Malocclusion is a developmental malformation of the teeth and jaws, which is often characterized by misalignment of teeth, abnormal occlusion (e.g. buck teeth, geodesic, etc.), and can be accompanied by developmental deformities of the jaws, open lips and teeth, and disproportionate facial features. The harm of malocclusion: misaligned teeth can increase the accumulation of plaque, impede oral cleaning, significantly increase the prevalence of dental caries, periodontal disease; abnormal occlusion will also affect chewing, pronunciation and other oral functions; in addition, it is very important that the malocclusion will damage the image of the human being, destroying the confidence of the human being, affecting the teenagers’ social life, especially in the future of the employment, choosing a spouse, and even affecting the human mental and psychological conditions and even future life path. Therefore, if our family members have misaligned teeth, we hope to pay attention to it to avoid the regret in orthodontics due to the limitation of our own condition. Especially teenagers need to pay more attention to, will directly affect the future character of the problem. At present, having a mouthful of neat and beautiful teeth has become a sign of health and self-confidence. The best time to correct malocclusion: common maxillofacial deformities in children can be divided into two categories: dental deformities and bony deformities. Dental malformations can be divided into general dental malformations and functional malformations. Different types of malformations have different optimal timing for orthodontic treatment. For general malocclusion, the best time for treatment is at the early stage of permanent dentition (i.e. around 12 or 13 years old). This is because this is the time when children have just finished replacing their teeth and are in the midst of their growth spurt. The optimal age for most fixed orthodontics is 12-16 years old, which some dentists refer to as the “golden age”. As for functional malformations, since they often appear in the period of replacement teeth, if the correction is delayed, they may develop into bony malformations, so their optimal period of correction should be in the period of replacement teeth (i.e., 6-12 years old). There are some children’s malocclusions that require early treatment (3-5 years old), such as “Baodi”, lip-biting, finger-sucking and other bad habits. Orthodontic treatment for adults is mainly to solve aesthetic problems, while improving the overall oral health conditions, and there is never a time limit to have an attractive, confident smile. However, orthodontic treatment for children is a lifelong concern, have you chosen the right time? How long does orthodontic treatment take? Generally, we expect orthodontic treatment to take about 2 years. However, treatment time varies from patient to patient, depending on the degree of malocclusion. As long as you work well with your orthodontist, follow up with your orthodontist on time, maintain healthy oral hygiene, and protect your braces from damage; then the orthodontic treatment time will be much shorter. Answers to parents’ concerns about orthodontic treatment: Many patients worry that orthodontic treatment will loosen their teeth and reduce their life span. In fact, orthodontic treatment is a kind of tooth movement within the physiological range, which will not significantly affect dental health. Temporary loosening of teeth during treatment is inevitable and normal, and will disappear naturally after treatment is completed. However, if you can not maintain good oral hygiene, will promote and aggravate gingivitis to periodontitis, secondary caries. Therefore, orthodontic treatment to maintain oral hygiene is essential, it affects the treatment effect and dental health, especially important for adults and patients who have suffered from periodontal disease, if oral hygiene maintenance is unfavorable, will inevitably cause irreversible effects on dental health. Some patients are also hesitant to have their teeth extracted because of orthodontic treatment, fearing that the reduced number of teeth will have any adverse effects or that the extraction gap will not be able to be closed. In fact, a lot of misalignment occurs because the jawbone cannot accommodate these existing teeth. Extracting teeth is to create a gap to align the teeth and adjust the occlusal relationship, in order to achieve aesthetic and functional perfection, which is conducive to oral health and will not leave any remaining gaps. Orthodontics is a long process, need to work closely with doctors and patients to achieve the ideal treatment results, patients in orthodontics before the start of the best to understand the necessary knowledge, clear their own treatment requirements, in the process of orthodontics need to pay enough patience and effort, to be able to adhere to the regular follow-up and good cooperation, orthodontics after the completion of the adherence to maintain the routine 1.5 years, some patients need to maintain a longer period of time or even lifelong. Doing these points, I believe that you will be able to have a mouthful of healthy and beautiful teeth, so as to have a more beautiful and confident life.
