Hi.
If your tooth is already cut nothing much can be done,the crown will be made according to the size of ur current tooth.
In case your permanent crown comes out repeatedly after fixing , then composite build up can be done to increase the size of the crown and later other procedures will be followed.
Don't worry it will not be visible and replaced by zr Crown and if it's not troubling you after fixing then no issues.
Hope ur question is answered and it was helpful.

*Avoid biting from front teeth after fixing the permanent crown.
