You should wear your 3D Predict Aligners constantly, taking them off only when eating or brushing your teeth; approximately 22 hours each day. In order for a tooth to start moving, it needs to feel mild pressure for 2-3 days. Once the pressure is absent for 4 hours, tooth movement fully stops. If you stop wearing aligners for more than 4 hours, it will take several days for the tooth to start moving again. If you wear your aligners less than 22 hours a day, your teeth will be moving slower and you will not get the treatment result on time.
