Clear aligners are a modern orthodontic option that gently shift teeth into better positions using a series of nearly invisible, removable trays. Unlike traditional braces, they don't involve brackets or wires, making them more discreet—though they do require consistent wear for about 22 hours a day to be effective. They're popular among adults who want to fix crowding or gaps without looking like a teenager in braces.
