Orthodontic treatment..

[msconfused]

Hey, my nephew is undergoing orthodontic treatment in cosmetic dentistry in Milton. He has put on conventional braces, so pain is common. But the thing is he isn't having anything ever since then. He is fed up of having juice and liquid food.
So could you please suggest some good food for him to eat without pain.
Please suggest some delicious food recipes for him to try too!
Many thanks.
