The different types of electric toothbrush

The best electric toothbrush depends on your preferences and budget. Certain physical and health conditions can also influence the type of toothbrush you will choose, so if you are unsure of the type, you can consult and ask your doctor or dentist.

  • Rotary toothbrush (2D)

This type of electric toothbrush consists of one or more brush heads that rotate around their axis. It is practically a basic model, the commercial availability of which is only limited today. A certain level of manual capacity is required for this brush.

  • Rotary / pulsating toothbrush (3D)

Also known as an oscillating-rotating toothbrush, this type of construction is still today the model par excellence among electric toothbrushes. The focal point is the arrangement of the toothbrush, whose movements alternate from left to right. The brush head is rounded and applied at high frequency to the teeth. These brushes are capable of removing a large amount of dental plaque, but they require some skill. Like hand toothbrushes, they should be used with care depending on the structure of the teeth and their condition. Everything is done by pressure, which in reverse function also effectively removes the resistant plate.

These models are already available at a low price, but they still offer good cleaning. Follow-up costs are very likely as regular replacement of the brush heads will be required. The above risks from improper cleaning techniques can be minimized through exercise and the dentist's instructions.

  • Sonic toothbrushes

Toothbrushes sonic existed since the early 90s, we have already described above as toothbrushes "piezoelectric". The vibrations are generated around the bristles through the use of sound technology, which varies from 30,000 to 40,000 movements per minute (pulses). As a result, the bristles "float" on the teeth and gum, exerting no pressure. This results in a normal cleaning process, which also effectively cleans the interdental spaces. Such models are particularly effective because of the significantly lower risk of abrasion of enamel or dentin.

This cleaning technique is particularly important because only low pressure is applied to the gum. This prevents chronic gum injury and also reduces the risk of gum recession. A growing number of older people suffer from it, which causes not only cosmetic problems but also factors that affect the periodontium.

  • Ultrasonic toothbrush

The ultrasonic toothbrush represents an indication of the toothbrush described above. The sound frequency is at least 20,000 hertz, which corresponds to 2.4 million vibrations per minute. There are even models with significantly higher performance indicators up to 1.6 MHz, which corresponds to 192 million vibrations per minute. Piezo-ceramic oscillators are generally used for this purpose. These models generally offer an adjustment to "classic" sound components and sound frequencies.

They sell for much more than normal commercial toothbrushes, although there is no scientific indication of "improved cleaning performance". In addition, many users find the operating sound very annoying.
