    Is bacteria, leading to an infection of a pontic, more likely to accumulate under a bridge made of porcelain or one made of PFM?
    I was informed that because a bridge made from porcelain is built by a computer, from a 3D model, it is free of errors in its fit, unlike a PFM bridge, which is made by hand and therefore would not be a perfect fit, and therefore would be more likely to lead to infection and a need for a root canal.

    many things you have covered with this statment but you must be aware that fitting the bridge is one thing and maintain adequate oral health is other. Duration of bridges depends on multiple factors. but I would say that adequate tooth preparation, good restoration either PFM od full ceramics and good oral hygiene are prerogatives for longevity of that bridge.

    Would the cement resin used to attach the bridge to the pontics more likely to deteriorate and lead to an entrance of bacteria in a porcelain or a PFM bridge, or neither, as the cement does not deteriorate?

    we use the same cement during the process...so that one is not so importatnt, but the good oral hygiene is most crucial
