The first-year students of a school found it strange that two students in the class, Mao Mao and Fang Fang, had thin wire-like devices installed on their teeth. It turns out that one of them has uneven teeth alignment, and the other one is receiving orthodontic treatment from a dentist because their teeth are “enveloped in the sky”. 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, white teeth. This is actually not true. In the process of tooth eruption, under the influence of various factors, there is a possibility of misalignment or abnormal position between the upper and lower jaws. These phenomena are collectively referred to as malocclusion in dentistry. What are the dangers of malocclusion? There are three broad categories of malocclusion. The first category is misalignment, such as one or two teeth being displaced or twisted in the dental arch, such as “tiger teeth”. The second category is the uncoordinated shape of the dental arch and tooth arrangement, such as the dental 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 speech 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 Some malocclusions are related to bad habits. For example, some children are three or four years old and still can’t sleep without a pacifier; some children like to use their tongues to push their teeth outward or chew on their nails and pencils when they have nothing to do; some children like to chew food on one side, etc. How to carry out orthodontic treatment? Correcting the above-mentioned bad habits can achieve the purpose of correcting malocclusion in 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 treatment age for orthodontic treatment is 12 to 18 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 appliances are widely used in clinical practice and are 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.
