You wouldn’t be alone if you weren’t wearing your Invisalign for the requisite 22 hours per day. Even if you wear them for that time, your two-hour break might yield still-crooked teeth after your treatments.
Consider using a free app like TrayMinder to record your smile journey. It’ll calculate the time you’re not wearing Invisalign and remind you to set limits for going trayless.
Another option is using the “smart” retainer case called nCase. It has a mobile app that simplifies tracking your wear time.
