Roughly speaking, it is not possible to correct those cracks in the mouth because the ceramic needs to be melted at a very high temperature which cannot be done in the oral cavity. If your crowns have a warranty certificate with them, they can be replaced for such damages.
The best step would be to get yourself evaluated for the current condition of those Crowns. And the option of replacing the Old Bridge with the new one is always there if the repair work is not possible.
