Invisalign is a popular orthodontic treatment that uses clear, removable aligners to gradually straighten teeth. It serves as an alternative to traditional metal braces. The aligners are custom-made using 3D imaging and are designed to fit snugly over the teeth, exerting gentle pressure to move them into the desired position over time. Invisalign is often used for cases involving mild to moderate misalignments, including crowding, gaps, and bite issues, though severe cases may still require traditional braces or other orthodontic interventions. Regular check-ins with an orthodontist are needed to monitor progress and receive new sets of aligners.
