Coming from someone with low pain tolerance, I can say that I haven't dealt with any intense pain with the use of Invisalign.

I've read several blogs and comments saying that people need to take pain medication while using Invisalign. So far with my 5th trays, I haven't came across that situation yet. I mean maybe it just depends on your teeth, and how severe the treatment is.

I guess I should begin by telling you a little about my teeth. I have crowding, where 2 teeth overlap a teeny bit onto other teeth. I have crossbite where some of my teeth go in and some go out, and I have an underbite.
