Once the teeth are done moving and have made their way to their proper positions, Invisalign attachments can be removed. For optimal results, they should not be removed before the orthodontic treatment has been completed.
The number of attachments varies depending on the treatment and the specifics of your case. Some Invisalign patients do not require attachments, and others require up to 20. Most require somewhere in between. Your orthodontist will make the ultimate decision depending on your case and diagnosis.
