In the process of correction, the teeth are loose. Please rest assured that this is normal. Think about it. Teeth are fixed. Assuming they are not loose, how do they move? You can't move unless it's loose.

Under the action of our weak force, the force must be controlled within 150g (g), and the teeth will give the periodontal ligament a squeezing force, which will be transmitted to the alveolar bone through the periodontal ligament. Alveolar bone has the characteristics of force absorption and traction proliferation, so that teeth will move in the direction of absorption. In this way, the teeth are loose, the correction is completely in place, and the alveolar bone around the teeth is slowly growing out. Before the braces are removed, the teeth are still stressed and will not be fixed. Until the braces are removed and the retainer is put on, the teeth are not affected by external forces and begin to stabilize gradually.
