This is called orthodontic relapse. It is when the teeth begin to move back to their old spaces after orthodontic treatment ends. For this reason, our Invisalign provider recommends retainers. Invisalign retainers look and fit just like the aligners worn during treatment. However, they do not work to shift the teeth, but rather keep them in place.
Our dentist will likely recommend you wear your Invisalign retainer 24/7 at first, so the teeth can get used to their new positions. Then, you might be able to wear them only at night. Any orthodontic relapse that occurs may require another treatment to correct. It is therefore important that an Invisalign retainer is worn as instructed.
Our dentist will ensure you are clear on the usage and purpose of your retainer. You can get more information about it on our website.
