It’s your last scheduled day of wearing your Invisalign clear aligners so you jump out of bed, ready to show off your new smile to the orthodontist. After making it to the office, the treatment proved to be a success and you hand your aligners back and head on your way. However, the doctor stops you from leaving. “Did you forget? We need to give you your retainer.” At first you’re puzzled, then you remember back to the first day of treatment. Your Polaris orthodontist mentioned you’d need a retainer after you finished wearing your aligners.
