The 'clear' advantage of Invisalign orthodontic treatment is that the aligners are transparent, making them much more discreet than traditional braces. Invisalign makes it harder for people to tell that you're straightening your smile.
Invisalign orthodontic treatment is a series of clear, removable aligners that are an alternative to traditional metal braces. Invisalign's thin plastic aligners are worn over your teeth to move them into their correct positions.
It can be difficult for others to detect that you're wearing anything on your teeth if you clean and care for your aligners properly.
Whether or not your aligners are visible will depend on how close the person is to you.
It is almost impossible to see the clear aligners from a distance but if someone were to take a very close look at your mouth they might be able to tell that you are wearing them.
So, while Invisalign isn’t completely invisible, the aligners are significantly less noticeable than wires and brackets, giving you a discreet way to straighten your smile.
