How to determine whether your teeth need orthodontics? There is a very convenient way: please look at the mirror, take a closer look at their own teeth, if there are the following circumstances, we should pay attention to: 1, grimacing teeth, teeth, remember the movie “Wong Fei Hung” in the “tooth rubbing Sue”? He is a typical “blunt tooth boy” – this is called “deep coverage” in orthodontics, clinical manifestations of the patient’s front teeth protrude outward, the lips can not be naturally closed; upper jaw bone is obviously forward The upper jaw bone is obviously protruding forward or the lower jaw bone is short, and the chin appears to be shrunken behind the upper lip; the lip muscle is tense, and the face is “bird-shaped face” when viewed from the side. 2. “Geodontia” is the opposite of “bruxism”, and “geodontia” is the lower teeth, or “anticline”. In other words, the lower front teeth are wrapped around the outer head of the upper front teeth, while the upper front teeth should normally cover the lower front teeth. The more severe cases of anticlusion are caused by overgrowth of the lower jaw or undergrowth of the upper jaw. In this case, the majority of the front teeth are retrognathic, the jaw is more prominent, and the face has a sunken “crescent” shape when viewed from the side of the body. These individuals may have close or distant relatives in the family with similar conditions. In addition, some children’s retrusion becomes more pronounced as they grow and develop. Therefore, if you have a child who is teething, please pay extra attention to the lateral shape of the baby’s face. 3, double jaw protrusion These patients show that the upper and lower dental arches and front teeth are protruding forward, the upper and lower lips can not be closed naturally, forming “open lips and teeth”, side observation can be seen in the lower part of the obvious protrusion, some people also have a large or small gap between the upper front teeth. When smiling, the gums are often exposed too much, which is very unattractive. 4, bite too deep and bite on the bite too deep in the medical known as deep overlap, manifested as the upper front teeth too much cover the lower front teeth, serious lower teeth completely covered by the upper teeth in the inside, from the front can not see the lower front teeth. In severe cases, the lower teeth are completely covered by the upper teeth and the lower front teeth cannot be seen from the front. Those with obvious deformities will feel unable to use their front teeth to bite off food. 5. Gaps in the teeth There is no gap between the teeth in a normal row of teeth, one next to the other. However, some people have gaps in their teeth. Most of these malformations are due to the small size of the teeth and the arch that holds the teeth is too large. There are also people who suffer from periodontal disease for a long time, and gaps in the front teeth also appear in the abnormal bite state, and such gaps will become larger and larger, making the four incisors spread apart. 6, misalignment This is the most common type of malocclusion, mainly manifested as misalignment of teeth, inside out or even overlap. The reason is that the dental arch can accommodate the teeth alignment “place” is not enough, some teeth have to squeeze together. Of course, there are many other manifestations of oral malocclusion, the above list is only the common symptoms, you can compare and diagnose yourself through the above information, if you have any questions, please go to the hospital in a timely manner.
