Electric toothbrushes are a modern and thorough way of ensuring optimal dental hygiene in a simple way every day. Dentists also often recommend their patients to switch from a manual toothbrush to an electric model. Studies have repeatedly confirmed a higher cleaning performance .

How does an electric toothbrush work?

An electric toothbrush consists of two parts: the handle, which houses a rechargeable battery or the battery, and the brush head, which is placed on the handle.
If the device is switched on, the head rotates with rapid movements . In this way, both the tooth surfaces and the spaces between them can be thoroughly cleaned.
The brush head moves an average of 7,000 times a minute, depending on the cleaning level. Depending on the cleaning technique, significantly more plaque can be removed in this way than with a manual toothbrush. Food residues can also be removed more easily from the spaces between the teeth and from exposed tooth necks.
For power supply, older models with batteries, such as. B. NiMH batteries that had to be replaced regularly.
Almost all electric toothbrushes are therefore now equipped with a battery that can be recharged using the charger supplied. But even with the models with a battery, there are differences in terms of energy. The service life depends on its type.

Battery performance and types

  • Zinc-air: service life 2 - 3 years
  • Silver oxide: lifespan 3 years
  • Alkaline (NiMH): service life 4 - 7 years
  • Lithium (Li-Ion) : service life up to 15 years
It is therefore worthwhile to prefer a model with an integrated battery and to use a long-life lithium battery. Most devices with lithium-ion batteries are equipped with a charge indicator that shows you when it is time to charge the toothbrush. The integrated battery operation provides a good battery life and can be recharged in next to no time. The best models can hold their charge for several weeks before needing to be charged.
Many of the current models can also be charged with a USB cable , which is particularly useful when you are on the move . If you travel a lot, this type of charging can be particularly practical, as you don't have to carry a separate charger with you.
Special version: travel toothbrush
Some manufacturers offer electric travel toothbrushes that run on batteries and are also small and handy. A travel toothbrush is often supplied with a practical case for transport so that it can be easily carried in the pocket.

What types of toothbrushes are there?

1. Rotationszahnbürste

The oscillating rotary toothbrush is the classic. It is operated (in comparison to normal manual toothbrushes)
with an electric motor through which the brush head can perform the circular movements.
Due to the small size of the brush head, each tooth is brushed individually. Groups of teeth should not be brushed at the same time.

2. Sonic toothbrushes

In addition to the rotation, a sonic toothbrush also performs vibratory movements.
It also differs from the rotary brush in terms of its mode of operation. Instead of an electric motor, these devices are operated with a sound transducer. This enables movements of the brush head that are around 10 times faster than with the rotary brush, so that a very thorough cleaning can be achieved with the right cleaning technique.
In contrast to the small, round head of the rotary brush, the sonic toothbrush has an elongated brush head that can brush several teeth at the same time , which makes it very easy to use.

3. Ultrasonic toothbrush

As ultrasonic dental bust such devices are called, achieved the brush head while brushing vibrations of 300 Hertz and more. If you convert this value to the minute, around 1.8 million vibrations are produced .
No mechanical cleaning method is used with the ultrasonic toothbrush. Rather, the vibrations create a mixture of toothpaste and saliva in which many tiny bubbles form, which explode in the mouth, pulling plaque and food particles with them. This mixture can also penetrate into those places that are difficult to reach with the brush heads.

4. Bluetooth toothbrush

The rotary brush is also available as a Bluetooth toothbrush . It is paired with a smartphone with Bluetooth and connected to a corresponding app.
With such apps, various cleaning processes can be saved and you also receive suggestions on how the cleaning behavior can be improved. An app also makes it easier to discuss how to brush with the dentist and to set up an effective prophylaxis program .

Which toothbrush for kids?

For younger people, too, it is important to brush their teeth thoroughly, starting with the milk teeth. As soon as they brush properly and have learned a reliable technique with the manual toothbrush, they can be instructed to switch to an electrically operated model.
Children's toothbrushes usually have softer bristles than the adult models and are equipped with a handle that fits well in the small child's hand. In addition, the movements of the toothbrush can be dampened so that they are not perceived as uncomfortable in the mouth.

Brush heads

The functionality and quality of an electric toothbrush depends on a good brush head as well as on a high-quality handle. The brush heads have a shelf life of two to three months and should then be replaced at the latest in order to remain hygienic.
In addition to the classic brush heads for hard-to-reach places, there are toothbrush heads whose individual brush elements are shaped in such a way that they are ideally suited for deep cleaning. To match, certain models are equipped with a deep cleaning program.

Buy an original or an alternative?

The brush heads are adapted to the movements of the toothbrushes and therefore you should use original brush heads if possible. Although they cost a little more money, it has been shown that these also last longer than the no-name replacement heads.

The right care for rotary toothbrushes

After each use, it should be rinsed under running water so that toothpaste residue can be removed. The brush head is then dried in an upright position.
At home, you should always leave your toothbrush open. Covering the damp brush head can lead to the formation of bacteria . It is advisable to use a suitable travel case for when you are out and about. Cases that are provided with air holes so that ventilation is guaranteed are particularly practical.
During dental care, you should make sure that the brush is not pressed against the teeth with too much pressure. If the pressure is too high, the bristles will wear out faster. It can also damage the enamel and exacerbate the problem with exposed tooth necks.

How often do I change the brush head?

As a rule of thumb, the brush heads should be replaced every three months . However, if you notice that the bristles appear frayed before this time, the replacement should take place earlier so that the brush can continue to remove plaque effectively.
Some manufacturers offer brush heads where a change in the color of the bristles indicates when it is time to change the brush head. However, it is always important to change sooner rather than later. Worn bristles lose their cleaning power and make brushing your teeth less effective.

Manufacturers and models

Electric toothbrushes are offered by a number of manufacturers and there are also different models from each manufacturer. The price differences between the individual models can also be large. We are now introducing the most popular manufacturers.

Oral B

In tests by Stiftung Warentest, the models in the Oral B series from Braun regularly achieve very high ratings and are therefore often recommended by dentists. First-class results in daily cleaning and good handling contribute to the fact that the Oral B models are always among the first in the test.

Which Oral B is the best?

One of the most popular electric toothbrushes is the Braun Oral-B Genius 1000N . The device was one of the test winners at Stiftung Warentest in 2017. A special plus is that they can be used together with the app for the smartphone, which was specially developed by Oral B to promote efficient dental care.


Philips also offers a large number of models that achieve good cleaning performance. Thanks to technical innovations, Philips always offers new products of the highest quality. Accordingly, Philips is often the test winner at Stiftung Warentest with its top product “Sonicare”.


The AEG brand also offers inexpensive electric toothbrushes. These are characterized by brush heads also high-quality, rounded quality fibers that protect gums and teeth. Most of the AEG models are charged by induction, which is a major difference from the competitive models. Another advantage of the AEG models is the slim design, which helps ensure that the handles sit very comfortably in the hand.


The SB 1000 is popular with customers as an inexpensive alternative. The device is characterized by a simple design and reliable functionality. The selling price is fair and replacement brush heads are also available.


In the field of electric toothbrushes for children, Stiftung Warentest chose the Janosch model from the Beurer brand as the test winner.
Cheaper alternatives to the aforementioned brands should definitely be treated with caution and you should definitely keep an eye on the reviews of other buyers.

Advantages and disadvantages of electric toothbrushes


  • More thorough cleaning than with a manual toothbrush
  • Comfortable, easy to learn handling
  • Different attachments available for special needs
  • Extras such as pressure control and timers contribute to the correct cleaning technique


  • High purchase price
  • Improper use can damage teeth and gums

Dentists recommend the cleaning performance for healthy teeth

Dentists are increasingly advising their patients to buy an electric toothbrush. Practice has shown that they allow thorough cleaning.
An important aspect that dentists emphasize again and again is that gums and tooth enamel can be treated particularly gently. With the manual toothbrush, cleaning consists of mechanical pressure and rubbing, which is superfluous with the electric toothbrush. In fact, there are many models in which the pressure is controlled in order to guarantee that you can brush your teeth gently.

Less pressure on the gums

The strong pressure exerted with the manual toothbrush often leads to bleeding gums, inflammation of the gums and periodontal disease . More thorough removal of bacteria and improved dental health are the result. Tooth decay is also less common.
Some electrical models with the correct attachments are also recommended by dentists for implants, crowns and bridges. The thorough and at the same time gentle cleaning ensures that such dentures last longer. Braces wearers also benefit from the electric toothbrush and, with the right attachment, can thoroughly clean even in tight spaces so that there is no bad breath.

Note when buying

The electric round head brush is the classic


There are numerous inexpensive models that are great for getting started. However, you should note that such a model often creates a wrong impression. As a rule, they are not so easy to use, offer hardly any extras and the cleaning performance is also lower.
Since these models usually have a shorter life expectancy due to poor workmanship, it is usually advisable to take the step and opt for a branded device of top quality.


It is best to first think about which extras are most important.
Many electric models today offer multiple cleaning programs. These are useful because, for example, slow movements of the brush head can be used to massage the gums , while particularly fast movements remove stains and discolorations from the teeth.
Even with sensitive teeth and gums, it is advantageous to have a program available with less rapid movements. Therefore, it generally makes sense to opt for a toothbrush with a choice of program.
The right brushing time is also very important for an electric toothbrush for optimal cleaning. It is of course necessary to distribute the recommended time of two minutes, which is often indicated by the timer, evenly over the four tooth quadrants.
Many models have a timer installed to help the user keep the correct time. Not only the end of the total time of two minutes is given. A buzzing sound or a brief interruption indicates when the quadrant should be changed. Most customers judge this timer function to be helpful and once you get used to it, you usually don't want to be without it anymore.
A very new function makes it possible to connect the handheld device to an app on the smartphone via Bluetooth. For example, the pressure can be checked. Position detection is also possible. You can also use the respective app to receive useful tips on how to improve your toothbrushing technique.

Our recommendation for additional functions:

  1. Slower gum massage program
  2. Faster program for removing stains and discoloration from teeth
  3. Timer that gives you an idea of ​​how long each square should be cleaned
  4. Andruckkontrolle via Bluetooth

scope of delivery

When making a price comparison among the individual models, it also makes sense to pay attention to the accessories that are included in the scope of delivery. While some devices only offer the handle with an attachment and the charger, better models of electric toothbrushes offer several attachments , the charger and often a practical travel case in addition to the handle .
There is not the same selection of attachments for every model and they differ in price and performance.
The brush heads also represent the highest follow-up costs. Therefore, a look at the price for the initial purchase is not necessarily conclusive. While you can buy cheap replacement brushes for some models, they are very expensive for other devices.

The possible scope of delivery at a glance:

  • 1-2 parts
  • 1-? Essays
  • Extra box for the attachments
  • Integrated lithium battery
  • Charger or charging station
  • Travel case

Power consumption

The power consumption depends on the manufacturer and model as well as your own charging behavior. Some users place their toothbrush on the charger all the time. Depending on the model, this can result in higher power consumption than if you consistently only charge the device once a week. Modern chargers switch themselves off automatically and solve this problem
Current electric toothbrushes today only consume one to two watts, which works out at annual electricity costs of around two to four euros. Thus, modern dental care is not expensive in terms of power consumption and it is not necessary to forego the comfort of an electrically operated model in order to save electricity.

Stiftung Warentest

Stiftung Warentest is always a particularly reliable source of information when it comes to impartial test results. The Braun Oral B models have always performed with the best results in various tests in recent years.
In 2015, the Braun Oral-B Vitality Precision Clean took first place with a test grade of 1.1. In 2016 the Braun Oral-B Pro 6000 was voted the best toothbrush with a test grade of 1.5 and in 2017 the Braun Oral-B Pro 3000 delivered the best test result.

Brushing technique with electric toothbrushes

This must be taken into account when brushing with an electric toothbrush
Anyone who switches from a manual toothbrush to an electric toothbrush has to get used to a special cleaning technique. Basically, you should assume that you can brush more thoroughly with electric teeth brushing, but that no time is saved.
Such a device should also be cleaned for at least two minutes. This time should of course be evenly distributed over the four quadrants of the dentition . As usual, cleaning should be carried out at least in the morning and in the evening.
Some models make the work of timing easier with a timer. It indicates with a short tone or an interruption when it is time to change the quadrant.

Teeth cleaning

The cleaning technology is simple and you can leave the actual cleaning work to the electric toothbrush. You only need to guide the bristles along the teeth. The rotary brush has a small, round brush that requires you to brush each tooth individually. To do this, you should make a short stop at each tooth and also take the inside of the tooth and the chewing surface into account.
The pressure involved in this brushing technique should never be too strong to avoid damaging the gums and tooth enamel. With some models there is therefore a pressure control to help with correct use, which indicates that you should apply less pressure by means of a warning tone or a flashing light (i.e. with visual pressure control).
Circular movements of the brush ensure intensive cleaning of the teeth

Complementary cleaning

Electric models clean more effectively than a normal manual toothbrush, but the interdental spaces require additional support from dental floss, interdental brushes or an oral irrigator.
Regular professional teeth cleaning at the dentist's should continue, especially for people at risk of periodontitis.
Cleaning the tongue also requires special additional aids such as B. a tongue scraper, which gently removes deposits on the tongue for even more hygiene in the mouth.
It is always brushed from red to white. The round brush head should therefore be placed on the gumline. The interdental spaces must also be taken into account when brushing your teeth.
If you have gum inflammation, you may experience bleeding gums when you start brushing with the electric toothbrush. But you shouldn't let that deter you. Especially when there is inflammation, it is important to rid the gumline of bacteria . After a week at the latest, the inflammation should subside and the bleeding gums should stop. If the condition lasts longer, you should visit the dentist.
The interdental attachments are also an excellent way of preventing tooth decay. These can be used to thoroughly clean the spaces between the teeth two or three times a week, so that plaque is avoided.

Which toothpaste is the right one?

You can use regular toothpaste that is also used for a manual toothbrush. It is advisable to always use a high-quality toothpaste in order to increase the care effect. In our toothpaste comparison you will find some interesting and special toothpastes.


The market is developing rapidly and new smart devices with interesting additional functions and a wide range of functions are constantly coming onto the market. It depends a lot on personal preferences which of these functions you really want to use. Because these are also reflected in the strongly varying prices.
Experts often recommend using an electric toothbrush on sensitive gums. They are also an excellent way of improving oral hygiene for those who wear fixed braces. These devices are also recommended for implants, crowns or bridges, as they can remove food residues and bacteria even in small spaces.
A comparison of the individual models is worthwhile before buying.
