Our Pastel Has an Overbite

We purchased an early 2010 male Pastel from a friend who we have bought MANY snakes from and we trust completely. I never asked him where he got our boy from (I can if it matters) but he said that the snake came with a short bottom jaw. He says its from bad incubation, and that it will grow out soon. He is a wonderful eater topping at 505 grams. He hasn't eaten for us just because he was stressed from the move, then we had an accident with him where he got stuck on a bar and was smashed in our new tank and broken a large number of ribs. Don't worry that bar was quickly cut off. He is ok, moving everything and just has a few scraps. We are just giving him a rest and healing him up. He's feeding on sm f/t rats. I guess the reason Im posting all this is Im wondering if he will restore that bottom jaw, and does it affect his value if we were to sell him. I have a pic of just his colors, not his jaw. Ill get one up soon.
