My zirconia bridge is not as bright as I would like. Can this be improved upon?

Hello there,Unfortunately, there is no way to change the shade of your bridge now that it is permanently cemented. Changing the shade would involve your dentist cutting your current bridge off and having a new bridge made. If you opt to do this, be sure that you love the color of your new bridge before it's permanently cemented. Good luck and I hope this helps.

The brightness
of the bridge that you want to improve is really its color. Also,zirconia bridges
have a very opaque core compared to other materials,and that affects the
brightness of your bridge as well. If the bridge is permanently cemented, the
only way to improve it is to get it redone. Talk to your dentist about the
options.

Unfortunately the answer is no. Once a bridge is cemented the only way to change the color is to remove and remake it. Did you look at the bridge in your mouth prior to cementing it? I would share your concerns with your dentist but they are not obligated to remake it. 

The downside to color stability is when you WANT to change color.  This normally means that the entire restoration would need to be remade, so if it was REALLY close, it would not likely be worth the time and effort.
