“Consistent removal of plaque throughout life is the most effective means of maintaining oral health.” This has long been a consensus in developed countries and regions. Brushing is the most important means of removing plaque on a daily basis. To improve the quality of brushing, we must first raise the awareness of oral health care. With the right attitude, another important issue to be solved to improve the quality of brushing is the way of brushing. The brushing method is the most important. We recommend the Bachmann brushing method, which effectively cleans the teeth and gum sulcus, prevents plaque accumulation and stops the formation of calculus, and effectively prevents and treats periodontal disease. Tilt the toothbrush 45° toward the root of the tooth, place it on the edge of the gum and gently press to let the bristles enter the gingival sulcus; move the toothbrush back and forth in groups of 2-3 teeth, chattering at least 10 times, then move to the next group. Brushing tools: toothbrush, far more important than toothpaste, which only plays an auxiliary role. Please choose a health care toothbrush, brush head should be small, too big and too small are not conducive to control the direction and parts of brushing, bristles soft and hard moderate, too hard easy to cause unnecessary damage to teeth and gums, too soft to reduce the efficiency of brushing; conditions can also choose electric toothbrush; but the key is the correct method of brushing. Toothpaste can be chosen according to personal taste, but you should not hope for the efficacy of drugs. The timing and time of brushing. It is recommended to brush your teeth once a day in the morning and once a day in the evening, at least three minutes each time is very critical. To ensure the timely removal of plaque on the teeth. Special attention should be paid to the equitable distribution of time between the inside and outside of the front and back of the teeth when brushing, and the same attention should be paid to the back teeth and the inside (lingual side) as well as the front teeth and the outside (labial side). Clinically, it is often found that the outer and anterior teeth are relatively clean, while the inner and posterior teeth have thick deposits of soft tartar pigmented tartar. The use of dental floss is important. Conventional brushing can only clean the labial, lingual and occlusal surfaces of the teeth, but the adjacent surfaces (interdental spaces) that are in contact between the teeth cannot be reached. For normal gaps, flossing is the best option. Flossing is recommended at least once a day to complement brushing. Flossing is a skillful process, and it is normal to feel poorly controlled in terms of direction and location at first, but it often causes many people to lose confidence and give up flossing. In fact, after some professional guidance or following the relevant instructions (text, pictures, videos) and some exercise, you can master the use of dental floss.
