The cleaning technology used by the toothbrush (see Type).

Nowadays, you can mainly find brushes with reciprocating-rotating, reciprocating-sweeping, and sonic cleaning technologies; the first two options can also be supplemented with pulsating technology. The main difference between these methods is the nature of the bristles' movement; here is a more detailed description of each option:

— Reciprocating-rotating. The traditional way of moving bristles in brushes with round heads. As the name suggests, such a head rotates back and forth at a small angle during operation. This technology is considered somewhat more advanced than reciprocating-sweeping — in particular, it provides better treatment of the interdental space and other similar places. True, such brushes are still not as effective as sonic ones — but they are also noticeably cheaper.

— Reciprocating-sweeping. Historically, this is the first technology used in brushes with oval attachments. The bristles in models with this operating principle oscillate left and right, like the twigs of a broom — hence the name. Classic reciprocating-sweeping brushes are simple in design, but not very effective. As a result, there are few such models these days, mostly budget devices, and most brushes with oval heads use more advanced sonic technology.

—...Pulsating. Usually this term refers to the operating format in which the bristles move up and down relative to the surface of the nozzle, in other words — they go deep into the head and extend back. This technology is almost never used in its pure form; it usually complements a reciprocating-rotating or reciprocating-sweeping head, providing the ability to 3D clean (see “Modes”). But if the 3D mode is not declared in the toothbrush, it is worth separately clarifying what is meant by pulsating technology. So, in some models we are actually talking about a whitening mode, when for maximum intensity of action the device does not work constantly, but in separate pulses; in others, the term “pulsating” actually refers to the sound mode of operation.

— Sonic. A cleaning technology that involves oscillating bristles with a small amplitude at a high frequency — up to 40 thousand oscillations per minute; this speed corresponds to the frequencies of audible sound, hence the name. This method of operation is considered more advanced than the reciprocating-rotating and especially the reciprocating-sweeping technology. Thus, due to the high speed of oscillations, sonic brushes create a fine homogeneous foam from paste, saliva and air during cleaning — this foam easily penetrates even hard-to-reach places; in addition, the vibration itself is effective in affecting plaque, including in the interdental space.

The number of working nozzles that are standardly supplied with the device. Nowadays, options are quite common with both one and two or three nozzles in the kit; and in the most extensive sets, this number can be four or five or even more.

In many sets, several nozzles may have different purposes. For instance, an irrigator, in addition to its standard nozzle, might include orthodontic and periodontal nozzles. However, it's important to note that models with the same number of accessories in the kit can have different specific specializations. So, when making a choice, it's wise to consider not just the quantity but also the types of nozzles available. Additionally, there's an option where several identical interchangeable heads come with one handle. This configuration is particularly common in toothbrushes. It enables multiple individuals, such as family members, to use a single device, and such a set is usually more cost-effective than purchasing individual toothbrushes for each person.

The number of power modes provided in the device. For flossing systems (see "Type"), this paragraph takes into account the characteristics of the irrigator; data on the toothbrush (if they differ) are indicated in the note.

It's important to distinguish between the number of power settings and the number of operating modes, as these are distinct parameters. Refer to the "Operating modes" section for details on the various modes. In this context, we emphasize that power adjustment, if available, may not be accessible in all modes. For example, in an irrigator offering two modes of operation—continuous jet and pulsation—power adjustment might only be available in the continuous jet mode.

Having multiple power settings enhances the versatility of the device. Even if a device technically offers only one operating mode, the ability to adjust the intensity of the treatment allows users to tailor the device for various tasks. For instance, in many toothbrushes, the traditional 2D brushing mode at its lowest power setting effectively serves as a gentle treatment option. However, it's worth noting that the capability to adjust power levels can somewhat increase the device's cost.

Modes of operation supported by the device.

Toothbrushes nowadays offer a wide range of modes beyond the traditional daily cleaning (often referred to as "2D" mode). You can find toothbrushes with options like the advanced 3D mode, as well as programs for gentle and deep cleaning, polishing, whitening, gum massage and tongue cleaning. On the other hand, irrigators typically offer different modes in addition to the standard continuous water jet. These additional modes often include pulsation and spray options.

Here is a detailed description of the most popular options found in brushes:

— Daily cleaning (2D). The "2D" mode of operation in toothbrushes closely resembles the traditional manual toothbrush experience. In this mode, the bristles of the brush move in a single plane, and the exact movement pattern may vary depending on the cleaning technology used. The intensity of brushing is typically medium to high, making it suitable for individuals with relatively healthy and not overly sensitive teeth. The recommended daily brushing time is 2 minutes, with 30 seconds allocated to each quadrant of the mouth. These corresponding settings are usually available in the timer function, if the toothbrush is equipped...with one. While "2D" brushing is somewhat less effective than "3D" (as mentioned below), it's a feature that can even be found in more affordable toothbrush models.

— Daily cleaning (3D). This feature, available in brushes with reciprocating-rotating and reciprocating-sweeping technology, involves bristle pulsation in addition to the standard cleaning motion. The pulsating movement, which goes deep into the brush head and back, enables cleaning in three dimensions simultaneously. This greatly enhances efficiency compared to the 2D cleaning mentioned earlier. These bristles not only address the outer tooth surfaces but also reach the sides and interdental spaces to some extent (though it's not a complete replacement for dental floss). However, it's worth noting that this advanced functionality typically comes at a higher cost.

— Gentle cleaning. The gentle treatment program, typically used for sensitive teeth and gums prone to bleeding, is common in brushes with reciprocating-rotating and reciprocating-brushing technologies. In these brushes, the gentle mode often involves reducing the nozzle's rotation or vibration speed. In sonic and ultrasonic models, gentler treatment is achieved by reducing vibration intensity. Regardless of the technology, this mode aims to minimize discomfort during brushing and the risk of gum damage, even when using standard nozzles. For the gentlest effect, it's advisable to use this function with a nozzle designed for sensitive teeth.

— Deep cleaning. Most often, this name means cleaning with a standard intensity, but an increased duration — for example, 3 minutes instead of the usual 2 minutes (45 seconds for each quadrant of the mouth instead of the traditional 30 seconds). This mode allows you to effectively clean your teeth and remove dirt, for which normal daily brushing is not enough.

— Polishing. A mode for treating relatively clean teeth that do not require a full-length cleaning. Usually, polishing is carried out at a reduced frequency of vibrations (rotations) and takes noticeably less time than conventional processing (for example, 1 minute instead of the traditional 2 minutes).

— Whitening. A special mode for whitening tooth enamel and removing stains, especially from the front teeth, is often an extended version of the regular brushing mode. For example, in a whitening mode, the brush might operate normally for 2 minutes and then switch to increased intensity for 30 seconds. Specific details about this mode, including any contraindications (especially for individuals with sensitive teeth or gum issues), should be checked separately.

— Massage gums. Gum treatment can be offered either as a separate program or as an add-on to the regular brushing routine. In the latter case, it typically involves a standard 2-minute toothbrushing program followed by activating an additional mode. This function not only ensures effective cleaning but also contributes to gum strengthening. It can be beneficial for addressing issues like inflammation and bleeding gums, although consulting a dentist is advisable in such cases.

— Cleaning the tongue. A separate mode for tongue cleaning is available in many electric toothbrushes. Brushing the tongue with an electric toothbrush can often cause discomfort due to tickling, so this mode typically offers a brief cleaning session lasting about 20 seconds. If needed, you can perform multiple sessions. It's important to note that the presence of a tongue cleaning mode doesn't necessarily mean that a specialized nozzle for tongue cleaning is included in the kit (as discussed in the "Nozzles" section), although it's commonly included.

It should be noted that in some toothbrushes, the mode change is carried out due to “smart” nozzles: when such a nozzle is installed, the device recognizes it by the built-in chip and automatically switches to the appropriate programme.

In turn, in irrigators, the features of the main modes are as follows:

— Jet (monoflow). The classic, most popular working format: a constant jet with a constant pressure. Provides sufficient efficiency for most tasks for which irrigators are used, while being extremely simple to implement and can be provided even in the most inexpensive models.

— Pulsating. Water supply with variable pressure. This mode is especially effective for removing dirt from the interdental space, under braces and in other hard-to-reach places.

— Spray. In this mode, a mixture of water and air is fed through the nozzle, due to which, instead of the usual jet, a cloud of small droplets flying at high speed is obtained at the exit. This mode is great for massaging the gums and general cleaning of the mouth.

The frequency of sound vibrations provided by a brush with a sonic or ultrasonic principle of operation (see "Cleaning technology").

A high oscillation frequency (from 40 000/min and above), ositively impacts the efficiency and quality of oral processing. In fact, brushes that generate more than 40,000 oscillations per minute are often referred to as ultrasonic brushes, although true ultrasound starts at much higher frequencies. However, it's important to note that these high-speed brushes tend to come with a higher price tag. It's also worth mentioning that for specific tasks, such as delicate treatment of sensitive teeth, relatively lower frequencies may be more suitable. Therefore, when choosing an oral care device, it's essential not to prioritize the maximum oscillation frequency but rather consider the individual needs of the user(s). Consulting a dentist for personalized recommendations is a prudent approach.

It's important to clarify that in this context, a full cycle of bristle movement is defined as one complete oscillation, which includes both the forward and backward motion. Some manufacturers employ a marketing tactic where they list their brush's operating frequency not in terms of complete oscillations but as the number of movements per minute, counting only half of the cycle — either the forward or backward motion. This can lead to impressive-sounding numbers in product specifications since the count of...movements is double the count of oscillations. However, the primary performance metric remains the number of complete cycles or oscillations, and that's the value provided in this section of our catalog.

The pressure of the water supplied by the irrigator (see "Type") to the operating nozzle. Usually, this pressure can be adjusted within a certain range, since different situations and purposes require different processing intensity. The wider this range, the more versatile the device.

The lower limit of the pressure range in modern irrigators is around 30 kPa; similar values are set for procedures for sensitive teeth, for certain gum diseases and in other cases where the most gentle treatment is required. 400 – 500 kPa is considered an average level, and 600 – 650 kPa is considered high, such indicators allow for deep cleaning (see "Functions"). And higher values are rare, and they are used mainly when cleaning the tongue. However, it is best to consult with a dentist before purchasing an irrigator and choose a model for working pressure based on the recommendations received.

The volume of the reservoir for water (or treatment solution) provided in the design of the irrigator or flossing system (see "Type").

In general, the larger the tank, the less often you have to refill the device, but the larger, heavier and more expensive the whole structure is. Thus, in portable format irrigators, where the water tank is built right into the handle, the capacity is small — even in the largest models it usually does not exceed 400 ml, a larger tank would noticeably complicate use. However, even the smallest volumes in such cases are usually enough for at least one standard procedure. But stationary models, consisting of a handle and a separate main unit, can hold very significant volumes of water — up to 1.5 L or even more.

The presence of a timer in the design of the device. All types of dental hygiene appliances can be equipped with this function (see "Type").

The timer function counts down and provides alerts, often at specific intervals, to help users monitor the time spent on brushing their teeth and mouth. This ensures that the oral care routine is effective without unnecessary prolongation. The timer settings can vary depending on the selected brushing program (as discussed in the "Modes" section). Following the standard recommendations of dentists, a typical daily brushing session should last at least 2 minutes, with 30 seconds allocated for each quadrant of the teeth. Consequently, when using this mode, the timer typically counts down from 2 minutes and signals every 30 seconds to prompt the user to move the brush to another section of the mouth.

The timer function can vary in its operation, depending on the specific model of the toothbrush or irrigator. The simplest approach involves fixed time settings for each mode, accompanied by audible and/or visual signals. Models equipped with smartphone synchronization (as discussed in the "Synchronization with a smartphone" section) often display timer data on the smartphone screen and allow users to customize the countdown duration to their preferences. In some children's brushes (as mentioned earlier), a musical timer is used, where the countdown continues until a melody finishes playin...g. There are also other unique features related to this function. Regardless of the specific implementation, the timer simplifies the use of the toothbrush or irrigator, eliminating the need for users to manually track the time themselves.

The presence of a pressure sensor in the device — a sensor that monitors the force with which the working nozzle is pressed against the teeth/gums.

This feature is primarily found in toothbrushes, including those that are part of flossing system units (as discussed in the "Type" section), but it can also be included in irrigators. Its primary function is to prevent potential harm to the teeth and gums caused by excessive pressure during brushing. The sensor's response can vary from one device to another; some devices emit a warning signal, while others reduce the bristle movement speed, and some may even shut off entirely in response to excessive pressure.

Having a pressure sensor in such devices can be beneficial not only for individuals with healthy teeth but also for those with heightened sensitivity or gum issues. It's a highly desirable feature for maintaining oral health. However, it's important to note that in many models, the pressure sensor is not integrated into the main body of the device but is instead part of the replaceable nozzle. Additionally, not all complete nozzle options may have this function, so it's essential to verify these details separately when choosing a device.
