美容冠排齐牙齿？
Beauty Crown align teeth?
万恶之首，当推美容冠。这是非正规医疗场所为了得到暴利收入而开发出来的概念，不属于医学范畴。许多有小虎牙的女孩，其实很可爱，但看到所谓的：七天快速排齐牙齿，一心动便去磨小本不用磨掉的牙齿成分，套上外观美丽但毫无必要的「大白牙」。结果却在几个月或几年后因为牙周炎、龋齿或牙髓炎回到医院拆掉这些「美丽」的累赘。
The root of all evil, when pushing beauty crown. This is a concept developed by non formal medical establishments for the sake of huge profits, and does not belong to the medical category. There are many small teeth girl, actually very cute, but see the so-called seven day fast alignment of the teeth, the teeth move to grind small components on the do not wear off, a beautiful appearance but without the "big white". But in the months or years later because of periodontitis, caries or pulpitis returned to the hospital to pull down the "beautiful" burden.
片面追求快速，强行通过磨除过多的牙本质等方式将牙齿改造，其后果不仅是损伤牙本质，更可能损伤健康的牙髓神经，引发炎症。由于要「七天」装上牙齿，受到刺激的牙龈往往没有时间恢复自然的外形和高度，就要受到义齿的挤压和刺激，然后处于长期的外部刺激，最后引发牙周炎。
The one-sided pursuit of speed, forcing the teeth by grinding too many teeth and other ways to transform the teeth, the consequences are not only damage the dentin, is more likely to damage the healthy pulp nerve, causing inflammation. Due to the "seven days" with teeth, gingival irritation often do not have the time to restore the natural shape and height, they are subject to the denture extrusion and stimulation, and in the long run the external stimulus, and finally lead to periodontitis.

拔牙能瘦脸？
Extraction can face lift?
巴掌脸是许多女生心中追求美丽的标准之一。为了瘦脸，大家各显神通，有人减肥，有人打瘦脸针。近年来，被部分女明星带起来的「拔牙正畸」的瘦脸风潮也影响不小。许多人认为，拔掉几颗「智齿」或为了正畸扩大牙弓间隙的「正畸牙」就能够让下颌角小一圈。
Palm face is one of the criteria for many girls to pursue beauty in their hearts. In order to face, we Gexianshentong, some people lose weight, some people play thin face needle. In recent years, some women stars brought up "tooth extraction orthodontic" face lift trend also affected. Many people believe that a few "wisdom teeth" or "orthodontic teeth" that extend the arch of the tooth for orthodontic treatment can make the mandibular angle a little wider.
在这里，小助手明确告诉大家：正规治疗手段拔除的牙齿并不能改变脸型。人脸的宽度是由颧骨、下颌骨和咬肌等结构支撑起来的，而这些结构在人成年之后就趋于稳定，只会因为长期的咬合习惯带来微小的外形改变（比如偏侧咀嚼带来的双侧咬肌大小不同，从而造成脸部不对称等），并不会因为牙齿少了一颗，脸部就会瘦一半！
Here, the little assistant specifically tells you: regular treatment means that the extracted teeth can not change the face shape. The width of the face is held up by zygomatic bone, mandible and masseter muscle structure, and these structures in adulthood is stable, only because of occlusion habits of long-term minimal shape (such as Hemimastication brings the bilateral masseter muscles of different sizes, resulting in facial asymmetry), and not because of missing teeth a face will be thin, half!
拔牙瘦脸很多时候是因为短期的肿胀在消肿后带来的对比或者咀嚼习惯的改变带来的面部对称问题引起，并不是真正的「瘦脸」。想拥有一张小脸，七分靠基因，三分靠减肥或者医疗美容，目前牙医们还没研发出确定有效的瘦脸方式。
The extraction of a face lift is often caused by a short-term swelling that results from a facial symmetry problem caused by a contrast or a change in chewing habits. It is not a real "face lift.". Want to have a little face, seven by gene, three by weight loss or medical beauty, at present, dentists have not yet developed an effective way to determine face lift.

漂白牙齿多做几次，牙会白？
Bleaching teeth do more times, the teeth will be white?
常听到的「牙齿漂白」或「牙齿美白贴」是牙医们经常接触的医学概念。那么，是不是漂白做多几次，牙齿就会越来越白呢？
Dental bleaching or tooth whitening paste is often a medical concept that dentists often come into contact with. Well, is not bleaching done more than a few times, the teeth will become more and more white?
首先，牙齿的色泽是天生的牙本质和牙釉质的颜色决定的。钙化完全且健康的牙釉质是微黄半透明带着珍珠光泽的，这种微黄颜色的深浅决定了一个人牙齿的颜色。
First, the color of the tooth is determined by the nature of the dentin and the color of the enamel. Fully calcified and healthy enamel is yellowish translucent with a pearl luster, and this yellowish shade determines the color of a person's teeth.
对于有活性的牙齿，牙齿漂白通常是无创地通过化学药物的渗透，置换出牙齿表面的色素或磨除沉淀的污渍（外漂白）。而这种漂白的极限效果是牙齿的天然色，若一个人本身牙釉质颜色较深，不论怎么漂也不能够让它变得白如釉瓷。
For active teeth, the bleaching of teeth is usually done by non-invasive penetration of chemical drugs, displacing the surface of the teeth or removing stains (outer bleaching). This is the ultimate effect of bleaching teeth natural color, if a person is enamel color is deep, no matter how drift can not let it become white as porcelain.
其次，由于使用的化学药物有一定刺激性，且对牙齿钙化有一定的影响，多次的漂白不仅不能让牙齿越来越白，反而会影响牙齿和牙周的生理健康，得不偿失。想要一口白牙，保持良好的饮食和生活习惯，不吸烟，少喝着色性饮料，刷牙严格规范。
Secondly, because of the chemical drugs have a certain irritation, and has certain effects on dental calcification, multiple bleaching not only can not make more and more white teeth, it will affect the physical health of the teeth and gums, The loss outweighs the gain. You want a white teeth, maintaining good eating and living habits, do not smoke, drink less colored drinks, strictly regulate the brushing.

修复义齿选材料「越白越好」？
Repair denture selection material: the whiter the better?
在不得不用贴面、冠等方法进行义齿修复时，往往会有很多人想要选择尽可能白的材料制作义齿。殊不知，美学修复早已经跨过「越白越好」的误区，走向健康自然的领域。
Many people would like to choose the material as white as possible to make dentures when they have to use the veneers and crowns. As we all know, aesthetic repair has already crossed the "whiter the better" misunderstanding, toward the healthy and natural fields.
一口美丽的牙齿，首先要是和谐、自然的，其次才是色泽白净。一味将义齿颜色调白，只会让修复义齿效果「僵硬」，造成和其他牙齿不协调的滑稽效果，让人一眼看出你有一颗「雪白的假牙」。自然美不仅适用于面容的美丽，也适用于口腔修复的各个领域。
A beautiful tooth, first of all, harmonious, natural, and then the color is fair and clear. Simply turning the color of the denture into a white will only make the restoration of the denture "rigid" and produce a funny effect that does not mix with the other teeth. It shows that you have a "white false tooth". Natural beauty applies not only to the beauty of the face, but also to every field of dental repair.
前半生苦苦追求的「大白牙」早就过时啦，要听取牙医的意见，选择适合自己的天然颜色进行义齿修复！
The first half of the pursuit of the "big white" out of date, to listen to the dentist comments, choose their natural color of denture!
总结：
Sum up:
这些乱来的修复方式，你经历过吗？让我们抛弃它们，选择自然、健康、美观的修复方法吧！
