Caring for Invisalign Aligners
The Invisalign system is designed so that the trays can be removed for easy cleaning. So please don't neglect to do this. You'll need to brush your teeth after every meal or snack so that food and plaque do not get trapped in the aligners, which could promote tooth decay and gum disease. Your aligners, too, will have to be cleaned regularly; you can do this by brushing them and then rinsing them with lukewarm water.
Also, please keep in mind that while wearing clear aligners is very different from wearing braces, the importance of retaining your post-treatment results is the same. You'll want to be sure to wear your retainer(s) exactly as prescribed after your treatment is completed to protect your investment in a beautiful new smile.
