Clear aligners as an adult: what to actually expect

The most common adult concern isn't the trays, it's the timeline — most cases run somewhere between six and eighteen months depending on how much movement is needed, with check-ins roughly every six to eight weeks.

Comfort-wise, expect mild pressure for a day or two after switching to a new tray in a series, not ongoing pain. Speech adjusts within a few days for most people, and they're removable for eating, so there's no food off-limits.

The part that trips people up most is wear time — these only work if they're in for 20-22 hours a day, so it's worth being honest with yourself about your daily routine before starting a plan.
