No you are right on. When I got my crown my dentist asked me if I wanted it lighter then my other teeth by a few shades. Since she knew that I was also wanting to whiten my teeth. If I got it the same color as my teeth were then, I would have had one dark tooth after I had whiten the rest of my teeth. So speak to your dentist about getting the right shade for you, since you do want to whiten the rest of your real teeth.
