When brushing teeth with Pasteur brushing method, the brush head needs to be placed on the neck of the tooth, the bristles and the long axis of the tooth form a 45° angle, and the bristles point to the root of the tooth. Let the bristles partly enter the gingival sulcus and partly reach the gingival margin. Take 2-3 teeth as a group, vibrate the toothbrush 4-6 times at a short distance of about 2 mm, and then move the toothbrush to the next group of 2-3 teeth. The position of the teeth is repositioned and the toothbrush is vibrated horizontally 4 to 6 times to clean the teeth in turn.
