how long for teeth to shift after retainers
Relapse means that the teeth can take up to one year or more to stabilize after treatment. If you had gaps between your teeth before treatment, the retention period will be longer. Usually, retainers are worn for as long a time as you have had your braces.
For how long do I need to wear retainers? It takes time for the bone and all the tissues around your teeth to reorganise and therefore it is necessary to use retainers until your bite stabilises. In the first month after the braces are removed, the risk of relapse is very high.
