Going to be in Shenzhen anyway so agreed to go with a friend to get our teeth whitened whilst there (saving pennies) but am now nervous as we both don't know anyone who has had this done over there.
Can anyone recommend a dentist (and how much it cost) - if not then may just get my teeth polished (as they are quite white anyway)
not that I am much help - i really wouldnt if it was me - how would you know they are approved, trained properly etc.. when it comes to your health, is it worth risking?
