If the bottom beak is growing out warped - due to not being ground naturally by the top one + also being mite affected - that should return to normal when the bird is better. The longer he is like this the more damage will occur.
When he's better - give him things to chew - like Sarah has with the Balsa wood pieces. My birds just discovered the Balsa wood - they had it on their cage for 4 months! Today they were fighting over it so much I had to put more pieces out.
We all hope that this works out for you & Tj.
If you can't find an avian Vet in your area try another clinic & ask if they have anyone with some bird experience.
I liked that link. They were very helpful.
