Brush your teeth vigorously, don't brush your teeth without sugar, and avoid tooth washing

          For most people, teeth are not only a simple need for eating and chewing, but also the most important part of "image engineering". Fu Yun, associate professor, director of the Department of Periodontology, Affiliated Stomatological Hospital, Guanghua stomatological college, Sun Yat sen University, said that healthy teeth are one of the most precious treasures in life, so we should cherish teeth and pay attention to oral health care. Improper use of some methods that are supposed to take care of teeth will cause many oral diseases, even systemic diseases or aggravate the original diseases.

          Mistake 1: brush your teeth more cleanly

          Some people, especially young people, are used to brushing their teeth vigorously, thinking that this can better clean their teeth. Not really. Long term vigorous brushing will lead to tooth defects. The wedge-shaped defects of many middle-aged people's teeth are caused by long-term vigorous brushing.

          Correct practice: Brush teeth with soft and elastic bristles, brush teeth with moderate strength, and pay attention to the method of brushing teeth, so that the teeth can be clean and will not be damaged to the teeth and gums.

          Mistake 2

          The more expensive the toothpaste, the better

          Some people have such shopping habits, think that expensive is good. In fact, when brushing teeth, toothpaste acts as a friction agent, which can effectively remove the dental plaque in some small concave parts of the tooth surface. However, the key to better remove the plaque in the crevices and pits is not the brand and price of toothpaste, but whether the method of brushing teeth is correct.

          Correct way: instead of pursuing expensive toothpaste, choose fluoride toothpaste.

          Mistake 3

          No toothache is no tooth disease

          Many people think that the standard to measure whether the teeth are healthy is whether the teeth are painful or not. They think that if the teeth are not painful, there is no dental disease, and there is no need to see a doctor regularly. This is wrong.

          Fu Yun pointed out that in the early stage of oral diseases, such as dental caries and periodontal disease, there is generally no discomfort or pain. Once you feel the pain, it shows that the degree is serious. It takes at least one year for adults to feel pain from the beginning of a tooth decay, and it will be shorter for children; So is the development of periodontal disease.

          Correct practice: adults and children should have dental examination once a year and half a year to find teeth and periodontal problems as soon as possible.

          Four Misunderstandings

          It doesn't matter when you brush your teeth

          Brush your teeth two or three times a day, but every year when you wash your teeth, the doctor says that there is a lot of tartar. What's the matter? Fu Yun pointed out that brushing teeth is not about how many times, but when.

          Many people have a good habit of brushing their teeth after getting up in the morning and before going to bed at night, but they don't have the habit of brushing their teeth regularly after meals, which is insufficient. Studies have found that after eating, food residues attached to the surface of teeth will be used by bacteria in dental plaque after 10-20 minutes, producing acid substances to damage teeth.

          Correct practice: in addition to brushing teeth in the morning and evening, you should brush your teeth or gargle within 10 minutes after meals, and clean your mouth as soon as possible, so as to destroy the environment of bacterial growth and reproduction.

          Mistake five

          No sugar, no tooth disease

          Eating less or no sugar can reduce the incidence of dental caries, but sugar is not the only source of oral bacteria damage teeth. Starch in bread, steamed bread, rice and other carbohydrates will also produce small molecular sugar after oral hydrolysis, which is also easy to be used by bacteria in the mouth.

Correct practice: in addition to eating less sugar, it is more important to gargle or brush your teeth as soon as possible after meals.

          Six misunderstandings

          Drug toothpaste can treat periodontal disease

          Some people think that medicated toothpaste can be used to treat gingival "inflamed" and periodontal disease. When there is gingival swelling, pain and bleeding, they don't see a doctor in time, but blindly use medicated toothpaste to "reduce fire".

          Fu Yun said that gingivitis and periodontitis are mostly caused by local dental calculus and plaque stimulation. Medicated toothpaste has the effect of heat clearing and detoxification, so it can indeed play some effects in the early stage of gingivitis. However, they can not remove dental plaque, dental calculus, and the root cause of inflammation, so they can only treat the symptoms but not the root cause.

          Correct practice: gingivitis, periodontitis attack should see a doctor, daily should do a good job in tooth cleaning, tooth washing to prevent gingivitis, periodontitis.

          Seven misunderstandings

          Washing your teeth will destroy them

          Many people feel that their teeth are soft and sour after tooth washing, and they feel uncomfortable eating sour and sweet food. They think that tooth washing has hurt their teeth. This is absolutely a misunderstanding.

          At present, ultrasonic cleaning is widely used in hospital tooth washing, which relies on the ultrasonic vibration of ultrasonic instruments to remove dental calculus and plaque, rather than grinding, and does not cause damage to the hard tissue of teeth.

          Why does the tooth have acerbity soft feeling after washing a tooth? That's because people who haven't washed their teeth for many years have a lot of stones on the tooth surface, which are not only thick, but also cover most of the root. Because the calculus attached to the root surface, it seems to "protect" the root, usually do not feel too much discomfort. After tooth washing and removing calculus, the root of the tooth is exposed. When encountering cold, hot, sour and sweet food, the teeth will feel sour and soft for a period of time, but this feeling will gradually ease.

          Correct practice: if there is pain after tooth washing, it is only temporary, wait for it to ease slowly. As long as adhere to the annual tooth washing, teeth are relatively clean, this feeling rarely occurs.

          Eight misunderstandings

          Old teeth are bound to fall off

          The World Health Organization (who) put forward the "8020" plan on September 20, 2001, which means that 80 year old people should have 20 healthy teeth. Therefore, it is not reliable to say that the old teeth must fall off.

          Correct practice: healthy teeth accompany to old age is not a dream, as long as we develop good oral hygiene habits, eat more food that is conducive to tooth cleaning and health, pay attention to balanced nutrition, regularly check the oral cavity, scientifically care for teeth, often use tea to gargle, frequently do tooth tapping and gum massage.
