Brushing is a self oral health care measure that we carry out every day, and it has a close relationship with the health of the dental body and periodontal tissues,. Brushing can remove plaque and soft tartar on the surface of the teeth, preventing dental caries, and with the help of toothbrush massage to increase the blood circulation of the gum tissue and the degree of keratinization of epithelial tissues, which helps to enhance the health of the periodontal tissues. However, incorrect brushing method, not only can not achieve the purpose of cleaning teeth, but also can cause gum recession, increase the occurrence of dental caries, alveolar bone resorption or the chance of wedge-shaped defects. Although each person every day in the brush, also know the importance of brushing, but you know the correct and effective method of brushing? Many people are accustomed to brushing teeth with sawing horizontal brush method, not only can not remove the food debris in the gap, but also damage the neck of the teeth, over time the formation of deep grooves in the neck of the teeth, dentin sensitivity and even pulpitis, periapical periodontitis and so on. Such brushing method should be firmly abandoned! Effective and correct brushing methods are the vertical brush method and the horizontal flutter method. Vertical brushing is a simple and easy method, that is, the upper teeth from the top to the bottom of the brush, the lower teeth from the bottom to the top of the brush, the occlusal surface back and forth brush, suitable for children, lip misalignment of the teeth (especially cuspids and premolars), tilted teeth, exposed root surfaces, overlap of the teeth, and so on. Horizontal vibratory brushing method is recommended by dentists to effectively remove plaque from the neck of the teeth and the gingival sulcus, which is the most effective way to control gums and periodontal infections. The main points of brushing are as follows: (1) hold the brush handle, the bristles point to the direction of the root tip (maxillary teeth upward, mandibular teeth downward), first parallel to the long axis of the teeth, and then slightly rotated, and the gingival margin at an angle of 45°. (2) Angle of bristles: Place the bristles of the toothbrush in a position pointing straight to the gingival sulcus, with the bristles at an angle of about 45° to the long axis of the tooth. (3) Light pressure: Do not flex the bristles. Apply light pressure so that the bristle end enters the gingival sulcus. (4) Fluttering the toothbrush: Brush at short distances; flutter the toothbrush back and forth, do not let the bristle end leave the gingival sulcus, flutter at least 10 times. (5) Repositioning the toothbrush: Move the toothbrush to the next set of 2 to 3 teeth, taking care to overlap. (6) Repeat brushing: Repeat brushing on each part of the labial and lingual surfaces of the maxillary and mandibular dental arches. (7) Brush the lingual and palatal surfaces of the front teeth, place the toothbrush vertically on the lingual and palatal surfaces of the front teeth, so that the bristles are perpendicular and point towards and into the gingival sulcus. In short, brushing is the most basic means of personal oral health care, if you can do effective and correct brushing, caries periodontal disease and other common oral diseases can play a good preventive role. It should be emphasized that no matter what kind of brushing method should avoid excessive force, and the use of soft-bristled toothbrush, and those parts of the toothbrush is difficult to reach such as the last teeth of the distal and middle surface and the gap between the two teeth, you need to use dental floss or interdental brushing to assist in cleaning.
