Number of nozzles
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.
Model of the replacement head
Models of replacement heads supplied with the device.
This information is valuable for assessing the capabilities of a specific model and for sourcing additional, spare, or replacement nozzles, particularly for toothbrushes and dental centers that naturally use such devices (as indicated in "Type"). Firstly, it's advisable to replace the heads in these devices every 3-6 months, similar to regular toothbrushes. Secondly, if each user purchases their own nozzle while sharing a single handle, it's a cost-effective alternative to buying a separate brush for each individual, although it may be less convenient. Regardless, knowing the model of the interchangeable nozzle will save you time and effort when searching for compatible accessories.
Frequency of movements / pulsations
The frequency of sound vibrations provided by a toothbrush with a sonic operating principle. This parameter also means the maximum pulsation frequency for toothbrushes with support for pulsating cleaning technology (see above) and for irrigators with a pulsed operating mode. For dental centers (see "Type"), data on the irrigator is usually specified here, and the pulsation frequency of the toothbrush (if this parameter is relevant for it) is indicated in a separate note
High frequency of movements and
pulsations(from 40 thousand/min and higher) has a positive effect on the efficiency and quality of treatment, allowing you to quickly deal with dense plaque and even tartar. On the other hand, too intensive treatment can also be undesirable - for example, with high tooth sensitivity. All this is also relevant for irrigators - except that the operating frequencies in them are noticeably lower, such devices very rarely produce more than 2 thousand pulsations per minute. So when choosing, do not chase the maximum indicators of the frequency of movements and pulsations, but first of all it is important to take into account the individual characteristics of the user - for a full guarantee, it would not hurt to consult a dentist about this.
Smartphone synchronization
The ability
to synchronize the device with a smartphone, tablet or other similar gadget. It is found mainly in toothbrushes, but can also be used in other types of devices (see "Type").
Synchronization with an external gadget, typically via Bluetooth, requires the installation of a dedicated application. The functionality of this app determines the available features when using the toothbrush with a smartphone or tablet. However, these functions extend well beyond what the toothbrush can do on its own, thanks to the smartphone or tablet's screen capabilities. Common features include displaying a timer countdown and the ability to customize the timer settings if the default values don't meet the user's preferences. The application also typically provides other relevant information, such as the selected brushing program and battery charge status. Some toothbrushes with this feature can even assess the overall effectiveness of each brushing session, process this data within the app (like tracking trends over time), and sometimes transmit this information over the internet, allowing for remote consultations with a dentist.
While in the past, the primary drawback of models offering smartphone synchronization was their high price, nowadays, even low-cost-friendly toothbrushes come with this feature. Additionally, some models go the extra mile by including dedicated smartphone holders for added convenience.
Max. operating time
This refers to the maximum duration a device can run continuously when powered by a fully charged battery or fresh batteries. It's worth noting that this metric may also apply to models designed for mains power, such as flossing systems that include rechargeable toothbrushes, in which case we're referring to the battery life of these toothbrushes.
It's important to note that device specifications typically indicate the maximum runtime under ideal conditions, often in the most energy-efficient mode of operation (and for models with replaceable batteries, using high-quality batteries). The actual battery life can vary depending on specific usage conditions. However, this parameter still serves as a valuable basis for comparing different models. Generally, differences in the claimed operating time correspond proportionally to the real differences in battery life. For example, if one toothbrush has a stated operating time of 20 minutes and another boasts 40 minutes, in practice, their battery life (under similar conditions) will likely differ by approximately two times.
It's important to consider that, for toothbrushes, this parameter can help estimate the number of brushing sessions you can expect on a single charge. Typically, the recommended daily brushing duration is 2 minutes. So, if a toothbrush has an operating time of 30 minutes, it's sufficient for approximately 15 cleaning sessions (or more realistically, around 14 or 13).
USB charging
The ability to charge the battery in the device from a standard USB port.
Refer to the "Type of power" section for battery details.
Charging via USB offers several advantages over traditional mains charging. The primary benefit is the widespread availability of USB ports in computers, laptops, tablets, and various electronic devices. USB connectors are standard outputs in portable power banks, and USB adapters can convert 230V socket and car cigarette lighter socket outputs. This power source allows you to charge your toothbrush or irrigator not only from mains power but also from various other sources, even when sockets are unavailable, such as from a laptop or a power bank. This is particularly convenient during travel.
Another notable aspect of this charging method is that it often eliminates the need for a dedicated charger. All you need is a basic cable to connect the toothbrush or irrigator to a USB port. Typically, such a cable is included with the device, and the device itself features a standard microUSB port for power connection. This flexibility allows you to use alternative cables if needed, which are compatible with the plug type, making it more convenient and adaptable.
However, it's important to mention that these standard sockets on the device are not well-suited for use with charging stands, as discussed in the "Additionally in the kit" section. Consequently, some toothbrushes and irrigators
...that use USB charging may not include charging stands at all, while others employ a unique design. In these cases, a dedicated socket for the charging stand is integrated into the device, and USB charging becomes accessible when the device is placed within a travel case, which also serves as a transitional component.
