Wisdom teeth (wisdom teeth), the eruption of which in a sense represents the maturation of an individual’s development, have been documented to erupt between the ages of 16.5 and 26. At this stage, wisdom teeth often bring us some small troubles. In the face of wisdom teeth “going” and “staying”, how should we make a choice. We will explain here the common problems encountered in the clinic. First, what are wisdom teeth? Wisdom teeth are the third molars, one on each side. In fact, there is no essential difference between wisdom teeth and other teeth, they are also normal growth of teeth. As human chewing organs deteriorate with the increasingly refined diet, the deterioration of teeth is relatively slower than that of the jawbone. Many people’s third molar can not erupt, and even if it does, it can not establish a good occlusal relationship. Second, do all wisdom teeth have to be removed? Of course not. Many people’s wisdom teeth can erupt to their normal position and establish a good occlusal relationship. There are times when we encounter decay or loss of the mandibular second molar, the prosthodontist may need to utilize the wisdom tooth as an abutment; orthodontists may also have a way to make the originally tilted and blocked wisdom teeth upright, which requires a professional doctor’s examination before a decision can be made. In which cases should wisdom teeth be removed as soon as possible? 1, repeatedly cause inflammation. The most common danger of wisdom teeth is pericoronitis, because there is a blind pocket between the teeth and gums, in the encounter of low body resistance or food debris, etc. into the blind pocket when it is possible to attack. The degree of inflammation varies, the mild may only feel uncomfortable for a few days; the serious may cause septic infection of the facial space, and even systemic symptoms of poisoning. 2, wisdom teeth caries. If the wisdom teeth are seriously decayed, it is generally not recommended to repair or do root canal treatment. There are three reasons: wisdom teeth are very backward, the treatment is more difficult; wisdom teeth mutation is more, the treatment effect may not be ideal; wisdom teeth in the filling treatment, if you can’t maintain good oral hygiene, it is more likely to reoccur caries. 3.Food impaction. If the wisdom teeth and the front of the teeth between the teeth are always stuffed, even if the wisdom teeth grow more “positive”, it is also recommended that you as soon as possible to pull out the wisdom teeth. The reasoning is like “losing the car to save the king”. Food impaction can easily cause caries in the front second molar and may trigger periodontal damage on its distal and middle surfaces. 4. Wisdom teeth tilted proximally. Wisdom teeth that are tilted proximally may cause food impaction. In some cases, wisdom teeth can grow to the point where they are directly on top of the roots of the second molars. In this case, it is better to remove them as soon as possible, because it is often encountered in the clinic that the wisdom teeth will be the top of the second molar broken and need to remove both teeth at the same time, once this happens, it is really a pity. 5. Cysts or tumors. Individual wisdom teeth may eventually develop into odontogenic cysts or tumors. In fact, it is not only wisdom teeth that may cause this, but also other blocked teeth, such as blocked cuspids or supernumerary teeth. It is usually more common with completely buried teeth, and it is up to the patient to decide whether or not this tooth is extracted. Maxillofacial surgery textbooks do not have a clear definition, only that can be “temporarily retained. 6, orthodontic needs. Orthodontist will make a detailed description of this situation. Clinically, sometimes orthodontists will ask for early removal of wisdom teeth when the roots have not developed, sometimes even at the age of 14 years old or so come to ask for the removal of wisdom teeth, generally seen in patients with anticompatibility, early removal of wisdom teeth may be conducive to the control of the development of the posterior segment of the mandible length. 7. Prevent crowding of teeth. Under normal circumstances, the teeth have a tendency to move forward, which can ensure that the teeth adjacent to the surface of the physiological abrasion does not appear in the case of gaps. The eruption of wisdom teeth, especially near the center of the growth of wisdom teeth, may make this movement become “abnormal”. Some people will tell the doctor that after the age of 30, the lower front teeth become more and more uneven, and the growth of wisdom teeth may be one of the reasons for the normalization of this situation, and now many scholars agree with this viewpoint. Does wisdom teeth extraction hurt? This is a question that no one facing wisdom teeth removal will ask, and the answer is “no pain” and “pain”. The answer is “no pain” and “pain”. “No pain” means that the extraction process is painless, and you will not feel any pain when wisdom teeth are extracted under good local anesthesia. If there is serious mental tension, you can also choose to extract the tooth under laughing gas sedation and analgesia, or even under general anesthesia to remove it. Several friends abroad have had all four wisdom teeth removed with the help of laughing gas. “Pain” means pain after extraction. Overall, the removal of the lower wisdom teeth does hurt, and having a painkiller ready after the extraction can make you feel much more comfortable after the anesthesia wears off, and can ensure that you can have a good night’s sleep (personal experience). The pain after wisdom tooth removal is not only in the wound, but it can also cause pain in swallowing. However, pain varies from person to person, and there are many patients who come back to have their stitches removed who respond that they do not feel any significant pain. After all, whether it hurts or not, and the degree of pain is at some point a subjective response.
