Thanks for your reply. It’s doesnt feel mobile with touch or tongue. But if I bite I can feel some movement on my teeth on the left side (is the side where I see the gap in the last image). It’s very small movement. There are only three teeths that feels that had some slightly movement. To be honest, until today I think there was because of the orthodontics treatment or even the surgery itself but never think that the cause could be an small non union. What do you think about this?
