What is the difference between braces and clear aligners?

A factor would be the aesthetic aspect of it. Some people just refuse to wear something metallic in their mouth. Then you’d have to choose the other option, which is clear aligners. Or there are the ceramic braces as well, ceramic braces is like a good in-between I would say. They function like your metal braces, but they look a bit better because they’re almost tooth-coloured. But of course, it is not as aesthetic compared to clear aligners.
