When we remove your braces, we will begin the retention phase of your treatment.  Retainers should be worn full time for the first six months.  Full time wear means day and night.  The following six months the retainers need to be worn at night.  After that, they need to be worn at least two to three nights per week long term.  Long term is as long as you want to keep your teeth straight!  It does take a commitment on your part to keep that new smile forever.
