Clear aligners are orthodontic devices made from transparent plastic to straighten teeth discreetly. Brands like Invisalign and ClearCorrect offer these custom-fitted trays as an alternative to metal braces. Treatment starts with a digital scan of the teeth to create a series of aligners that gradually shift teeth into place. Worn for 20-22 hours daily, they are replaced every one to two weeks. Clear aligners are comfortable and nearly invisible, appealing to those concerned about aesthetics. However, they require strict compliance and may not be suitable for complex cases. Regular check-ups ensure proper progression of the treatment.
