Tiger tooth, the scientific name of permanent tooth, protrudes outward because of its dislocation growth on the labial side of dental arch, forming incisors shaped like tigers. Therefore, there are two reasons for the emergence of tiger teeth: first, the fangs erupted late, and the first pair of fangs around the lateral incisors and fangs erupted only after they erupted, and their "territory" was occupied and they had to be displaced to form tiger teeth; Secondly, deciduous teeth fall off prematurely. If the deciduous teeth have fallen off and the "subsequent" permanent teeth have not yet grown out, the adjacent permanent teeth have already grown out. When it is under the pressure of chewing, it has to grow from a higher position on the lip side, thus forming tiger teeth.
Children have tiger teeth, and parents always think that it will affect their appearance and advocate pulling them out. In fact, the role of tiger teeth is great. The root of tiger tooth is the longest tooth in the whole mouth, and it grows firmly in the jaw. It lives longer than all teeth. Because of its large and sharp crown, it is mainly used to chop up food when eating. The crown is hard, smooth on all sides and has good self-cleaning effect. It is the lowest incidence of dental caries or periodontal disease in the whole oral cavity. After other teeth fall off in old age, tiger teeth are often used to fix dentures because they are strong and strong. If they are pulled out, they will lose a very useful foundation, which will bring inconvenience to the future oral cavity repair.
Not only that, tiger teeth also play an important role in maintaining face shape. Because it is located at the corner of the dental arch, it can not only maintain the normal shape of the dental arch, but also support the squab to make the lips look full, which plays an important role in fullness and cheeks. If this tiger tooth is pulled out, the upper lip and mouth corner will lose their support, and the shape of the mouth will change, which will promote the original angle and three-dimensional sense. The mouth corner often collapses and the lower part is shriveled, showing an "old woman's mouth" and giving people a feeling of aging and listlessness.
If the child has tiger teeth, don't pull them out easily, and go to the orthodontics department of the hospital in time. Under normal circumstances, the tiger teeth that grew before 16 years old can continue to grow, the dentition can be adjusted by itself, and the fangs can be restored to their original state. At ordinary times, children should be educated to press tiger teeth with their washed right thumb in the direction of alveolar bone, 3 -5 times a day, each time 10 minute, which can achieve good results. If 16 years old still has tiger teeth, please ask the doctor to "push" or "push" it into the dental arch so that it can "return to the team" and return to normal dentition.
