As food becomes finer and softer, modern jaws lack the stimulation of hard and coarse foods and tend to degenerate, resulting in an increasing prevalence of malocclusion. Problems such as crowded teeth, whistling teeth/buck teeth, enameled teeth/backbite, crooked jaws, incisor gaps, etc. can be seen everywhere, affecting personal image and health (including mental health) at all times. In fact, these problems can be solved through orthodontic orthodontic methods, but people have misconceptions about orthodontic orthodontics, to blackmail, delay orthodontic timing, and even lifelong damage. Myth 1: Tooth extraction Not all patients need to be extracted, orthodontists will assess the degree of malformation of each patient, so as to judge whether the need for tooth extraction. As mentioned earlier, modern jawbones are relatively shrunken due to the lack of stimulation from coarse and hard foods, but the number and size of teeth are no different from those of previous generations, and the jawbone is not large enough to accommodate so many teeth, resulting in crowding and even more severe malocclusion. In order to match the teeth to the jawbone, it is often necessary to remove the less functional teeth to achieve the best functional and aesthetic results. Myth #2 Loose teeth 100% of the teeth will become loose during orthodontic treatment, because during this period the teeth are moved in the bone by the force of the braces, the bone around the roots is absorbed and loosened, and the teeth exhibit a certain degree of mobility. However, there is no need to worry about this, as the loosening of the teeth is within the physiological range and is only temporary. When the braces are removed, the teeth will no longer be under stress and will naturally re-stabilize. It is true that orthodontics is not an easy task, but it is not that outrageous. Generally, when you first get braces, your teeth will be “stressed” by the braces for the first time from a relaxed state. The first week of teeth will feel sore and weak, this period will choose to eat softer food, and after this stage, adapt to the orthodontic force, eating is not too much restriction. The problem of braces grinding mouth more or less still exists, the use of orthodontic protection wax effect is very obvious. Myth 4 Too old Although most orthodontic orthodontic treatment is aimed at children and adolescents, there is no age limit for orthodontic treatment for adults who need it. As long as adults usually pay attention to the maintenance of oral hygiene, periodontal condition is better, as well as orthodontics, but the speed of orthodontics is slower than children and adolescents, need a little more persistence. Myth #5 Orthodontic timing For most patients the best time to get orthodontic treatment is just after tooth replacement (11-14 year old girls / 13-16 year old boys). Some conditions such as diastema/backbite, crooked jaw, small jaw, large incisor gaps, abnormal number of teeth, etc., it is too late to wait until the patient has finished replacing teeth before orthodontic treatment. These conditions should be seen as soon as they are detected and early intervention should be made to avoid aggravation of the malformation. As parents may not be able to distinguish the problem of malocclusion in their children, it is recommended that: when you notice abnormalities in your child’s teeth, you may want to come to the orthodontics department for an examination and listen to the doctor’s opinion so as not to delay the treatment.
