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.
Auto frequency control
The presence
of an automatic frequency control in a toothbrush (sold separately or included in the delivery of the dental centre — see "Type").
This feature is exclusively present in sonic and ultrasonic toothbrush models, as mentioned in the "Cleaning Technology" section. The fundamental idea behind it is that the toothbrush automatically adjusts its oscillation frequency based on the selected mode. However, the specific implementation can vary. Some models operate only at predetermined frequency settings, while others offer manual adjustment of this parameter. There are also different control methods, such as the use of "smart" nozzles that trigger the corresponding mode automatically when attached. Regardless of the approach, automatic frequency control simplifies the user's experience by eliminating the need for unnecessary adjustments.
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).
Full charge time
The time required to charge the battery from zero to 100% in a device with the appropriate power type (see above). This parameter can vary from 1 – 3 hours in relatively simple and low-power devices to a day in advanced models with capacious batteries. At the same time, the longer
the maximum operating time on a charge (see above), the longer, usually, the time required for charging, although there is no hard dependence here.
In general,
having fast charging capabilities improves the convenience of a device by reducing interruptions in its operation. However, there is a trade-off to consider: fast charging often means either a smaller battery capacity or a higher price due to the use of specialized technologies to speed up the charging process. When evaluating this parameter, it's essential to think about how you intend to use the device. For instance, if a toothbrush or irrigator is solely used at home by one person and comes with a charging stand, fast charging may not be a critical factor. The device remains consistently charged as it's constantly on the charger, and its battery doesn't deplete significantly during one use. The time between sessions, usually around 8 to 12 hours, is more than enough to maintain a charged battery, even for devices with slower charging. However, if you plan to use the device while traveling, where access to power outlets is sporadic, it's preferable to have minima
...l charging time to ensure you can recharge quickly during your trips.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.Weight
The total weight of the device is an important consideration. In the case of stationary irrigators and dental centers (as mentioned in the "Type" section), weight isn't a significant factor since the main unit is placed on a stand or wall, and you don't have to hold it. In fact, for some of these models, weight may not even be specified. However, when it comes to toothbrushes or portable irrigators, the device's weight becomes a crucial factor. A heavy device can strain your hand and make it challenging to use during teeth brushing or other procedures. It's generally recommended that the weight of a portable device should not exceed 200 g, and lighter is often better. It's worth noting that in models that come with stands (as discussed earlier), the total weight is typically provided, accounting for both the main unit and the stand. The weight of the main unit alone is usually around 1.5 to 2 times less than the total weight.
