Am I Suitable for Clear Aligners? Aligners are one of the most advanced orthodontic treatments available today, helping millions of patients each year gain a healthy and beautiful smile. A modern teeth aligner solution may be an ideal solution if you feel mild to moderate alignment issues, such as crowding, gaps, or overbites. The success of treatment depends on your discipline, including wearing the aligners for 20 to 22 hours a day, maintaining excellent oral hygiene, and having healthy teeth as well as gums.
