Root canal: This can be done. It is more challenging than doing it without the crown/bridge on but the cost of cutting the bridge off to do the root canal isuch great than doing the root canal through the abutment tooth on the bridge. You just have to accept the risks of porcelain fracture and loosening of the bridge when it is drilled through...these are risks, but it can be done successfully.

Yes: This is done quite often to save the crown and/or bridge. Risks include a weaker biting surface that can result in flaking or fracture of the porcelain.
