The difference between electric toothbrush and ordinary toothbrush

The main difference between ordinary toothbrush and electric toothbrush is that ordinary toothbrush needs manpower to control its strength, time, size and direction, while the strength of electric toothbrush is controlled by motor, so the strength is relatively balanced.

The cleaning of ordinary toothbrushes is to gradually remove large pieces of food residue left on the surface of teeth through repeated gentle exertion with both hands. Electric toothbrushes can be divided into two categories: rotary electric toothbrushes and acoustic electric toothbrushes. Rotary electric toothbrush relies on the mechanical friction of high-speed rotation of the brush head to clean teeth; The acoustic vibration electric toothbrush makes the brush head vibrate at high frequency through the ultrasonic transducer in the brush head, thus loosening the dental plaque and tartar on the tooth surface until it is removed.

Selection requirements of electric toothbrush

1, there must be multiple modes to choose from.

2. It is recommended to choose a soft brush head. There is no obvious difference in the efficacy of electric toothbrushes with different hardness in removing dental plaque, and the soft brush head has less wear on the enamel surface.

3. Among the electric toothbrushes, sonic electric toothbrushes are more recommended, and it is best to choose sonic toothbrushes with stable brush head swing.

It is worth noting that if the electric toothbrush cannot be used correctly, long-term use will cause tooth wear and sensitivity, especially the neck. So be sure to use the electric toothbrush correctly according to the instructions and the dentist's instructions.
