Background technique

Brushing teeth is the easiest way of oral health care, but a considerable number of people lack scientific guidance. At present, the most effective brushing method recognized by the stomatology community is the modified Pasteur brushing method, that is, the horizontal flutter brushing method. This method requires that when holding the toothbrush, the bristles are at an angle of 45° with the long axis of the tooth, pointing to the gingival-dental junction, and brushing horizontally with flutter. However, more than 90% of people use the wrong brushing method (such as horizontal brushing), which can lead to gum damage (such as gum bleeding, recession) and low cleaning efficiency, affecting users' perception and judgment of the effect of brushing, thereby underestimating brushing. health utility. Secondly, the traditional toothbrush design, whether it is a manual type or an electric type, requires the user to adjust the angle and direction of the brush head to clean the jaw, buccal and occlusal surfaces of the teeth. This operation has certain technical requirements. , especially when cleaning the sides of the upper and lower jaws, may stimulate the gag reflex, leading to vomiting. In addition, smoking, drinking tea, etc. will cause the accumulation of pigments in the front teeth. If there is no timely and effective cleaning, it will inevitably lead to the double loss of the aesthetics and functional damage of the teeth. Therefore, there is a need for a surround-type sonic toothbrush that is easy to operate, convenient and practical, and surrounds and surrounds the jaw side, buccal side and occlusal surface of the teeth for cleaning, so as to solve people's oral problems.
