Invisible aligners are clear, removable dental devices used to straighten teeth. They are custom-made from a flexible plastic material and are designed to gradually shift teeth into the desired position. Unlike traditional braces, they are less noticeable and can be removed for eating, brushing, and flossing. Patients typically wear a series of aligners, changing to a new set every one to two weeks. Each set is slightly different, applying gentle pressure to move the teeth. Orthodontists or dentists create a treatment plan using 3D imaging to ensure the aligners fit properly and effectively achieve the desired results.
