The cost of Invisalign will vary for each patient based on the severity of the orthodontic disorders, the number of aligner trays required, and the level of coverage the dental insurance provides. The cost of Invisalign might be as low as a few thousand dollars in more straightforward circumstances; however, serious conditions might cost upward of $8,000 or even more. Since Invisalign falls under the category of orthodontic treatment, some insurance policies may fully or partly cover the cost.
