Three days ago I started using an authentic Myobrace A2 large from AliExpress, it is very intense, before I used a Myobrace K2 medium and it is very easy on my mouth. At night I haven't used the A2 yet but during the day it is already very intense. Even though I have a narrow palate, I have only one tooth that is out of alignment, a central incisor in the lower arch, I noticed that it has more mobility than the other teeth and also the other neighboring incisors, now no I don't know if the mobility was like this before but this tooth is in constant movement, when I remove the A2 after a while the incisor goes back to how it was before about 2-5 hours. However, I noticed that it aligns the teeth well, but I'm afraid that this constant movement could increase the mobility, I don't know, maybe it's part of the process and that tooth is in a point that is already out of alignment and therefore more mobile... I don't know, however I noticed that this crooked incisor is also a little more extruded than its neighbors. I don't have any kind of recession. I would be grateful for any advice or considerations.
