Retainers are for slight over lapped teeth, or medium size overbites/ underbite!. Retainers can be used for the outside on your teeth or the inside behind your teeth.
I'm not sure if you can. Why would you want a fake retainer? Retainers are used to straighten teeth.
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?
There are various types of retainers. There are ones that attach to your teeth glued. And there are types that go on the outsides of your teeth which are removable at any time.
