Cases of Relapse (Teeth Shifting Back) After Invisalign?

But the beauty of Invisalign is that you get clear retainers afterwards that look and feel just the Invisalign trays, so patients are more likely to wear them as opposed to the old plastic and wire ugly retainers of yesteryear.
All teeth will shift after teeth straightening if not held in place or a couple years. I always tell my patients that retainers need to be worn forever at nite if they want to keep their straight teeth. I still wear my retainer and I had braces 20 years ago.

After you complete your Invisalign Treatment, you will wear retainers at night (still clear/invisible, comfortable Invisalign trays) to prevent your teeth from shifting back.   You get new retainers 2 or 3 times per year and the new retainers keep your teeth in the ideal position.

Invisalign is perfect solution for relapse of braces. Invisalign should resolve slight overcrowding and slight overjet easily. However, in general, any kind of tooth movement needs to have retention program for good prognosis by using retainers for life.
