Question:
Firsly, I want to say thankyou for replying to my previous post :D
This is probably going to sound quite odd..but I want to whiten my
teeth after I have my jaw surgery, and I would get it professionally
done like I planned..but I want to try just about everything else out
there before I got and pay X $ considering I'll be payin 20,000 for my
sugery. I heard that Ear drops whiten teeth?? I am not sure if its
true.. but is it SAFE?

Answer:
