Tooth extraction is almost always a major concern for patients, as orthodontics is a long and grueling process, and patients or their parents are usually more determined. The high cost can be tolerated, the long time can be tolerated, but often when the doctor says that four teeth have to be extracted, many people back off. That’s why I’m going to explain the common problems in layman’s terms. The first thing to state is that the removal of wisdom teeth (the third largest tooth from the center) is not part of the discussion. Even without orthodontics, most people still have a need to have their wisdom teeth removed. This is especially true for blocked wisdom teeth that have not erupted into their normal position, which can have a negative impact on other teeth if not removed. When determining whether or not an extraction is necessary, our doctors usually have two main considerations, one being the side profile and the other being the degree of crowding. As you can imagine, if a patient with protruding teeth has very crowded teeth, if they are forced to align without extraction, I am afraid they will become Peking apes… So before the consultation, if you have very crowded teeth, or you have a very protruding side profile, then you need to be psychologically prepared for the possibility of having your teeth extracted. Many patients say, “Well, I’m not willing to sacrifice healthy teeth to achieve aesthetics… health is more important than aesthetics. In fact, this is a misunderstanding, the appropriate extraction of teeth not only will not harm the health, but can promote health. First of all, if the teeth are crowded, it can not be efficient cleaning, long-term, gingivitis, periodontal disease will greatly increase the probability, and even cause tooth loss; Secondly, orthodontic treatment establishes a good occlusion, to avoid the teeth of the adverse force, is conducive to the improvement of the efficiency of mastication; Finally, but also to say a few words about the location of the extraction of the selection of the teeth, we are most often extracted from the premolar teeth (that is, the fourth or fifth tooth), why? ), why? Simply put, the front incisors (incisors) need to be used to cut off food, and cuspids (tiger teeth) used to tear food, and these six teeth have great aesthetic significance, so these teeth can not be extracted; and the back of the molar (big teeth, groove teeth) to be used to chew food, people can not not not to eat, to reduce the efficiency of mastication is absolutely not, so can not be extracted. The function of the remaining premolar teeth is to assist other teeth, some statistics, the loss of chewing efficiency by removing four premolar teeth is only about three percent. And some patients, originally due to other teeth are not aligned, the upper and lower teeth can not bite together, and after the removal of premolar, the other teeth can be aligned and can play the function of chewing again, the total chewing efficiency is improved. However, there are many modes of clinical extraction, and not all of them involve the removal of premolar teeth. It is important to analyze specific problems, and qualified doctors will consider various factors to achieve the best aesthetics and function. Therefore, if you can tolerate a long procedure and high cost, then the problem of tooth extraction should be even less of a problem for you, the key is your mindset.
