Not only are the aligners virtually invisible, they are removable, so you can eat and drink what you want while in treatment. Plus, brushing and flossing are no problem. They are also more comfortable than traditional braces, with no metal or wires, which also usually means you spend less time in your doctor's office getting adjustments. Invisalign treatment also allows you to view your own virtual treatment plan when you start so you can see how your straight teeth will look when your treatment is complete.
