Comparison Seago E2 vs Seago SG-507

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 brush modes provided by the device. The presence of several modes allows using the device for different procedures (for example, daily cleaning, delicate cleaning, whitening, etc.). Each such program has its own features of the working nozzle, as well as its own timer settings. The downside of such multifunctionality is the increased cost. In any case, this feature significantly expands the capabilities of the device; however, the specific set of modes may be different - it would not hurt to clarify it separately.

In this case, the mode means the general format of operation. For more information on the different formats, see "Modes" below. Note that this parameter should not be confused with the number of power settings. The latter is specified separately - see "Power modes", and in general, these characteristics are practically independent of each other. For example, a brush with one mode of operation can have several power settings. And vice versa, there may be only one power level, but several formats of operation.

Operating modes supported by the device.

Nowadays, toothbrushes offer the greatest variety of modes. In addition to traditional (so-called '2D') daily cleaning, they may include a 3D-mode, programs for sensitive and deep cleaning, polishing, whitening, gum massage, and tongue cleaning.

— Daily Cleaning (2D). The operating mode most similar to traditional (manual) toothbrushes. In this mode, the bristles move in a single plane; the trajectory can vary depending on the cleaning technology (see below). The intensity is usually medium/high, making this mode primarily for relatively healthy and not too sensitive teeth. The recommended time for daily cleaning is 2 minutes, 30 seconds for each quadrant of the mouth; relevant settings are typically provided in the timer (if available — see below). Generally, 2D cleaning is somewhat less effective than 3D (see below), but even the cheapest toothbrushes can offer this feature.

— Daily Cleaning (3D). A feature found in brushes with oscillating-rotating and sweeping technology. In these models, in addition to the primary cleaning technology, there is an up-and-down pulsation of bristles (more precisely, into the head and back). This allows cleaning in three planes, consid...erably improving efficiency compared to the 2D cleaning described above: the bristles not only process the outer tooth surface but also somewhat reach the sides and interdental spaces (although it is not a full replacement for using dental floss). The traditional downside of this feature is the relatively high cost.

— Sensitive Cleaning. A program for gentle treatment, mainly used for sensitive teeth and gums prone to bleeding. In brushes with oscillating-rotating and sweeping cleaning technology (see below), the sensitive mode usually involves reduced rotation/oscillation speed of the nozzle; in sonic and ultrasonic models, gentle treatment may be provided by decreasing the amplitude of oscillations. In any case, this mode minimizes discomfort during cleaning and the risk of gum damage — even with standard nozzles; for the most gentle effect, use this function with a sensitive teeth nozzle.

— Deep Cleaning. This name commonly refers to a cleaning with standard intensity, but extended duration — for instance, 3 minutes instead of the usual 2 minutes (45 seconds per quadrant of the mouth instead of the traditional 30 seconds). This mode allows for maximum effective tooth cleaning and removal of deposits insufficiently cleared by regular daily cleaning.

— Polishing. A mode for treating relatively clean teeth that do not require a full cleaning session. Usually, polishing is performed at a reduced frequency of oscillations (rotations) and takes significantly less time than regular treatment (e.g., 1 minute instead of the traditional 2 minutes).

— Whitening. A special mode for lightening tooth enamel and removing various stains, especially from the front teeth. It may be an extended version of the usual cleaning mode: for example, when whitening is enabled, the brush operates in a regular format for 2 minutes, then at increased intensity for 30 seconds. It's worth checking these specifics separately; also check contraindications for using this mode (especially for sensitive teeth and/or gum issues).

— Gum Massage. Gum treatment may be provided as a completely separate program or as an addition to the normal cleaning mode. This feature not only ensures effective cleaning but also strengthens the gums — useful for treating inflammation and bleeding, though it's best to consult with a doctor beforehand in such cases.

— Tongue Cleaning. A separate mode for cleaning the tongue. For many people, cleaning the tongue with an electric toothbrush causes a tickling sensation that's hard to endure for a long time. Therefore, this mode typically involves a brief duration of continuous treatment — around 20 seconds; several such 'sessions' can be made if necessary. It's also worth noting that having a tongue cleaning mode does not automatically mean a special attachment for such cleaning is included (see 'Attachments'), although such a tool is usually part of the set.

Note that in some toothbrushes, changing modes is done using 'smart' attachments: when such an attachment is installed, the device recognizes it via a built-in chip and automatically switches to the appropriate program.

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 power type used by the device.

Nowadays, battery power is the most popular — it is provided in most toothbrushes. Power from batteries is noticeably less common. Here is a more detailed description of each type of power:

— Battery. Powered by its own built-in battery, often non-removable. This energy source allows the device to operate independently of wall outlets — or more precisely, outlets are only needed for periodic recharging of the battery. Compared to the other type of alternative power — batteries (see below) — batteries have several advantages. Firstly, they are more compact, lighter, and yet have a higher capacity, providing longer operation on a charge. Secondly, a battery comes with the device, avoiding the need to spend time and money on purchasing separate power sources; and some models are even partially charged and can be used straight "from the box." Thirdly, the costs of operating battery-powered devices are minimal: when the charge is depleted, you just need to recharge the battery, instead of replacing it. True, this requires a power source and some time; and unlike batteries, a depleted battery can't be quickly replaced with a fresh one. However, in the case of toothbrushes and irrigators, this is usually not critical: such devices are typically placed on a charging stand after each use, which can be connected to a regular outlet, and the charging time is short. Battery-powered models are somewhat more expensive than their batt...ery-operated counterparts, but this price difference is justified by the differences in package contents and is often quickly recouped.

— Batteries. Powered by replaceable standard-sized elements — for example, "AA" batteries. Devices with this type of power are noticeably cheaper than battery-powered ones — mainly because the energy source is usually not included and must be purchased separately. On one hand, this incurs additional costs, but on the other hand, it allows the choice of a power element at one’s discretion. In the sizes used in toothbrushes, both disposable batteries and rechargeable batteries can be found. This gives users the choice: regularly purchasing relatively inexpensive batteries, or investing once in a battery with a charger. The clear advantage of replaceable elements over built-in batteries is the ability for a quick swap. This minimizes downtime due to recharging, or even allows operation without wall outlets — as long as there’s a stock of batteries that’s kept replenished. At the same time, such capabilities aren’t often genuinely necessary; and replaceable batteries, despite similar sizes, generally fall noticeably short of built-in batteries in terms of capacity and require more frequent replacements or recharging. Thus, this type of power is mainly characteristic of inexpensive toothbrushes nowadays, where it is used also to reduce the cost.

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.

An indicator showing the battery charge level.

This function is predominantly found in battery-powered devices (as mentioned in the "Type of power" section). Implementing a charge indicator with replaceable batteries is challenging but occasionally seen. The specifics of this feature and how it operates can vary. The simplest form of a charge indicator is composed of LEDs. For instance, a green light might indicate a normal charge level, yellow signals a low charge, red signifies the need for charging, and blinking typically indicates that charging is in progress. More advanced indicators exist as well, such as those with their own displays that can show the specific charge level using a battery icon or even as a percentage. Regardless of the design, this feature simplifies monitoring battery status and reduces the risk of finding yourself with a dead battery at an inconvenient time.

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.

General dimensions of the device. Most manufacturers report this data only for stationary devices — irrigators of the appropriate variety and dental centers (see "Type") — because it is believed that toothbrushes (even with stands) are not so large as to be inconvenient, and not so varied in size, to pay attention to this difference.

Note that the dimensions are usually given only for the main unit, without taking into account the tools installed on it; however, the size of these instruments, again, it is not large enough to cause serious inconvenience.
