I. How to know whether the brushing method is correct To achieve oral hygiene, the main method is to master the correct brushing method and achieve effective brushing. Effective brushing means that the bacteria attached to the surface of the teeth are effectively removed by brushing. To check whether the bacterial plaque has been removed, you can apply plaque stain on the teeth before and after brushing, if there is no coloring, it means the teeth are clean, if there is red coloring on the tooth surface, it means the teeth are not clean. Second, buy electric toothbrush to brush teeth, is it sure to brush clean? The effect of brushing depends mainly on the method of brushing, and it is generally recommended that children and people who are not very handy use electric toothbrushes. When brushing, the force of pressure should be heavy, but the force of brushing should be light, the magnitude of back and forth should be small, especially the force of pulling back and forth should be light, otherwise the things in the gap of teeth are not removed, but will damage the tooth surface. To follow a certain order of brushing, all parts of the teeth should be brushed, especially the inside of the back teeth. To insist on brushing every morning and evening, it is even more important to brush your teeth at night before going to bed, and each time should be no less than 3 minutes. Third, is there a point in choosing a toothbrush? Toothbrushes should be small, soft, bristly and with a handle that is easy to grasp. Replace your toothbrush at the right time. When the toothbrush bristles begin to bend outward, it is time to replace the toothbrush. In general, the toothbrush should be replaced once every three months. Fourth, how to choose toothpaste in the mall In fact, the most important thing is the correct method of brushing, toothpaste only plays a supporting role. As long as the brushing method is correct, even if only a little water brush, can also achieve very good results. The main component of toothpaste is a friction agent and contains surfactants, which can increase the role of plaque removal when brushing teeth. In many families, everyone shares the same toothpaste, but in fact, each person can listen to the doctor’s opinion when choosing toothpaste according to their dental condition. Fluoride toothpastes, like those containing fluoride, can help repair enamel at the early stages of tooth decay and neutralize acid-producing plaque. If your doctor recommends a particular toothpaste, such as an anti-allergy toothpaste or a descaling toothpaste, they may not be right for your family. V. Is it better to floss or floss with toothpicks? For the area where plaque tends to accumulate – the gaps between your teeth – besides brushing, insisting on flossing is the best way to go. Some people think that flossing in and out of the teeth can lead to loosening of the teeth, so they are afraid of it, but this concern is superfluous, because the normal gap between teeth is enough for a very flat floss to pass through. The toothpick can only be used in cases of gum papillae atrophy and large gaps in the teeth, and the tip should be inserted towards the tooth joint surface to push out the food in the horizontal direction. VI. Is it a serious problem if I bleed a lot when brushing my teeth? Bleeding teeth often indicate the possibility of gingivitis, and the development of gingivitis is periodontitis. The consequence of periodontitis is more serious than tooth decay. While tooth decay is bad for one tooth, periodontitis can cause several teeth or even a full mouth to fall out. When gingivitis has symptoms such as bleeding and bad taste in the mouth, don’t think that chewing gum will solve the problem. When it develops into periodontitis, there will be swelling and pain, loose teeth and even loss of teeth. And once it develops to the advanced stage of periodontitis, it is difficult to treat; nowadays, there is a trend of early onset of periodontitis age group, many people in their 30s to 40s have loose teeth, and there are also patients in their 40s who had to have their mouth full of teeth extracted due to periodontitis. Seven, will scaling damage the teeth? The timely cleaning of plaque and calculus in the mouth by means of ultrasonic scaling is what people call “scaling”, which is one of the main means of preventing periodontal disease. As long as the scaling method is correct, there will be no damage to the teeth. Foreign dental assistants use a magnifying glass to check the teeth’s finish after scaling. So the most important thing is to choose a good hospital to clean your teeth and not just find a small unregulated clinic to clean your teeth. Some people think that as long as you brush your teeth carefully, you don’t need to “clean your teeth”, but this is not true. If we do not pay attention to oral hygiene or brushing method is not correct, there will be a large amount of plaque accumulation on the surface of teeth, especially the parts that can not be brushed by toothbrush, which will become calculus over time. If you have periodontitis, you should go to the hospital every 3-6 months for a review, and if there is new tartar, plaque or calculus, you can have your teeth cleaned again. For normal people, a review should be done once every six months to once a year. However, it is important to remember that “scaling” alone to prevent periodontal disease is not an option. Question 8: Should I get a tooth after it is extracted? Answer: If a tooth is missing, you will not feel the change for a while. But after 10 or 20 years, there will be problems, all the teeth on the side will be shifted, the opposite teeth will be elongated, and the whole tooth row will be changed, so it is necessary to set the teeth in time after extraction. Eight, how many teeth can be retained, do not easily extracted? Indeed, don’t pull out the teeth rashly after they have problems. Some middle-aged and elderly people, when their teeth are almost gone, ask for extraction to set full teeth, while full teeth exercise very limited function in occlusion. Especially if the teeth are extracted due to periodontitis, the condition of the alveolar bone is very poor and it is difficult to wear firmly. If you can leave a few useful teeth or roots, you can greatly increase the effect of dentures. However, some should be extracted still have to be extracted, like unusable tooth stumps, advanced periodontitis, etc., according to the doctor’s judgment to decide whether to extract. Nine, porcelain teeth can be cosmetic, but also the teeth can be set up to protect the teeth? Do porcelain teeth to protect healthy teeth argument is not justified. If you do porcelain teeth purely for cosmetic reasons, you should still consider carefully, any treatment has side effects. Suitable for porcelain dental restoration of teeth about 5 categories: 1, missing teeth, generally requires a small number of missing and healthy adjacent teeth, no inflammation or inflammation, but after treatment to control, after examination by the doctor, unwilling to implant restoration, can consider doing porcelain dental restoration; 2, is the color or shape of the teeth is not good, such as tetracycline teeth, conical small teeth; 3, is an abnormal shape of the teeth and not suitable for orthodontic Patients with abnormal tooth shape and not suitable for orthodontic treatment can be considered for porcelain restoration; 4.The teeth broken by trauma or residual roots, if the roots have sufficient length and the periodontal situation is good, after perfect root canal treatment, porcelain restoration can be done; 5.The teeth with large caries or tooth defects, discolored gray or yellowish brown, can be restored by porcelain restoration and increase the strength.
