual toothbrush depends solely and exclusively on the way we brush our teeth (which is often incorrect), electric toothbrushes – thanks to smart technology – offer us all the indications we need to carry out correct oral hygiene. This is possible thanks to the following features and functionality:

Built-in Timer

By now, almost all electric toothbrushes have a built-in timer. This allows us to brush our teeth for as long as we need to. Dentists unanimously agree; teeth should be brushed for a minimum of 2 minutes, at least 2 times a day. The timer on electric toothbrushes allows us not only to follow the dentist’s instructions accurately but also to precisely brush each half-arch of our teeth by beeping every 30 seconds.

Pressure Sensor

The pressure sensor is one of the most useful features offered by electric toothbrushes, as it allows us to safeguard the health of our gums. Most gum problems, in addition to being caused by plaque, are caused by poor oral hygiene. Brushing too vigorously can lead to gum recession and cervical wear of the dental collar. The pressure sensor on electric toothbrushes alerts us whenever our hand exerts excessive pressure during daily tooth brushing.

App connected via Bluetooth

The latest generation of electric toothbrushes has adapted to smart technologies by offering dedicated apps that, connected to the smartphone, help us keep track of our daily oral hygiene routine. Have we neglected a specific area of our teeth? The app will point it out immediately, correcting the way we clean our teeth with extreme accuracy.

Different Preset Programs

The preset programs offered by smart electric toothbrushes allow us to take advantage of specific movements for different desired treatments. Often, these are also associated with different replacement brush heads, capable of polishing and whitening the teeth or massaging the gums. While not critical to good oral hygiene, the built-in programs make the electric toothbrush more versatile and comprehensive than the manual version.

Which Electric Toothbrush is Most Effective Against Tooth Plaque?

Healthy teeth and gums that are free of all types of periodontal disease can use any type of electric toothbrush without doing any damage to oral health. Some electric toothbrush models are better suited than others for removing plaque extremely effectively (find out which ones to buy through our guide dedicated to the 12 best electric toothbrushes for deep oral hygiene).

They have a smaller head than a common toothbrush, designed specifically to better reach the most hidden spaces in our teeth. The electric toothbrush with oscillating-rotating movement, now also available with additional pulsating movement (3D technology), is the one most recommended by dentists to remove plaque and food residues. Its effectiveness is made even more effective by the combination with the Replacement Head by Cross Action.

What is Dental Hygiene
But what is dental hygiene? With its sticky and whitish appearance, bacterial plaque is often the main cause of all periodontal tissue diseases. Once deposited on teeth and gums, its harmful effect is activated by its components (microbial flora capable of transforming sugar into lactic acid; particularly aggressive for tooth enamel). If not removed, bacterial plaque triggers a calcification process, leading to the appearance of tartar.

Which Electric Toothbrush is Most Effective Against Gum Disease?

Toothbrushing with an electric toothbrush is effective against gingivitis. Gingivitis is an inflammation of the gums often caused by poor or incorrect oral hygiene. It is usually characterized by swelling, redness, bleeding, and pain in the gum tissue.

To avoid further stress, inflamed gums should not be subjected to mechanical stress. Therefore, toothbrushes with hard bristles and overly aggressive cleanings should be avoided. The most suitable toothbrushes for oral cleaning for gingivitis sufferers are those with sonic technology.

Sonic toothbrushes produce between 24,000 and 60,000 vibrations per minute. These vibrations generate a myriad of microscopic bubbles that – using the mixture of saliva and toothpaste – act deep into the interdental spaces and gum line.

This technology requires no mechanical friction, which is why sonic toothbrush bristles are especially tolerated by delicate or inflamed gums.

What about that manual toothbrush? Do I simply throw it away?


What about that manual toothbrush Do I simply throwing it away

No professional dentist will tell you to throw away your traditional manual toothbrush if you can produce optimal, flawless daily oral care with it. Moreover, the manual toothbrush remains the most economical way for us to take care of our mouths.

However, since more and more people are discovering after a thorough dental examination that the old manual toothbrush is not able to cope with the formation of plaque, tartar, cavities, and other major oral disorders, such as periodontitis and pulpitis, the dentist suggests the use of the electric toothbrush, as it is clinically recognized as more effective than the manual version.

The extensive clinical studies conducted to date have dispelled any doubts! The superiority of electric toothbrushes over manual toothbrushes has convinced even smile specialists, who are recommending them more and more often to improve the quality of their patient's oral hygiene.
Flexible, convenient to use, and decidedly effective, the latest generation of smart electric toothbrushes, along with dental power toothbrushes, represent the new frontier of deep oral cleaning. The various technologies made available by the world leaders in dental hygiene - such as Oral-B, Braun Philips - allow us to choose the model that best suits our needs.


Cheap, mid-range, or top of the range, the electric toothbrush, if used regularly and for the indicated time (only 2 minutes twice a day), will not only improve our smile but will also halve the number of dental appointments, saving us money and allowing us to quickly amortize the cost incurred for its purchase.
