Will retainers keep my teeth from moving
Unfortunately, just because your teeth are straight when you are young doesn't mean they can't move as you get older.
So, yes, retainers will keep things were they are...but since you will need to wear them forever at night, ask yourself if you are happy with the current alignment...if you need to wear the retainers anyway, maybe you want to get your teeth ideal before you make retainers.
