There are many "conscience" suggestions circulating on the Internet: Never wash your teeth! Washing teeth will wash bad teeth and cause hidden cracks on the surface; Gingival recession causes the gap between teeth to become larger, resulting in occlusion; Loose teeth and so on. Brush your teeth twice a day and your teeth will be clean. You don't need to wash them at all.
Rumor text:
Tooth washing is called tooth cleaning in medicine, which is the most basic and effective method to prevent periodontal disease. 20 18 The Chinese Stomatological Association put forward eight principles of loving teeth, one of which is: "In order to keep teeth firm and periodontal health, it is best to clean teeth once a year."
Why do some people feel uncomfortable after washing their teeth? Washing teeth will not cause problems such as loosening, soreness and widening of teeth. The real causes of discomfort are gingival atrophy, redness, bleeding, alveolar bone absorption, loosening, root exposure and widening of tooth space (gap) caused by dental calculus and dental plaque adhering to tooth surface.
Without medication, dental calculus adheres between teeth, temporarily sticking the teeth like glue, and the teeth look more stable on the surface. However, with the accumulation of dental calculus on the tooth surface, its volume is getting bigger and bigger, which will press the gums to retreat to the root. After a long time, the teeth that were originally full of gums were also filled with thick dental calculus.
Because the accumulation of dental calculus on the surface of teeth is a slow process, people usually feel foreign body sensation less easily. However, in the process of tooth cleaning, when the calculus is removed, the gap between teeth will be exposed instantly, and the root without calculus will also be exposed. At this time, people often feel uncomfortable, their teeth will be unable to loosen, and their teeth will widen.
So, will tooth washing "wash teeth"? It is out of the question. At present, ultrasonic scaling is widely used. Because the ultrasonic scaler produces high-energy ultrasonic with a specific frequency, it is only effective for calculus and pigment on the tooth surface, and will not damage the teeth and cause cracks on the tooth surface. A healthy tooth surface is a layer of enamel, which has the highest hardness in the human body. The rubber wheel for polishing is soft and won't wear teeth.
So, as long as you brush your teeth twice a day, can you keep your mouth healthy? The World Health Organization (WHO) defines oral health as "clean teeth, no cavities, no pain, normal gum color and no bleeding." Oral health, oral infection and inflammatory factors can lead to or aggravate cardiovascular and cerebrovascular diseases, diabetes, Alzheimer's disease and other chronic diseases. , thus endangering the whole body health and affecting the quality of life.
20 19 September 20th is the 3rd1national love teeth day. The publicity theme is "oral health, general health", and the sub-theme is "brushing teeth, gargling, flossing teeth, protecting gums and promoting health". Daily dental care is not only the routine brushing twice, but also the principle of "brushing and flossing, cleaning teeth, protecting gums and promoting health".
First of all, we must understand the "culprit" dental plaque that harms the mouth. Dental plaque is a kind of bacterial biofilm, which is a soft non-mineralized flora wrapped by matrix and adhered to teeth, teeth or restorations. Dental plaque adheres to the tooth surface, which is thin and colorless and difficult to observe. After being taken out, it constantly re-forms on the tooth surface, and finally calcifies to form dental calculus. Timely and effective cleaning of teeth and removal of dental plaque and calculus are the basis for preventing and delaying periodontal disease.
Many people think that they brush their teeth "seriously" every day. In fact, they don't have a scientific method of brushing their teeth. They just brush their teeth according to their habits. It is inevitable that some parts of the brush are not in place, especially the cleaning between the teeth and the lingual side of the lower anterior teeth is easily overlooked.
At present, the Chinese Stomatological Association recommends the use of horizontal vibration brushing: horizontal vibration mainly removes dental plaque from the neck and gingival sulcus, and brushing mainly removes dental plaque from the lips (cheeks) and tongue (palate).
The specific operation is as follows: put the brush head on the neck of the tooth, with the bristles pointing in the direction of the root (the maxillary teeth are upward and the mandibular teeth are downward), and the included angle between the bristles and the long axis of the tooth is about 45 degrees. Gently press, so that part of the bristles enter the gingival sulcus and part of them are placed on the gums. Start brushing your teeth with 2-3 teeth as a group, shake the toothbrush horizontally for a short distance, and the bristles turn into bite.
Brush 10 times at least at the same position, then turn the toothbrush to the crown and continue to brush the lip (cheek) and tongue (palate) surfaces of the teeth; After brushing the first part, move the toothbrush to the next group of 2 ~ 3 teeth for repositioning, pay attention to the overlapping area with the first part, and continue to brush the next part; When brushing the lingual surface of the front teeth, put the brush head vertically on the lingual surface of the teeth, so that the front bristles contact the gingival margin and brush from top to bottom. When brushing the lingual surface of the anterior teeth, brush from bottom to top; When brushing the occlusal surface, the bristles point to the occlusal surface and brush back and forth for a short distance with a little force.
After mastering the correct brushing method, you should also choose a suitable toothbrush: the brush head is small, the bristles are soft, the ends of the bristles are round, the bristle clusters are 3-4 rows, and the toothbrush handle is easy to hold; Try to choose fluoride toothpaste. Fluoride deposition on the surface of teeth can enhance the remineralization ability of teeth. The amount of toothpaste is shown in the figure.
Brush your teeth after meals, 2-3 times a day, and brush your teeth effectively for at least three minutes. If you can't brush your teeth after meals, rinse your mouth and brush your teeth before going to bed. Dental floss interdental brushes should be used to clean the adjacent surfaces of teeth. To sum up: brush your teeth, rinse your mouth and floss.
However, brushing teeth can't remove the calculus formed by calcification of dental plaque. If dental calculus has formed, you should go to a regular hospital to wash your teeth. Dental calculus contains a large number of bacterial toxins, which will lead to gingivitis and even periodontitis if it stays for a long time. Once periodontitis is diagnosed, sequential periodontal treatment is needed, and tooth washing is one of the basic periodontal treatments. Therefore, you must be responsible for your oral health and don't blindly refuse to wash your teeth. To sum up: clean teeth, protect gums and promote health.
