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.
Retainers: Retainers are used to keep teeth in place once braces are removed. It takes time for your teeth to settle into their new position. By wearing a retainer, you can prevent your teeth from shifting. Some retainers may be removable. Others are fixed -- bonded behind your teeth.
