(1) Hold the brush handle, place the brush head on the neck of the tooth, with the bristles at an angle of 45° to the long axis of the tooth, pointing the bristles in the direction of the root (maxillary teeth up, mandibular teeth down), and apply slight pressure so that the bristles partially enter the gingival sulcus and partially reach the gingival margin. Be careful to use a toothbrush with softer bristles. (2) In a group of 2-3 teeth, shake the toothbrush horizontally at a short distance (about 2mm) about 10 times, then turn the toothbrush toward the crown and brush the labial and lingual (palatal) surfaces. Be careful to move gently. (3) Move the toothbrush to the position of the next group of 2-3 teeth and reposition it, taking care that the placement should overlap the position of 1-2 teeth. (4) When brushing the lingual (palatal) surface of the upper anterior teeth, place the brush head vertically on the tooth surface so that the anterior bristles touch the gingival margin or enter the gingival sulcus and do an up-and-down pulling tremor, brushing from top to bottom, without brushing back and forth. When brushing the lingual surface of the lower front teeth, brush from the bottom up. 2.Brush the buccolingual (palatal) surface with the brush method, and brush each part of the labial and lingual (palatal) surfaces of the maxillary and mandibular dental arches in order, without missing. 3. Brush the occlusal surface with the brush handle in hand, point the bristles to the occlusal surface and brush back and forth with slight force, paying attention to the upper and lower left and right segments must be brushed. In order to ensure that each tooth surface has enough brushing time, brush for not less than five minutes each time. In order to control plaque and maintain oral hygiene and fresh breath, brush your teeth at least once a day in the morning and evening, and even better if you make a habit of brushing your teeth after lunch.
