Misconception 1: irregular teeth are not a big deal. The attitude of not understanding and taking the disease lightly often delays the best treatment opportunity. The harm of malocclusion is mainly reflected in the function, health and psychological aspects, affecting the normal function of children’s oral cavity, such as chewing function, pronunciation function, breathing function; affecting the beauty of the face; affecting the health of periodontal tissues and oral hygiene, causing caries (worm teeth), tartar (tartar), gingivitis (gum bleeding), etc.; damage to facial image, affecting children’s psychological health, and in serious cases, affecting their assessment of their future self and expectations. Myth 2: Aligning the incisors is orthodontic treatment. Orthodontic treatment is not only to align the incisors, but also to establish a stable bite relationship between the upper and lower teeth, especially the large teeth at the back, and to restore good oral chewing function. An important criterion to judge the merit of orthodontic treatment is the good or bad bite of the back teeth. Myth 3: Only 12 years old can be orthodontic This concept is actually one-sided, and even harmful, the best orthodontic period is 8 to 14 years old. With the continuous development of orthodontic technology, there is no limit to the age of orthodontics, but there is an optimal orthodontic period. Orthodontics in the best orthodontic period, the time required will be shorter, and the cost required will be lower. Misconception 4: orthodontic teeth can be orthodontic teeth without extractions “the best not to extract teeth” is the principle of orthodontic program design, but it does not mean: “not to extract teeth can be orthodontic teeth”. Extraction is very common in orthodontic treatment, about 60% of patients need to be extracted, and even without orthodontic treatment, most people with poorly positioned wisdom teeth, affecting the periodontal and front teeth health should also be extracted. Extraction orthodontics has withstood the test of clinical practice in the history of orthodontic development. Some diseases such as severe crowding and protrusion of teeth must be corrected by tooth extraction. If the teeth are not extracted, not only will the deformity not be corrected, but some of the teeth that have been painstakingly crowded will soon return to their original deformed appearance. When teeth are extracted there are gaps, these gaps are usually not necessary to set teeth and most of the gaps will be completely closed after the orthodontic treatment is completed. The hesitation of the patient or parents to extract teeth often interferes with the doctor’s determination of the orthodontic plan. In some cases, even though orthodontic treatment is barely necessary without extractions, the end result is very unsatisfactory, and in some cases treatment is not even possible without extractions. Myth 5: Just find a small clinic Orthodontic treatment requires an orthodontic professional to make a professional decision after a thorough examination and analysis, so it is very important to choose a professional hospital and doctor. Experienced doctors will pay close attention to the dental health and bite relationship during the orthodontic treatment process, to ensure the function and health of the teeth under the premise of completing the aesthetic restoration of the teeth. In the choice of orthodontic materials, it is recommended to try to choose brands and products of reliable quality to minimize the impact of orthodontic appliances on children. Myth 6: Orthodontics is prone to tooth loss Some parents worry that orthodontics will cause loose teeth in old age, and even early tooth loss, this view is not scientific. Orthodontic treatment is to induce tooth movement through light orthodontic force, a slow biological modification process, the bone on one side of the moved tooth resorption, the other side of the new bone reconstruction, and finally make the teeth move to the normal position. Orthodontic treatment is never traumatic to the teeth or periodontal tissues. And orthodontics has a history of more than 100 years, time has proved that this technology is quite mature. Myth 7: The shorter the orthodontic time the better The amount of tooth movement is limited, generally 1.5 mm per month, moving too fast will lead to loose teeth. Depending on the severity, the course of treatment is not the same, generally one to two years or so, some doctors or patients to shorten the time, do not follow the scientific rules, impose too much orthodontic force, the results of the patient’s pain is heavier, too much tooth loosening, serious cases will cause patients orthodontic tooth loss.
