The difference between a manual toothbrush and an electric toothbrush:
1: When brushing your teeth manually, you can only brush your teeth because you can't completely see the mouth. Therefore, you can't ensure that every part and gap of the tooth is brushed. Brushing your teeth with electric toothbrush, the flow cleansing force generated by sonic technology and wider contact. The face can be more comprehensively taken care of every tooth surface and deep in the teeth to effectively remove plaque.

2: When you brush your teeth, you are not light and heavy, and your teeth are red and swollen? When brushing your teeth manually, it is often difficult to control the force, or to make it more powerful for brushing, which in turn hurts the teeth; with an electric toothbrush, the uniform force cleans the teeth without causing damage.

3: How much is the right time for brushing? When you brush your teeth manually, you will even walk away. You don’t know how long the brush is brushed. The smart timer function of the electric toothbrush ensures that the brushing time is controlled in a reasonable 2 minutes, 30 seconds segmentation reminder to ensure each area. Brush your teeth evenly.

4: In addition to teeth, the health of the gums is also very important. Compared with manual brushing, it often hurts the gums. Electric toothbrushes often have different modes, such as sensitive patterns for the gums, massage mode and health care mode, to avoid periodontitis, and to ensure the health of the mouth more comprehensively.
