Designed for adults and teens, Invisalign® and Invisalign Teen® are clear aligners that are custom-made to your teeth. These clear aligners are made of plastic that is nearly invisible and are replaced regularly to gradually shift teeth into proper position. Patients are typically given 18-30 custom made aligners to use throughout their treatment. Unlike metal and clear braces, there are no metal brackets to attach and no wires to tighten. While the Invisalign option offers the most discreet appearance and freedom to eat and drink foods of your choice, they are not as well suited to treat more severe orthodontic problems.
