Invisalign WORTH IT RATING* DETAILS. *Worth It ratings only factor in Worth It and Not worth it ratings. Invisalign aligners are used to straighten crooked or crowded teeth, as well as close gaps and adjust overbites. The treatment involves wearing clear, plastic trays that are custom-designed for your mouth, making Invisalign a less-noticeable alternative to metal braces.
The size and shape depends on the type of movement required for that specific tooth. (Below is example of what the actual Invisalign Attachments looks like from one of our patients. As you can see, there are attachments placed and removed without leaving any marks on the teeth). Invisalign Attachments are small shapes of orthodontic composite tooth colored dental material similar to dental fillings that are bonded on teeth during the duration of your treatment. Invisalign Patients can brush, eat and floss like normal with Invisalign Attachments.
