Because each patient is unique, the Invisalign process is tailored to meet their individual needs. Generally, it is recommended that patients use the device 12 to 22 hours a day, every day, for three to six months. After this period, most people can stop wearing the retainer during the day and only use it at night for 12 months after Invisalign treatment has ended. A fixed retainer is a thin wire that connects the six front teeth from a canine tooth to a canine tooth.
It is important to wear the last Invisalign tray until the retainers arrive to keep your teeth from moving. If your removable retainer breaks or looks worse from wear and tear, contact an Invisalign dentist right away. It is normal for your teeth to move slightly after you have your Invisalign braces removed or after you stop wearing Invisalign. This is due to daily wear and tear on the teeth when biting, chewing, swallowing and talking.
If the treatment included teeth further back, there's still a chance that they might move, so a clear retainer might be better suited to keeping all of your teeth straight.
