The child has tiger teeth, which is very cute, but the tiger teeth extruded from the normal position and outward, a mouth, two “fangs” like a knife edge in the eyes, an eyesore. For this reason, many parents take their children to the hospital and ask to be pulled out. The tiger teeth on both sides of the human mouth bear the weight, bite and power transmission role, arbitrarily remove or increase the possibility of dental caries and affect the fullness of the face. Therefore, it is better to choose orthodontic treatment than to blindly remove them in order to save trouble. Tiger teeth do not grow properly and parents often ask for extraction ” Everyone grows tiger teeth, which are also called canines. It will always be there, whether it’s in the milk tooth or permanent tooth stage.” This is one of the typical characteristics of mammals. It is the sharp tooth between the incisors and molars of the upper and lower jaws of mammals or animals similar to mammals. “Looking like a cone, carnivores have very well-developed canines, while some herbivores do not have such teeth. The main use is to tear food. The clinical scientific name is ‘sharp teeth’.” Since tiger teeth are very hard and resistant to disease, and are not easily decayed, they are known as the “oldest” of teeth. However, for various reasons, many children’s tiger teeth are not normally aligned with other teeth and coexist peacefully, but are crowded to almost reveal the lips, very “unsightly”. The clinic found that many parents with small tiger teeth “can not help but” like to show outside the child to come to the door, open the door and asked to remove. “They often think that the tiger teeth are not important, and since they have been squeezed by the teeth on both sides of the body can not be accommodated, even after the extraction of the teeth gap is not large, especially when they hear that orthodontic correction takes a long time, they are more determined to pull the idea of teeth.” The child’s teeth from the milk teeth for permanent teeth stage, the tiger teeth replacement time is generally later than other teeth, if the milk cusp teeth due to trauma and other reasons fall out too early, it is vacant position may be the first to erupt “neighbors” crowded out. When the permanent cuspids come in late, they are found to be “occupied” and have to be embarrassingly squeezed out of the tooth row, which is conspicuously exposed when you open your mouth. For this reason, many parents want to use medical means to deal with the “eyesore” tiger teeth. The tiger teeth may cause caries after being removed arbitrarily. Clinically, we have seen small patients who were referred again after the tiger teeth were removed with unsatisfactory results, because the tiger teeth can affect the activity and beauty of the lips, so there will be unintended adverse consequences after it is removed. The tiger teeth on both sides of the human mouth bear the weight-bearing, biting and power-conducting role in the human mouth for a lifetime, and have its irreplaceable and unique role, because each organ of the human body has a practical use, and each tooth is an independent human organ that should be preserved as much as possible. In addition, random extraction may also lead to food residue in the gap, thus increasing the possibility of tooth caries. Because there is no orthodontic treatment after extraction, the remaining gap is easy to hide food residue, and the loss of this important tooth may also affect the chewing function of people. Another major disadvantage is the aesthetics. Because after the extraction of the tiger teeth, the corners of the face will collapse, the nasolabial folds deepen, the face fullness decreases, showing an old look, thus affecting the beauty of the whole face. Therefore, it is important to be cautious when extracting tiger teeth in order to maintain the long-term effect of facial plumpness. Orthodontic treatment is better than extraction Orthodontic treatment is relatively troublesome, but it can better preserve the oral function of the child, such as removing the teeth behind the tiger teeth, or grinding them down, and then pushing or pulling the tiger teeth to the normal position, which is better than extracting the tiger teeth. Children in the growth phase, the jawbone is still continuing to develop, as the jawbone grows, in the process of self-adjustment of the teeth, there is the possibility of the tiger teeth “back to the team”. The orthodontic treatment of tiger teeth at the age of 11 or 12 is the ideal time because it is at the early stage when the permanent teeth are replaced and the orthodontic clinical effect is the best, and it does not exclude the special cases that need to be treated at that time instead of waiting for this stage. Prevention is more important than treatment, for how to deal with children’s exposed tiger teeth, in addition to the need to consult a specialist, it is best to visit the dentist regularly during the period of tooth replacement for children, the time is six months or once a year is appropriate.
