Hi Animesh!
To begin with, if you feel your occlusion is not stable, please let your Orthodontist know about it. The Orthodontist can re-assess or explain you the status of the occlusion.
Secondly, it is important to know that the Joint, muscles, bone and teeth work harmoniously together for functions like eating, chewing, speaking etc. With changes in any one, the others will get affected and they will take some time to get adjusted to new positions.
The lower jaw will not move beyond the achieved stability point with the occlusion and the joint.
Next Steps
Raise your concern to the Orthodontist about the unstable occlusion. Be patient and start with a semi-solid diet initially. do not jump to eating extremely hard food.
The idea is to give as less load to the joint and muscles as possible initially.
Health Tips
Wish you a speedy recovery!
P.S. : Please talk and laugh as much as you wish! It's nowhere related to your jaws or the joint.
