Comparison of 3 Types of Electric Toothbrush

Vibration, sonic or ultrasonic? Rotating or oscillating?
Electric toothbrush can be divided into three different technologies, which also differ in application, brush head shape and brush head movement.

1. Rotary toothbrush
2. Sonic toothbrush
3. Ultrasonic toothbrush

Rotary toothbrush

When we think of an electric toothbrush, we usually think of the rotary toothbrush. It is the classic electric toothbrush and was the first to hit the market. The acquisition costs are comparably low and they achieve a very good result when removing plaque and other deposits.

Unlike a sonic toothbrush, the rotary toothbrush is driven by an electric motor that imitates the circular cleaning movements of a manual toothbrush. The brush heads are always round, so that you can also tell which technology is involved.
The round brush head swings back and forth in a semicircle with 4,000 to 8,800 movements per minute tomorrow, so that all teeth are completely covered. With some models, the brush head movements are supplemented by additional impulses or vibrations (up to 40,000 per minute), which achieves an even more thorough result.
Since the round brush heads are relatively small, they can also be used to clean the back molars, which are often neglected with a manual toothbrush. The brush heads are also available in different designs. They differ, for example, in the length of the bristles, the arrangement of the bristles and the degree of hardness of the bristles.
