How long should I wear my retainer after Invisalign treatment?

The teeth are most susceptible to relapse (or move back) within the first year or two of treatment.  However, teeth are always susceptible to shifting.  We've seen this with patients of any age, with or without wisdom teeth, whether they have had orthodontic treatment in the past or not.  For whatever reason, our teeth seem to shift as we age.  For that reason, a retainer should be worn every night for as long as you want to maintain straight teeth.
