Invisalign aligners are easily removed, so eat your normal foods without restrictions. More importantly, this allows you to easily brush and floss your teeth after every meal for proper dental health care. When you clean your teeth, you should also sanitize your aligners, either with a special Invisalign kit or simply by brushing them and rinsing with lukewarm water.
Aligners should be removed when participating in contact sports. They are not mouth guards! When you finish playing sports, put your Invisalign aligners back in.
Invisalign is removable, but for the system to be effective, you must wear the aligners for 20 to 22 hours every day. If you do not meet this daily requirement, you will likely retard your treatment progress.
New sets of aligners are delivered approximately every two weeks. Use these in place of the previous set of aligners. Keep the old set, however, in case you lose your current set. If you follow this procedure, you will have a similar aligner ready to use until you receive a replacement.
