How do orthodontics now when to take ur braces out?

we would know and you would see the changes.





usually we have a reference, that is the old picture and old model of your teeth, with there we compare, then we compare your teeth to the standard set of teeth, if your teeth falls on th standard set then we could take off the braces.





however before doing so, the repositioned teeth should be evaluated through xray if they had already integrated with the bones of the alveolar socket via periodontium. In simplier word we should asses with the x ray if the teeth that is in proper position had a well developed bone to support it when the brakets are removed.
