Is Teeth Whitening Worth It?

I drink 2 cups of coffee a day. I don't smoke, but you can still see the toll that coffee has taken on my teeth when I smile. Some of my friends know how much I hate my teeth and they have tried to get me to buy a toothpaste that whitens teeth. I tried it and I couldn't notice a difference. We all have our insecurities, my smile is definitely one of them. I know that there are several places around town that offer teeth whitening, I am considering talking to my dentist about it when I go in for my teeth cleaning.

I am curious, and since I always seem to come to you for advice, I have to ask you first. Have you ever gotten your teeth whitened? Is the teeth sensitivity pretty bad afterward? I know that teeth sensitivity is one of the most annoying things ever. I am willing to consider anything here, so send me your pros and cons. I have a day to decide if this is something I want to set up an appointment for. Looking forward to hearing back from you in the comments below!
