For invisalign it's 100.00 per tray as in upper and lower, it depends on how many sets you will need to straighten your teeth. You were a set for two weeks but can't eat with them on. The last set for I month. hope this helps.
No 1 can give you a price you need to have a consultation they will tell you !! Because it all depends on your teeth ! My friend only paid $1,200 bc his teeth weren't the bad and my brother in law paid $8,000 ! So it all depends on your teeth
