white teeth. so i go, to get my teeth whitened. simple enough. i want to use my flexible benefits. i go do it. it is by far the most painful experience i have ever had. left in a room with sheer tin crunching shoots of pain through specific teeth. 3 20 minute sessions under the lamp. Peroxide burning through layers of tooth, drying out all dentin. I could barely deal with the remainder of the day... it was like I had undergone major surgery and volts of pain would come back through my teeth to remind of what a stupid manuever of getting my teeth professionally whitened was. Today two teeth are having flash backs. IT IS SO PAINFUL!
