I just got my invisialign this week. Compared to the metal braces I had as a teenager, these are super easy, comfortable, and damn near impossible to see. My only gripe is that it's a pain to pop them in and out just to drink a diet red bull on my way to work in the morning, etc. Aside from being a pain I hate to be seen drooling and reaching into my mouth. So can I get away with an occasional clear sugar free drink or should I just take them out?
