Your aligner is designed to be worn 22 hours a day, allowing you to take it off for meals or important social occasions. Yet even when you're wearing it, it's pretty hard for anyone else to tell it's there — a big difference from metal braces! Plus, it offers other advantages that aren't so easy to see.
One benefit of aligners over traditional braces is that they make your teeth easier to clean. Because they're removable, there's nothing to keep you from brushing and flossing everywhere in your mouth, just as you would without appliances. But brushing and flossing can be much harder to do around the brackets and wires of braces — and oral hygiene often suffers.
Some people also suffer irritation to the cheeks and gums from the metal parts of braces. Fortunately, the plastic of an aligner rarely causes that kind of problem. Plus, you won't have to rush into the dental office to quickly fix a protruding wire or reattach a broken bracket. You won't have to watch what you eat, either, because you'll simply remove the aligner at mealtimes.
