Pros: You can take them off to eat and brush. Cons: Everything else was a lie. Originally, it was said that it would take less than a year. 2 1/2 years later I am still dealing with them. I am trying to finish them up, and as usual, I am having to wait a ridiculous amount of time for my retainer - going on 10 weeks. Regular braces would have been easier, quicker, and my front two teeth would have been straighter with regular braces according to my orthodontist.
