Yes, for the best results, it's important to wear your clear aligners for at least 22 hours a day. You should only remove them when eating, brushing, or flossing. Clear aligners work by applying consistent, gentle pressure to your teeth, which gradually shifts them into the desired position. If you don't wear them for the recommended amount of time, you may not achieve the results you're looking for, and your treatment time may be longer than anticipated.
