1, oral hygiene orthodontic process, the gums and alveolar bone are rebuilt with the movement of teeth, if you do not pay attention to oral hygiene will lead to gum inflammation, hyperplasia, alveolar bone reduction, affecting the effect of orthodontic treatment, serious cases will lead to orthodontic treatment suspended. 2, the degree of pain orthodontics is to rely on the external force applied to the braces to drive the teeth to move, the alveolar bone is absorbed and rebuilt process. Tooth movement causes the periodontal membrane connecting teeth and alveolar bone to be squeezed and stretched. The greater the force applied to the aligner, the faster the teeth move, the greater the compression and stretching of the periodontium, and the more painful we feel; if the force applied to the aligner is too great, it will damage the periodontal tissue and lead to tooth loss, which will also affect the patient’s daily diet. The pain generated by the orthodontic process is generally tolerated by patients, and the degree of pain with the increase in the wearing time of the braces is becoming less and less, so once the orthodontic process of pain abnormalities, please see a doctor immediately. 3, the degree of tooth loosening teeth under normal circumstances there is a certain amount of physiological loosening to relieve the pressure of chewing, in the orthodontic teeth loosening will be moderately increased, but if found too much loosening, need to adjust the aligner, suspend the force, let it recover for a period of time and then continue to add force. 4, orthodontic appliance damage treatment Wearing orthodontic appliance during the orthodontic appliance, if the orthodontic appliance damage should be promptly contacted orthodontist for treatment, do not handle their own to avoid damage to teeth and oral soft tissue. 5, regular visits During the orthodontic period, the orthodontist needs to add force according to the movement of the teeth, adjust the arch wire at the right time to ensure that the teeth move towards the intended position to achieve the purpose of orthodontics, so follow the doctor’s instructions and follow up on time. 6, pay attention to diet Wearing braces is not easy to clean, so try not to eat too sticky, sugary food, drinks to avoid causing tooth decay; at the same time, avoid chewing hard food to avoid causing brackets, rings, archwires and other accessories to fall off and affect the normal orthodontic process.
