Are ultrasonic toothbrushes harmful to teeth or not? Find out if there really is cause for concern in this post.

Since ultrasonic technology for tooth brushing is still relatively new, there are still doubts and uncertainties. Among other things, interested people repeatedly ask whether ultrasonic toothbrushes are harmful or dangerous.

In today’s post, I have addressed this very question. Read on to learn how ultrasonic toothbrushes work and what to look out for when using them.

Among other things, you’ll find the following topics in the text:

For all those who are worried, right away a warning: brushing your teeth with an ultrasonic toothbrush is not harmful – quite the opposite.

The ultrasonic technology

Many people think of ultrasound as “high frequencies” that affect electrical devices or the body’s senses. Since ultrasound can neither be heard nor seen, there is a mysterious meaning attached to the term

In fact, ultrasound is widely used these days and can be found in quite a few areas.

Bats use ultrasound for tracking just as submarines do, many parking aids in cars rely on ultrasound technology, and ultrasound is used very frequently in medicine in particular. Even trees are capable of producing ultrasound.

These examples show how widespread ultrasound is today, and none of the applications listed are in any way dangerous to humans.

Ultrasonic toothbrushes do not use ultrasound

Purely technically, ultrasonic toothbrushes do not rely on ultrasound. Rather, a sound generator is used to achieve the highest possible frequency vibrations of the brush head

The Emmi Dent is one of a few ultrasonic toothbrushes on the market.

Ultrasonic toothbrushes are the successors of sonic toothbrushes. To continue the introduced and established concept of sound, the new generation of toothbrushes has been named “ultrasonic toothbrush.”

Good sonic toothbrushes achieve between 30,000 and 50,000 movements per minute, while ultrasonic toothbrushes achieve between 900,000 and 1.6 million.

Functional principle

While the vibrations of the brush heads in sonic toothbrushes cause rapid, rubbing cleaning, ultrasonic toothbrushes manage without friction.

  • Gentle and effective cleaning
  • About 2 weeks of battery life
  • 96 million vibrations per minute

The interaction of high frequency of movement, saliva and toothpaste forms bubbles that burst in the oral cavity, removing plaque and plaque from the teeth.

This also happens in interdental spaces and zones that you cannot reach directly with a toothbrush.

Good to know: Since there is no friction, ultrasonic toothbrushes are gentler on teeth and gums than sonic toothbrushes.

Harmless brushing technique

Be careful not to apply pressure to teeth and gums with your ultrasonic toothbrush. The technique eliminates the need for mechanical movements.

For sensitive teeth, ultrasonic toothbrushes are a good alternative for gentle but thorough tooth cleaning.

Ultrasound at the dentist

Many dental offices have long used ultrasonic technology to clean teeth. It can even remove plaque that is stuck.

However, the ultrasonic devices in dental offices have much higher frequencies than the toothbrushes of the same name.

Are ultrasonic toothbrushes harmful to those with a pacemaker?

People with a pacemaker are often especially wary when it comes to ultrasound. There is a fear that ultrasound can interfere with the pacemaker’s function.

However, when using ultrasonic toothbrushes, there is no danger whatsoever for people with pacemakers. This has been proven by various studies.

Are ultrasonic toothbrushes harmful to children?

Due to the special mode of operation, the use of ultrasonic toothbrushes is not recommended for children. However, this is based on the special brushing technique.

Ultrasonic toothbrushes are not harmful to children, but more suitable are special electric toothbrushes for children.

Are ultrasonic toothbrushes harmful for implants or braces?

quite the opposite. Because there is no friction involved in cleaning teeth with an ultrasonic toothbrush, they are particularly gentle and gentle.

Sonic toothbrushes like the Megasonex M8 are among the best electric toothbrushes for braces wearers.

For braces, the bursting bubbles develop the cleaning effect even in the areas of the braces that the brush head does not reach.

Are ultrasonic toothbrushes harmful to tooth enamel?

Ultrasonic toothbrushes are less damaging to tooth enamel compared to sonic toothbrushes and manual toothbrushes. Since there is no friction, the enamel is not eroded or damaged.

For all other types of toothbrushes, experts recommend not exceeding two minutes of brushing time, as too much friction can damage tooth enamel.

With an ultrasonic toothbrush, on the other hand, there is no time limit at all when brushing your teeth.

The M8 ultrasonic toothbrush represents the 1st choice for those with sensitive gums.

Conclusion: ultrasonic toothbrushes are not harmful

Because ultrasonic toothbrushes do not use real ultrasound, they are absolutely harmless for home use

It’s worth reading this post about proper brushing techniques for ultrasonic toothbrushes to get the most effective use out of your toothbrush.

  • Currently, ultrasonic toothbrushes are primarily popular among people with sensitive gums due to the gentle and smooth cleaning.
  • If you have no problems, you are free to use any available electric toothbrush.

Many studies have proven that cleaning your teeth with an electric toothbrush is much more effective than brushing with a manual toothbrush.

Criticism of ultrasonic toothbrushes

In contrast to many experts who praise the gentle cleaning of teeth by ultrasonic toothbrushes, other sources also repeatedly point out that there are still no sustainable scientific studies on the cleaning performance of these toothbrushes.

Since the cleaning effect of ultrasonic technology has not been proven, there are also very critical voices.

Ultrasonic specialist Andreas Heinemann was quoted in the Rheinische Post as follows:

“In the conventional cleaning process, water, foam and air are between the brush and the tooth. The cleaning bubbles form, however, only in clear water. In addition, the tested brushes do not generate the frequency necessary for cleaning, so there is no cavitation. In my opinion, customers are being taken for a ride.”
