What is Sonicare sonic toothbrush? Brush your teeth with sound waves?

40% of the teeth are located between the teeth and below the gum line, so manual toothbrushes can't be cleaned, which leads to various oral problems. Sonic vibration toothbrush will drive the bristles of the toothbrush to swing up and down when brushing teeth, with a swing frequency of more than 30,000 times per minute. Combined with the swing amplitude of 5.5 mm, it will drive the oral liquid to flow quickly and produce flowing cleaning force, thus effectively cleaning teeth and gaps. There will be a lot of toothpaste foam and water flowing out when using, so that some bacteria, tartar and so on in the mouth can be brushed clean. Sonicare of Philips is a very good oral care brand.
