Aligners, also known as invisible braces or clear braces, are a type of orthodontic treatment used to straighten teeth and correct mild to moderate dental misalignments. They are a popular alternative to traditional braces, as they offer a discreet and more aesthetically pleasing way to achieve a straighter smile. Clear aligners or Invisible aligners are custom-made, removable trays made from transparent plastic material. Each aligner is designed to fit closely over the teeth and gradually move them into their desired positions over time. Patients typically receive a series of aligners, and they switch to a new set every few weeks as their teeth progress through the treatment process.
