How does a sonic toothbrush work? Tips from the factory

Date:2022-01-08 10:20

What does sonic toothbrush mean?

Sound technology is considered to be the further development of the electric toothbrush. In addition to the oscillating movements, it also works with vibration.
 

Vibrations per minute

Thanks to the sonic technology, the brush head swings with 30,000 - 40,000 movements and 8,800 sideways movements per minute. The oscillation rate is 300 Hertz. It is around 10 times faster than the electric toothbrush . It works with a sound transducer that can reach higher frequencies than the oscillating electric motor.
 

Which brush heads fit?

The bristles can be varied according to their hardness and length so that, on the one hand, the tooth enamel is not damaged and, on the other hand, a more pleasant feeling is created in the oral cavity, depending on whether the user has sensitive teeth, for example.
 
The cleaning body of the brush with sound is classic, similar to the ordinary finger toothbrush or specially shaped for sensitive teeth that already have diseases of the tooth neck, inflammation of the gums or even tooth decay. Corresponding interdental brushes ensure interdental contact with the tooth.
 
For good dental hygiene, it goes without saying that the brush heads should be changed from time to time (about every 3 months). On the other hand, you should never clean a brush head in the dishwasher. By the way, UV light can also kill bacteria, but not all mold cultures on the brush head.
 

How long does the battery last?

The sonic toothbrush usually has a lithium-ion battery (Li-ion battery). This differs from classic nickel-metal hydride (NiMH batteries) batteries in that it has a longer service life, better charging behavior and more power.
 
The battery life lasts between approx. 30 minutes and 3 hours , depending on the device and the cleaning level used . In practice, this means that the battery only needs to be charged at the charging station after about two weeks on average if it is used daily.
 
Some brands, such as Philips, have come up with a USB travel charging case for charging with a practical USB adapter for people traveling with laptops. If there is no power outlet near you and the battery just happened to be empty, USB is a welcome alternative in this case too

Efficacy studies for the gums

The sonic toothbrushes presented by us can have positive effects on the gums. One of the reasons for this is that it ensures that the toothpaste penetrates better into the spaces between the teeth.
 
As a result, there are fewer bacteria in the mouth and plaque or gingivitis (inflammation of the gums) can be prevented. It can also remove discolouration from food and luxury goods (nicotine, red wine, coffee, cola ...).
 
According to a study  on cleaning performance carried out by Stefan Zimmer, there has been a significant improvement in oral hygiene on the posterior teeth. This is because the posterior teeth are more difficult to reach with a traditional brush.
 
Caries was also prevented more often, as it is most likely to develop on the posterior teeth. The study also demonstrated that the sonic toothbrush removal rate was three times greater than normal manual toothbrushes.
 
Also , this study of dentists confirms the increased efficacy in reducing plaque and bacteria compared to a manual toothbrush.
 
In the summarizing comparative study carried out by Philips, a table shows the standardized average increase in efficiency in the removal of plaque and gingivitis. The results of the examination results listed there show a consistently positive balance.
 
Another advantage for the user is that cleaning errors can be corrected . If you do not master the optimal cleaning technique, you should rather use a sound technique.
 

Supplement to brushing your teeth

As with the usual manual toothbrush, dentists recommend other dental care products such as dental hygiene products as a supplement to brushing your teeth. B. a mouthwash or floss cleaning. A dental chewing gum is ideal when you are on the go and consumption is not limited to healthy foods, but a higher proportion of sugar finds its way into your mouth.
 
Regular professional teeth cleaning at the dentist supports the care of the teeth, especially where the tooth and gums are in contact. You can save money depending on the amount of additional dental insurance if you have this done every 6 months.
 

Which toothbrush is best?

Both types have some advantages and disadvantages due to their design. We would like to make your decision easier and are now comparing the two operating modes.
 

The classic electric rotating toothbrush

As the name suggests, the rotating electric toothbrush is an electric toothbrush. This has to show an electric motor, which makes the brush head rotate. The plaque is easily scrubbed off and a very good mouthfeel is created.
 
The speed of rotation of the brush head movements per minute can reach up to 8,800 rotations . As with the sonic toothbrush, it depends on the individual product.
 
The biggest difference is that sonic toothbrushes vibrate and move sideways, while electric toothbrushes make circular movements. Your transducer generates 30,000 - 40,000 vibrations per minute. So they reach a higher frequency than an electric motor and are about 10 times faster.
 

Differences in shape

Externally, sonic toothbrushes often have a larger handpiece and an elongated brush head, while the electric toothbrush is only equipped with round brush heads. Exceptions to this are “slim” models, such as the Pulsonic Slim One 1000, which attach particular importance to compact dimensions and yet lie comfortably in the hand.
It also makes it easier to use, as it does not have to be brought up to each individual tooth. The rotating electric toothbrush works with a smaller brush head. Therefore, each tooth has to be cleaned individually.
 
Overall, a better result in oral hygiene speaks more in favor of a sonic toothbrush, as it offers more intensive cleaning and is also easier and safer to use and is gentle on the gums.
 

Disadvantages of sound technology

Depending on the brand, a sonic toothbrush is usually more expensive than a classic electric toothbrush. However, many price comparisons show that the difference in prices has narrowed. Sound technology is still more expensive to buy, but there are more and more functional entry-level products, such as the AEG EZS 5663 or the Philips Sonicare Easyclean models.
 
The high-frequency noise during operation is also annoying to some users. Since the brush heads are larger, it is also a little harder to get to the molars.
 

Complementary dental care

In both types, there is no one hundred percent dental care, so you also need other hygiene products for dental health. The dental floss should not be missing in any household, once you get the hang of it, you can use it to clean the spaces between your teeth quickly and safely.
 
An alternative would be interdental brushes, which, if they are not disposable products, can usually be used for up to 14 days. The brushes, which can be bought in various sizes, are very easy to get into between the teeth and their efficiency has been proven in studies .
 
Many customers also rely on the oral irrigator. However, this does not replace dental floss or interdental brushes, and neither does brushing your teeth. It is best to work first so that the teeth are brushed, then dental floss / interdental brushes are used and the irrigator is used to rinse even the smallest residue out of the gaps. Then another mouthwash and the teeth were ideally cared for.
 

Ultrasonic toothbrush

An ultrasonic toothbrush differs in the way it is used and how it is cleaned. The technical data say that it performs around 1,600,000 vibrations per second, depending on the model. That is 96 million vibrations per minute. The ultrasonic toothbrush also works with 0.6 watts. At a frequency of over 300 Hertz , one speaks of ultrasonic toothbrushes.
 
This method of dental care is so special because there is largely no contact between the tooth (flesh) and the brush head.
 
Depending on the sensitivity of the teeth and the gums and if you are suffering from periodontal disease, an ultrasonic toothbrush can also be a closer choice.
 
The higher price and the low- contact type of cleaning, the so-called " abrasion-free removal of bacterial plaque " are unique to this type. However, there may be less intensive daily cleaning of the interdental spaces.
 

The right toothbrushing technique?

It is important in advance that the focus is on thorough cleaning. The nature of the toothbrush is therefore less important than how it is handled.
 

Different cleaning levels

The cleaning stages are very important. For effective cleaning, the sonic toothbrush should have at least two. There are different programs. To explain these modes, the Sonicare DiamondClean from Philips , which offers five cleaning levels, will serve as an example. It has five cleaning programs:
 
  • The DiamondClean's clean mode is the normal program that ensures that oral hygiene is completed after 2 minutes. It is considered the standard mode.
  • The White mode provides in DiamondClean for the removal of discoloration of the tooth surfaces and are a further 30 seconds to polish the front teeth.
  • The GumCare mode is said to improve gum health as it gives the user an extra minute to massage the gums.
  • The Polish-mode is a fast program that includes a minute and whiten the front teeth and to polish. This is a special feature of the Sonicare sonic toothbrush DiamondClean.
  • Finally, the sensitive mode is a variant of the clean mode in the Diamondclean. However, this is more careful and is therefore particularly suitable for sensitive teeth and sensitive gums.
     

The right brush head for your teeth

The selection of the brush head should be tailored to the user. In addition to the standard models, there are also special heads with longer bristles that get deeper and better into the interdental spaces that are difficult to reach.
 
Other brush heads are characterized by a larger surface and others with very soft bristles, which are specially designed for sensitive gums.
 
With this selection, the user should consider his personal preference depending on cleaning performance and comfort. Newly developed three-headed toothbrush heads also improve dental hygiene, as the study mentioned above has shown.
 

Other recommended features

An integrated timer is an advantage. The timer gives signals when certain areas in the oral cavity have been sufficiently processed. It shows when sufficient teeth cleaning (recommended cleaning time: 30 seconds per quadrant) has taken place. Another useful addition is a pressure sensor that emits tones if the user presses too hard.
 
Another useful property relates to comfortable handling. An ergonomically shaped handle should be covered with rubber so that it lies comfortably in the hand and may not appear slippery.
 
In some models, an Easy Start program is built in as a further upgrade . This is an advantage for beginners and helps to get used to the new cleaning technique in the first 14 applications. This is particularly useful and convenient for users who have difficulties with new and / or foreign technology.
 

Which models are recommended?

Philips is a pioneer in sound technology. With the patented Philips Sonicare Flexcare line, the company is considered to be the founder of toothbrushes with sound. So it is hardly surprising that our comparison table, as well as the results of the Stiftung Warentest and Öko Test, are dominated by the German quality brand.
Well-known model series from Philips with many convenient features include Philips Sonicare Diamond Clean Smart, Philips Sonicare Healthy White (for whiter teeth), Philips Sonicare Flexcare Platinum and Philips Sonicare Protective Clean.
 
The Oral-B Pulsonic Slim Luxe series is one of the convincing Braun Oral-B models. The Pulsonic Slim Luxe 4100 creates more than 31,000 vibrations per minute and therefore in the most important point, the speed of a Philips Sonicare in no way.
 
Nevertheless, there are also manufacturers such as Panasonic or Happybrush, whose products were also convincingly assessed in the test by Stiftung Warentest or other real tests. The Happybrush Vibe 3 received not only convincing performance but also praise for its design. All of our presented models are characterized by a good price / performance ratio.
 
You can also buy models with sound technology from other manufacturers such as Lächen that have very good customer ratings. The Sonic Power surface, for example, has a high-quality finish with various cleaning modes despite the low price.
 
We would now like to answer the most frequently asked questions to make it easier for you to find the right model for you.

Frequently asked questions

Is there a sonic toothbrush for children?

Yes, there are already those too. The manufacturers pay attention to the sensitive children's teeth. It should have a rubberized brush head. A very popular product is the Philips Sonicare for Kids.
 
However, a child should be able to brush their teeth before they can get a sonic toothbrush. The best thing to do is to go to the dentist with your child and ask what they think about this topic.
 

Which toothpaste to use for a sonic toothbrush?

You can use any common toothpaste. This has been confirmed to us by various manufacturers. You can also just try out how the toothpastes spread and foam up in your mouth.
 

Which toothbrush for tartar?

Sonic toothbrushes can no longer help with existing tartar. They can only be used preventively, like all other toothbrushes on the market.
 

Conclusion

The variety of models is growing steadily and new additional functions are constantly coming onto the market. The sound technology shows a clear difference to conventional toothbrushes and also overtakes purely electric models. They are characterized by increased oral hygiene and easier handling. With a sonic toothbrush you save yourself incorrect cleaning and experience more variety thanks to the different cleaning modes.
 
Ultrasonic toothbrushes are particularly worthwhile for sensitive gums, crowns, implants or fixed braces. However, there are few providers and few studies. No scientific tests have proven whether ultrasound is harmful, but according to several opinions, it should not have any effects.
 
If you are sure that you are using the right technology with your manual toothbrush and do not value the comfort of a sonic toothbrush, you can stick to it without any problems.
 
It is important: If you have problems with your teeth or gums, you should definitely visit a dentist. He can also help you choose the right product. Because not every type of toothbrush is equally recommended for all teeth and for every gum.
