There is no specific time for archwire replacement, it is based on the movement of the teeth in our mouth. If the patient is younger and the teeth are moving faster, the entire procedure becomes easier and the archwire is replaced step by step according to the model. If the patient is older and has more difficulty moving, the archwires will be replaced more slowly. However, orthodontic treatment requires a monthly follow-up visit, during which the orthodontist will see every change in the alignment of your teeth. The orthodontist will see each change in the alignment of your teeth, and then adjust the change in strength according to the individual case. The archwire will not necessarily be replaced, but there may be a certain amount of force added or subtracted in a localized position, so the patient will still need to go back for monthly follow-ups.
