Risk v benefit: The risk is that the pulp could become uhealthy. The benefit is that the old crowns could be updated with more aesthetic zirconium crowns. Usually trauma is the cause of root fracture.

Replacing crowns: Whether or not to replace PFM crowns with new crowns whether it be another PFM, all metal, or all ceramic crown should really be discussed with a dentist who can discuss this issue on a tooth to tooth basis and whom you trust to help you make that decision. There are a host of factors that need to be taken into account-too many to adequately discuss on this type of forum. There is no simple answer

Not likely: of course, it's always a possibility, but root splitting is not likely, as long as when the crowns are being cut off, they are fully cut through, down to the tooth, before they are removed. Really, unless you have decay on the teeth, there is no need to remove the old crowns. Unless you don't like the look of them or the porcelain has chipped off.
