Hey, I'm working in an MNC. My job is very stressful and as a coffee addict, I used to take at least six coffee per day as a stress relief. My dad used to advise me not to take too much coffee which is bad for health. But I cannot control it even if I try it. Yesterday when I posed for the selfies my teeth look yellowish and smiled without showing my teeth. When I talk I tried to cover my teeth because I don't want to show anyone my stained teeth. I discussed with my colleague and she suggested me to get cosmetic dentistry procedure teeth whitening from Edmonton ( http://www.rootsonwhytedental.com/services/cosmetic-dentistry/ ) . But I'm doubtful whether there is any problem of teeth sensitivity after getting treatment. Kindly share your before and after photos of teeth whitening and give your suggestions to recover my smile.
