How long does orthodontic correction need to be re-examined?

Dental experts say that orthodontic treatment needs to be repeated every three weeks on average. "Orthodontic" can be compared to a difficult project, the object is the body's tissues, and the tissues for the corrective force of the response, most of the expected, but sometimes there are unavoidable contingencies. These emergencies are especially likely to occur at the beginning and near the end of orthodontic treatment. In order to avoid surprises or delays, the orthodontist may make more intensive appointments at the beginning and end. Under normal circumstances, the average patient will be asked to return for adjustments in about three weeks, based on the following rationale: studies have shown that once a tooth is subjected to an external force, the surrounding tissues will quickly undergo a series of changes within a few days, and it is best to allow some time for respite and recovery afterward, and three weeks falls into a benign cycle. Doctors generally expect patients to return every two weeks because they are concerned about delays that may affect the final outcome of orthodontic treatment. In addition, the size of adjustments, the individual variability of the patient, or even the patient's cooperation in wearing orthodontic appliances, oral hygiene habits, and so on, all affect the length of the interval between appointments.
