Clear aligners are a series of custom-made, removable trays that gently shift your teeth into position over time. Each set is worn for about 1–2 weeks, for 20–22 hours per day, and gradually moves your teeth based on a digital treatment plan created by your orthodontist.

Benefits include:

  • Nearly invisible appearance
  • Removable for eating and brushing
  • No metal brackets or wires
  • Fewer in-office visits in many cases

Aligners are best for mild to moderate cases, and patient compliance is essential for success.
