Clear braces are permanently affixed to your teeth until the treatment is finalized. Invisalign braces can be removed when you eat and for dental hygiene. Invisalign requires your own self-discipline to ensure that they remain in your mouth for 20-22 hours a day. If you commit to this, it can work very well. If you don't, the treatment time can become longer. If the Invisalign braces aren’t kept in for the recommended time, you may need to have them "refitted,” which creates an additional cost. Clear braces tend to be a better option for younger people because they don’t have to remember to put them back in.   Invisalign aligners can be removed to clean your teeth, so dental care is easier with Invisalign than with clear braces. Clear braces require a more stringent cleaning routine. Clear braces also have some food restrictions. You will need to avoid certain types of foods, and popcorn is off-limits. Invisalign has no food restrictions since you remove them before you eat.   Invisalign allows you to eat anything you want, but you shouldn’t drink anything but water when you have them in. Sugars and acids can get under the aligners, causing bacteria growth and bleeding. Invisalign aligners frequently get thrown out, accidentally, since they are removed when eating. This can add an extra expense. Invisalign aligners will require cleaning each time you take them out to eat.   Invisalign is less irritating than clear or traditional braces. They are usually more expensive than clear braces.
