Sonic and ultrasonic brushes can be confused due to their similar names. But they have different operating principles. In this article we will look at how they differ, how to choose one brush or another, and what are the pros and cons of these technologies.
What kind of device is this?
An ultrasonic toothbrush is a device that allows you to clean the oral cavity with a minimum of effort. The cleansing effect is achieved through the action of ultrasonic waves on the bristles of the brush and the surface of the dental and periodontal tissue.
Under the influence of ultrasound, bacterial deposits are loosened. The waves also affect the villi, causing them to vibrate at high frequencies, which facilitates the rapid removal of crushed plaque from the crowns.
This device is classified as an electric toothbrush, as it can only operate on mains power or batteries.
As a rule, most brushes have several operating modes and different types of replaceable heads. Basically, the device is equipped with a standard, intensive and gentle cleaning mode. The attachments included in the kit differ in the stiffness of the bristles and sometimes in their shape.
An ultrasonic brush is used in the following cases:
- with voluminous bacterial deposits and the presence of tartar ;
- as prophylactic after a whitening or professional cleaning procedure;
- with pronounced pigmentation of the crowns , resulting from smoking or consumption of coloring products. It actively breaks down old pigments, destroying them at the cellular level.

Sequence of application
Remember! When using a sonic device for cleaning, you should adhere to several rules for the operation and sequence of use of the product:
- To quickly get used to the device, during the first two weeks after purchasing it, gradually increase the speed of movement of the villi .
- For the first 30 seconds, use circular movements to clean the front teeth located on the lower jaw, then on the upper jaw. After this, you need to brush the back and forth teeth with a back-and-forth motion.
- Carry out the procedure for no more than three minutes - this is enough to thoroughly clean the oral cavity.
- Change removable attachments every 3 months to prevent the spread of bacterial flora.
Operating principle
Inside this device there is a piezoceramic plate and a motor . When the motor starts, the plate begins to emit an ultrasonic wave, the oscillation frequency of which is 1.7 MHz.
This causes the bristles to vibrate , making up to 100 million movements per minute. The wave begins to act directly on the surface of the tooth and surrounding tissues. Under its influence, plaque loses its connection with the surface of the crown and becomes mobile.
During further treatment of deposits, ultrasound destroys the membrane of each plaque cell, as a result of which it loosens and is easily removed from the tooth surface. The penetration depth of the wave during exposure is 4 mm.
Thanks to this property, it is able to penetrate not only dental tissue, but also periodontal tissue. Since most microbes accumulate under the gum, an ultrasonic brush will come in handy for removing them.
Deep penetration facilitates easy entry into the gum pocket and removal of soft and hard plaque . In addition, the wide action of ultrasonic vibrations allows for high-quality cleaning of all hard-to-reach places and areas: interdental spaces and the area of the last molars.
During the procedure, the device can transfer heat to the tissues , which helps absorb microelements contained in the toothpaste and restore gum trophism.
During thermal exposure, the regeneration process is activated, which is an important fact in the presence of wounds and ulcerations of the mucous membrane.
Principle of operation
The operation of sonic toothbrushes is based on the principle of mechanical action on tooth enamel.
Oscillatory movements, which cannot be achieved with a regular brush, are provided by the power unit to the bristles of the cleaning head.
As a result, in just one minute the working head makes from 7,000 to 40,000 vibrations .
Elimination of plaque and pathogenic bacteria occurs due to the independent movement of the bristles.
Therefore, there is no need to actively move the device during the cleaning process.
Keep in mind! Thanks to the high pulse frequency, the components of the toothpaste penetrate into hard-to-reach areas and deep layers of elements, having a beneficial effect on the condition of the oral cavity.
Advantages
The cost of brushes of this type has high limits. Therefore, before making a purchase, it is advisable to find out whether it is worth replacing your classic brush with this device. Those who used both options noted the following advantages of the ultrasonic brush:
- the ability to cleanse not only teeth, but also the mucous membranes of the oral cavity . An ultrasonic brush is often used for antibacterial cleansing of the tongue and inner surface of the cheeks;
- high antibacterial protection . Bacteria under the influence of waves are completely destroyed at the cellular level, even in the deep layers of the tissues of the oral cavity;
- When used correctly, the device can achieve noticeable lightening of the enamel . As a rule, after a month of regular use together with whitening paste or powder, the crowns lighten by 1-2 tones ;
- promotes the removal of tartar ;
- short cleaning period . Compared to a classic brush, the time needed to clean your teeth is halved. Exceeding this period may lead to increased sensitivity of the enamel;
- can penetrate into the most inaccessible places ;
- suitable for people with high enamel sensitivity ;
- copes well with cleaning elements of bracket systems;
- does not damage the enamel, improves the condition of the gums, stopping their bleeding and reducing swelling.
How to use for a child?
Dentists recommend letting your child use an electric toothbrush starting at the age of 2 years. When purchasing, choose a model with the recommended age indicated on the packaging.
First, you will need to clearly show the child by your own example how this is done . While brushing your child's teeth, you will need to hold his hand and guide its movements.
Small children should not undergo such a hygienic procedure on an ongoing basis. The fact is that the enamel layer of baby teeth is not hard enough, and it can be damaged if you are not careful enough.
And electric brushes act on the enamel more harshly than a conventional manual model. Therefore, it is reasonable to teach your child to use a manual brush, occasionally allowing him to clean with an electric device.
You can periodically use a children's electric brush up to the age of six. Then a complete transition to an electric version is possible.
Contraindications
A device of this type has an active effect on the tissues of the oral cavity , which can cause serious changes there and affect the functioning of some body systems.
Therefore, contraindications have been identified for the use of this device:
- prolonged bleeding gums;
- pathologies that provoke the leaching of minerals from dental tissue;
- the presence of outdated fillings, onlays, crowns. The vibration created by ultrasound can cause them to loosen or fall out;
- periodontal diseases in the acute stage;
- pulpitis, granuloma, open caries lesion;
- pregnancy period ;
- the presence of subcutaneous stimulators and other devices of a similar operating principle;
- mental pathologies that make independent use of the device impossible;
- malignant formation.
Of all the contraindications listed, only two are absolute - cancer and the presence of a stimulant. In other cases, contraindications can be considered relative.
The dentist can authorize the use during a personal meeting. If it is not possible to visit it, then before use it is necessary to consider the relationship between the benefits of such cleaning and possible negative consequences.

Experts' opinion
Most experts, after carefully studying the effects of brushing teeth with ultrasonic brushes, recommend them for daily use.
More and more dentists are of the opinion that the use of this device is necessary not only in adults, but also in childhood.
But only in this case should one take into account the risk of negative effects on the tissues of the oral cavity, as well as on crowns and onlays.
To reduce the risk of complications, doctors recommend using this type of brush no more than 2 times a day.
Selection rules
Before purchasing a sonic toothbrush, you need to not only familiarize yourself with the advantages and disadvantages of such a device.
Remember! It is important to decide in advance on the basic selection criteria, paying attention to the technical characteristics of the device.
- The number of vibrations - the more there are, the better the cleansing will be. In one minute, the bristles of a toothbrush can make from 7,000 to 40,000 brushing movements. This means that adults should choose a more powerful device.
- Type of food. Rechargeable devices are considered the most convenient, since to carry out several procedures it is enough to charge the device once without worrying about changing batteries.
- The degree of bristle hardness. The device should have medium-hard bristles, since bristles that are too hard can damage the enamel and gums.
- Manufacturer. It is worth giving preference to trusted manufacturers who guarantee the high quality of their products.
- Place of purchase. It is better to purchase the device at a pharmacy or specialized store, which will provide a warranty certificate for a long period.
- Price. Sound devices are quite expensive, however, their price does not always correspond to the quality. Experts say that you should choose a device in the mid-price category without overpaying for unnecessary functions.
A consultation with a dentist will also not be superfluous , because only a doctor can diagnose and recommend a device that is safe for teeth.
