Brush your teeth every day, how can you still have disease? Some children and teenagers, and even some parents, think that as long as they keep brushing their teeth, they will have a healthy, whitened teeth. In fact, it is not. Director Wang of Shanghai Renai Hospital pointed out that, in the process of tooth eruption, under the influence of various factors, there is a possibility that the teeth are not aligned or the position between the upper and lower jaws is abnormal. These phenomena are collectively known as malocclusion in dentistry. What are the dangers of malocclusion? There are three types of malocclusion. One type is misalignment, such as one or two teeth that are displaced or twisted in the dental arch, such as “teeth”. The second category is the incongruity of the arch form and tooth arrangement, such as the arch is too wide or too narrow, and the teeth are sparse or crowded. The third category is the abnormal occlusal relationship between the upper and lower teeth, such as the recession of the front teeth, commonly known as “encephalitis”. Malocclusion not only affects aesthetics, but also affects chewing, which is not conducive to digestion, and can cause some psychological stress to patients, as some malocclusions affect pronunciation and language communication. Therefore, parents should take their children to the hospital as soon as possible for treatment if they have malocclusion. Bad habits can cause malocclusion Director Deng said that some malocclusion is related to bad habits. For example, some children are three or four years old and still can’t sleep without a pacifier; some children love to use their tongues to push their teeth outward or chew on their nails and pencil heads; some children like to chew food on one side and so on. How to carry out orthodontic treatment Correcting the above-mentioned bad habits can achieve the purpose of correcting the malocclusion of children under 5 years old. Some malocclusions caused by poor muscle movement can be treated with muscle function training under the guidance of a doctor. However, if the child is already older and the malocclusion is already very obvious, orthodontic treatment should be performed. The best age for orthodontic treatment is from 10 to 14 years old, during which the treatment is short and effective. The older you are, the longer orthodontic treatment takes, the more difficult it is to treat, and in some cases, surgery is required. There are two main methods of treatment. One method is to use movable or fixed orthodontic appliances for orthodontic treatment. Mao and Fang are wearing fixed orthodontic appliances. The fixed orthodontic appliance that is widely used in the clinic is more effective. Another method is surgical treatment. For adult patients with jaw deformities that seriously affect their facial appearance, surgical treatment is required. No matter what kind of oral disease treatment, be sure to take the child to the regular dental hospital or a certain scale of general hospital stomatology, never to the poor conditions, low medical level of dental clinics, especially can not find those unlicensed street doctors.
