Lost my retainer, ortho doesn't have my old molds. If I buy a new one, will my teeth stay crooked as they are now?

Can retainers move teeth?
In general retainers are used to preserve the position of the teeth so as to prevent shifting. However, sometimes we can adjust retainers to achieve small improvements such as closing small spaces or moving a tooth back into alignment that has moved forward/backward. Usually turning or rotating a tooth is very difficult for a retainer alone to correct.
Keep in mind, in order to achieve any type of movement, the retainer will have to be worn on a full-time basis and then can be switched to part-time (i.e. while sleeping) once the correction has been achieved.
Hope that helps!
