How I did it: My dad's a dentist, but otherwise, you just make an appointment, go to the appointment, sit in the chair, let them put the stuff on you, sit there for an hour, then walk away. I didn't have any sensitivity, but they warned me that I might, so I guess it's a possibility.

Resources: A dentist, his teeth-whitening stuff, and a dentist's chair to sit in.
