Ultrasonic toothbrush: how to choose, pros and cons

For healthy maintenance of oral hygiene should be regularly used basic and additional tools. The main include: a toothbrush and paste. At the moment there are a large number of different types of toothbrushes from different manufacturers. Often in everyday life uses a mechanical or ultrasonic toothbrush. Many believe that the use of ultrasound will allow the cleaning process to carry out all the necessary processing. For quality performance of cleaning teeth has its own requirements, which are relevant for brushes with any ultrasound mode of action.

Features of the structure

First invented was a device Robert Side in 1991. After performing several researches scientist came to the conclusion that the use of the ultrasonic brush has a definite therapeutic effect on hard and soft tissues of the oral cavity. The first devices began to sell in Europe, USA, Japan and Canada. Over time, the area of distribution increased in the other countries of the world have started to use the dental products on the basis of ultrasound.

Toothbrush with ultrasound generates vibrational waves that are transmitted through the bristles at the point of contact with the teeth. These waves destroy the plaque, starting the deposits of Tartar. With the help of the waste products of bacteria and poor hygiene of the oral cavity are removed.

Work the brush from the batteries that can be recharged or AA batteries, so these brushes can also be attributed to electric.

Ultrasonic toothbrush consists of a handle and head (working part). Inside the handle is installed on the motor. In the inner part of the head, parallel dental bristles, is located a piezoceramic plate.

When you turn the brush motor on plastic is fed ultrasound wave with a frequency of 1.6–1.7 MHz. This frequency is equivalent to 100 000 000 oscillations for 1 minute.

It is in this frequency range ultrasound wave propagates from the contact point deeper into the tissues of the mouth up to 4 mm. against this background, the effect of ultrasound is not just for teeth but also the tooth-gingival sulcus, contact points between the teeth, the gums, deep pockets in the periodontal diseases.

If you compare ultrasonic brush teeth and sound, the latter there are differences in the frequency of the action. The amplitude of frequencies above the audio devices, but the speed is well below ultrasonic. Oscillations are performed at a speed of 32,000 per minute.

Advantages and disadvantages

Certified ultrasonic toothbrushes are not cheap, and like any product it has its pros and cons. Through the use of ultrasound in the brush work is done the cleanse, in General, not just teeth but other tissues of the mouth. It should also be noted that the physical waves have a bactericidal effect on present mouth microflora. An important aspect of using fixtures is the ability to eliminate plaque, which with a long stay on the teeth are able to transform into dental stones due to the mineralizing function of saliva.

With regards to time brushing the producers in the creation of brushes based on ultrasound, is also considered important aspects. Typically, these devices have 3 modes: minimum, average and maximum. Each of modes is fixed at the time interval of 2 minutes. It is that time necessary for performing adequate oral hygiene. Depending on manufacturer, the overall timeframe can be broken. Most often it is divided into 30 seconds. Change each interval accompanied by an audible signal. This is especially convenient when making a standard way of hygiene by sector: each jaw is divided into half and the cleansing of all parties can be made, starting and ending in one of the quadrants, moving subsequently to another.

Ultrasonic toothbrush is able to provide in use a cleaning the most inaccessible surfaces: a gingival sulcus, the area of the contact point, deep fissures. It should also be noted that the use of devices is possible in persons suffering from hypersensitivity. Patients who have dental braces application is permitted with the consent of the specialist.

Despite having undoubted advantages, the ultrasonic brush has a number of limitations, and this device is contraindicated for:

  • In the presence of a pacemaker: preferences in artificial heart pacemaker can suffer from the effects of ultrasonic waves;
  • Pregnancy and lactation;
  • Inflammatory diseases of periodontal tissues;
  • Oncology;
  • Not recommended for use in the field of crowns, the edges of fillings, veneers and Lumineers: possible violation of the seal in the future.

So before buying merchandise, you should become familiar with indications and contraindications. And it is best to visit the dentist, an appointment which will explain the features of use and efficiency from the application.

Due to what is action

Piezoelectric plate converts measurable from the motor electrical current into ultrasonic vibrations. This mechanical energy has a high coefficient of performance (COP) compared to electric and sonic brushes. Oscillations with a frequency of 100 million Hertz no chance of survival remaining in the oral cavity bacteria. Some manufacturers include operation of the ultrasonic devices are also sound vibrations. The combined effect of the high frequency and low frequency provides additional mechanical impact.

Why, in some cases contraindicated brush with ultrasound? It justifies a restriction of consumption in the presence of mouth structures made of artificial materials (fillings, orthopedic devices fixed type) that when exposed to ultrasonic waves at the point of contact with the tooth faces increases the tension on the border of two heterogeneous materials. This leads to process imbalance that may lead eventually to the violation of Hermeticism, and this in turn can give the opportunity to join the microflora of the oral cavity, which causes the development of infectious process. We cannot say that this limitation is absolute, rather relative. Therefore, with the permission of the expert, of course, to use the ultrasonic brush.

Inflammatory diseases of the mouth, periodontal disease in the active stage of the process are the limiting factor for the use of these devices. This is because when exposed to mechanical supplemented with ultrasound brush there is a strengthening of alternative processes. Excessive use of these brushes in the acute phase, for example, when you initially available the mobility of the teeth can enhance the destructive processes to bones that eventually, if untreated, can cause total loss of the tooth.

Recommendations on the choice of

So, you consulted a doctor a dentist who examined your mouth, gave approval for the use of brushes with ultrasound. The question naturally arises, how to choose an ultrasonic toothbrush the design of their own. Currently there is a large range of devices from different companies made in different countries. Price gradient, depending on the country, the complexity of the device also varies and ranges from 1,500 to 15,000 rubles on average per unit.

Choose an ultrasonic toothbrush and remain satisfied with the quality it should, based on their preferences. It is best to look at the problem holistically choice: should satisfy both quality and price, and aesthetics. Therefore, even if the item costs more than you would like, it is necessary to appreciate the internal parameters of the device.


Recommended brands of ultrasonic brushes:

  • Megasonex;
  • Emmi-dent;
  • Smilex;
  • Donfeel: the domestic manufacturer, in cooperation with Hong Kong.

If you wish to save, you can choose not American-made brush, and Chinese. The price will be much lower but for high quality requirements it is better not to show.

An overview of popular devices

Megasonex may be used for minor pathology of the hard tissues of the tooth (caries, erosion, abrasion), as well as in inflammatory processes in the initial stage. The range of bits is represented by a set of bristles of soft to medium-hard. Tests on pregnant women, cancer patients have not been conducted, so these devices are not recommended without prior tests. The handle shows the battery indicator and ultrasound. You can also adjust the speed of movement of the bristles: 0, 9000 and 18000 strokes per minute. A mounting mechanism of the handle and interchangeable tips reliable. Under the dental attachment is Megacrystal, length 17 mm, which is used to generate ultrasound from the running motor.

Starter brush model «Ultima» from Megasonex not so long ago, was tested in one of medical universities in Tokyo, based on the study of prevention in dentistry. Studies confirmed by photo electron microscopy proved that using only ultrasound generation with frequencies of 1.6 MHz you can achieve break the chain of bacteria at a distance of 5 mm from the working part. Price per unit average of 8500 rubles.

Emmi-Dent works 100% ultrasound. To use apply the paste made from the manufacturer of the brush that comes with the device. The characteristics can be noted that the applied ultrasonic toothbrush can and a non-contact method, providing a therapeutic effect to a depth of 12 mm from the impact point. Application in the presence of foreign materials in the oral cavity (implants, crowns, fillings), periodontal disease in mild form are also possible. The price averaged about 12 600 rubles per unit.

Smilex also very similar in parameters with the above manufacturers. One of the differences from the previously mentioned devices is the presence of a complete set of attachments is not only soft and hard stiffness, but also silicone. Soft is used as a base for cleaning all available surfaces. Hard to cleanse the rear surface of the teeth. The silicone nozzle is used to massage the gingival area. Price around 11000 per unit.

Donfeel operates at a frequency of about 48 kHz, while a minute number of vibrations is about 48000. Tips included three types: standard. Soft rubberized, interdental. The rest of the operation and structural features of the brush is similar to other popular devices. The unit price of 6,000 rubles.

In General it can be noted that the dental industry for ultrasonic brushes will actively develop further. Before you choose a device to clean your teeth on the basis of ultrasound, then visit the dentist to assess the quality of care, requirements for remediation, selection of special tools. You should choose based on the testimony from the doctor, features, price. The optimal ratio of all requirements will allow to receive not only tangible results, but to feel the psychological comfort.
