Clear aligners are a type of orthodontic treatment used to straighten teeth. They are made from a transparent plastic material and are custom-fitted to each person's mouth. Unlike traditional braces, which use metal brackets and wires, clear aligners are removable and nearly invisible, making them a popular choice for adults and teens who want a discreet option for improving their smile. The treatment involves wearing a series of aligners that gradually shift the teeth into the desired position. Each set of aligners is typically worn for about two weeks before moving on to the next set. Regular check-ups with an orthodontist ensure that the treatment is progressing as planned.
