How Many Hours a Day Do I Need to Wear Invisalign?

Hi-  I would recommend that you wear your invisalign trays about 21-22 hours a day and then switch them every 2 weeks. If you are wearing them only 18 hours a day, then I would recommend switching aligner trays every 2 1/2 weeks.

It is important to talk with your invisalign doctor and be honest with your amount of wear time so that you and your doctor can come up with an invisalign schedule so that your aligners track well and your teeth progress nicely.

Invisalign trays are made to be worn 22 hours/day for 2 weeks/tray.   An occasional missed hour here and there can be tacked on with an extra day added at the end of the two weeks.  But wearing the trays less than recommended can negatively affect your result. For Invisalign or any orthodontic procedure to work teeth need to have constant, gradual pressure.  When the trays are left out more that two hours, the teeth will tighten up, and then when you put your tray back in, it takes quite a few hours just to reloosen your teeth so they move.  So you have lost the time when your tray was out plus the time to reloosen the teeth each time.  Invisalign is a commitment of finances and time.  The result will be worth your investment.  Make sure you are honest with your dentist about how long you've been wearing your trays so they can recommend the best course forward for you for a great result. Best Wishes!

Hi,


You need to wear Invisalign 22 hours out of 24 a day.
Only when you brush and floss your teeth and when you eat you can take the aligners off.


Sincerely,
Dr. Barba
