I just got my braces off on Tuesday, But I feel like they are shifting and becoming crooked?!!?

Retainers are meant to hold your teeth in the same spot. So putting your retainers in move your teeth back to its original straight spot if they have moved. After the three days if your still worried there moving and your teeth look different just contact your orthodontist and where your retainers 24/7 if your not comfortable only wearing them at night.
