I just started Invisalign to fix a very minor issue (essentially one crooked lower tooth). My orthodontist is planning 34 sets of trays, which seems too many for such a minor fix. He also is having me wear each set for just a week instead of the two weeks I've read is typical. Not to mention that just 30 hours into wearing them, and I have cuts on my gums, lips, and tongue from the sharp edges. I'm getting suspicious that I'm being taken advantage of. Should I be concerned, or am I overreacting?
