Clear aligners  are trays that are worn over the teeth to slowly change and reposition the teeth. They are comfortable and almost unnoticeable when wearing. They are worn all the time except removed for eating and drinking

Each Aligner moves the teeth closer to final alignment. You will go through a "series" of  trays during your orthodontic treatment. Every two weeks, you wear the next tray in the series. The number of trays will vary, depending upon the severity of your misalignment.
