How Many Hours Should You Wear Invisalign Per Day?
Just started your Invisalign treatment or considering it? This is THE question every patient asks before committing.
The answer is clear: 22 hours per day minimum.
But why this specific duration? And what happens if you don’t follow it?
Clinical experience proves it: this rule makes all the difference between successful treatment and a journey full of setbacks. Here’s everything you need to know.
Why 22 Hours Per Day?
The Science Behind This Duration
Your teeth move through constant, gentle pressure applied by the aligners.
This pressure must be maintained without interruption to:
- Prevent teeth from “returning” to their initial position
- Respect the programmed 3D treatment plan
- Achieve results within the predicted timeframe
Less Than 20 Hours = Compromised Treatment
Diamond Provider tracking data proves it:
- Less than 20h: 2-3 month treatment delay
- 18h or less: loss of tooth movement precision
- Irregular wear: permanent discomfort when changing aligners
The 2 Hours of "Freedom": How to Use Them
Authorized Times to Remove Invisalign

One occasional day, no. But let us know. Repeated forgetting compromises your treatment and investment.
Absolutely! Nighttime represents 8 continuous hours of orthodontic treatment. It’s actually the most important time.
