It depends on how old they are and how long it has been since you last had any followup or any other adjustments. Your teeth are moving all the time, they shift and move, twisting, etc. in the mouth as you age and change. So, an old retainer may try to move, or apply pressure to your teeth, the chances of it succesfully straightening you teeth are not very good. But if you check with you Dentist, you may be able to use that old retainer for some follow up work, once Your Dr.'s had a chance to update your adjustments.
I am also wondering about the intent of the questioner. How do you know that your teeth are not straight? Is this the first time you noticed that your teeth are not straight? How long has it been since you wore your retainers last?
