I want to whiten my teeth, but I would rather do it at home and save money - UNLESS spending the big bucks at the dentist is worth it, for some reason - for example, maybe less risk of gum or tooth sensitivity, more effective, or to get significant whitening at home is hours and hours of hassle for not much result. For teeth that are yellow but not stained (no smoking, coffee, wine, etc) do you have experience with home whitening? Did it whiten significantly? Cause problems? Was it ineffective, or not effective enough, so that you ended up doing it at the Dentist anyway? I would love to hear what people's experiences are.
