If you've ever dealt with metal or ceramic braces before, you know that food easily gets stuck in them and it's harder to keep your mouth feeling fresh and clean. Since invisible braces can be removed, you avoid this altogether. However, some people notice that their invisible braces start to get a film over them after a couple of days and need to be cleaned. Your dentist will direct you in the best way to care for your exact type of invisible braces, but a great way to keep them clean is to brush your teeth well after you eat and remove your invisible braces for meals and even when you drink anything besides water. Aside from this, invisible braces can be brushed with a soft-bristle toothbrush and rinsed well. Some brands of invisible braces offer a cleaning solution that you can use to soak your trays every few days.
