I'm interested in having my teeth whitened. However, I have an incisor bridge. Only one tooth is involved in the bridge; everything is attached behind the teeth on either side and does not cover the teeth at all. My concern is this: the bridged tooth was matched to the current color of my teeth (off white). I'm thinking that if I go through with the whitening process, this bridged tooth will not change in color. Correct? Is there anyway to whiten the bridged tooth to match the other teeth?

Your bridged tooth will not change color. It is not a real tooth and is probably made out of porcelain or some type of acrylic. Talk with your dentist.
At my office, if a patient wants to cahnge the color of their teeth and they have anterior crown or bridge work, the dentist will do the bleaching for free!
Good luck!
