Cutiepie asked:

Which works better and has less side side effects?
Also, which Whitestrips work best? (if you think the Whitestrips are better than going to the dentist)
Thank you!
Thank you for the answers! So has anyone tried the Crest Whitestrips? Which of those work the best? Also, money isn’t too much of a deciding factor for me, I would just like to know which works best, lasts the longest, and has the least after-pain. Thanks again!
