Brushing teeth is the most effective way to remove and control dental plaque. All kinds of brushing methods are popular now. Most people use the customary brushing method, that is, brushing their teeth horizontally or brushing their front teeth vertically and pulling their back teeth horizontally to clean their teeth. Ordinary brushing methods can only clean dental plaque and food residue on buccal, lingual and occlusal surfaces, and it is difficult to thoroughly clean the adjacent surfaces between teeth. Today we will tell you what kind of toothbrush to choose and how to brush your teeth correctly.
Since the commercial toothbrush was manufactured in Europe in 1780, the toothbrush has played an important role in human oral health care for more than 200 years. Early people used natural bristles as bristles for a long time; After 1938, nylon filaments were used as bristles. After 1940s, soft nylon filaments and round-headed toothbrushes were introduced abroad to prevent tooth damage and tooth decay. According to the experimental test, the wear depth of the pointed-hair toothbrush with a diameter of 0.303mm is 3.9 times higher than that of the round-hair toothbrush with a diameter of 0.20 mm, and after 75,000 rubs, the tooth wear depth of the former is 3.9 times higher than that of the latter. The diameter of bristles is basically the same, and the teeth at the tip are more worn than those at the round end.
The clinical and epidemiological data of small toothbrushes and universities also show that the wedge-missing rate of people who use big-headed coarse-haired toothbrushes is as high as 47.78%. For those who use healthy toothbrushes, the wedge vacancy rate is only 2.08 months. These results are enough to prove that the big-headed coarse-bristle toothbrush is the main cause of wedge-shaped tooth defect in middle-aged and elderly people in China. The adult toothbrush standard formulated by the Ministry of Health, the Ministry of Light Industry and the Ministry of Commerce 1978 stipulates that the diameter of bristles is 0.2 ~ 0.03 mm, which seems to be too large, and there is no clear regulation on brushing the Mao Mao end. It is suggested that the standards for healthy toothbrushes should be re-formulated, in which the diameter of nylon filament for adult toothbrushes should be controlled at 0. 18 ~ 0.022 mm, and the ends of bristles should be smooth.
Illness caused by improper toothbrush The tooth loss rate of middle-aged and elderly people with brushing habits is 43.08%, of which 30.5 1% is complicated with dental pulp and periapical periodontitis. According to a preliminary estimate, there are about 60 million middle-aged and elderly people who have the habit of brushing their teeth in such a large population of China. According to our investigation results, about 25.8 million middle-aged and elderly people who have the habit of brushing their teeth may suffer from wedge-shaped defects, and about 7.8 million people suffer from dental pulp and periapical periodontitis. In fact, many young people who have the habit of brushing their teeth suffer from wedge-shaped defects. Therefore, we suggest that relevant parties pay attention to this problem related to people's health and take effective measures.
What kind of toothbrush do you choose? Recommend a soft toothbrush. Although the bristle toothbrush is particularly powerful to brush, it is easy to hurt teeth and gums. If you feel a little pain when brushing your teeth, change to a soft-bristled toothbrush. But you don't have to choose these, okay? Super soft. Super soft? Yes, it's too soft and the cleaning effect is not good enough.
How to brush your teeth After choosing a soft-bristled toothbrush, place the toothbrush at 45 with the long axis of the teeth. Point to the apical direction (maxillary teeth up, mandibular teeth down), press the gingival-dental junction area, so that one part of the bristles will enter the gingival sulcus, and the other part will spread out on the gingival margin, reaching into the adjacent gap as far as possible. With a slight pressure, the bristles will horizontally vibrate back and forth for a short distance 10 times. When vibrating, the toothbrush only moves about 1mm, brushing 2 or 3 teeth at a time. When moving the toothbrush to the next set of teeth, pay attention to overlapping placement. If the lingual side of the anterior teeth is narrow, the toothbrush can be vertical, and the bristles can be pressed into the gingival sulcus and the adjacent gap by about 45? Angle, short vibration to the long axis of the tooth. The action of maxillofacial brushing is to press the bristles tightly on the maxillofacial region, so that the ends of the bristles go deep into the gap and vibrate in the direction of the front and rear teeth.
Finally, it is emphasized again that brushing teeth can mechanically remove dental plaque and soft dirt, and massaging gums can enhance the disease resistance of periodontal tissues, which is an important method to keep the mouth clean and prevent oral diseases. Because of its simplicity and low price, brushing teeth has become the most accepted and popularized oral hygiene measure by the masses.
