Teeth aligners are generally less noticeable than traditional braces and can be removed for eating and cleaning. They may be more comfortable to wear, with less irritation to the mouth and treatment time may be shorter for minor tooth movements. On the other hand, traditional braces are typically more effective for complex tooth movements and severe misalignments, require fewer adjustments and may require less discipline to wear consistently, may be covered by insurance more frequently than teeth aligners, and can serve as a visible reminder to keep up with good oral hygiene habits.
