I have one upper anterior crossbite and one lower crossbite, teeth are crowded,no overbite or underbite ,just those two teeths .it's not much noticeable,i need to fix these two teeths as they might get me rejected in army medicals,i will get 42 days after rejection to fix this issue,is it possible,when i go again to the hospital,they should be in proper place,though after that i can wear braces etc for another 4-5 month till joining.
