We get this question a lot from our patients. Basically, if we move or align your teeth expect to wear a retainer. It does not matter what kind of appliance (Invisalign, braces or expander etc) is used to move your teeth. So, yes even with Invisalign treatment we are recommending our patients to wear their retainers as prescribed. In some cases it will be for shorter time and then just at night and in others it will be for a longer term full time and then to just at night. Your mileage will vary depending on what type of bite and crowding problems you started with, its as simple as that. So, just because your cousin, friend or Aunt only wore their retainer for 3 months does not mean you will. You and your smile is unique and your Rx will be different just for YOU. Please feel free to call our office for a complimentary orthodontic consultation and see how we can help you.
