My permanently cemented three-unit bridge in lower jaw, is not functional at all.?

While it was temporary cemented and good fitting, I was capable eating on it, but an extra temporary cement made my gum to reseed, so the dentist had to add an extra ceramic layer at the marginal site to cover the root, but then my bite changed and also, since then I've been experiencing pressure pain on the corrected tooth. It is not because of inflamed pulp, neither it is the gum, so is it possible that the bridge is not fitting properly now and is this correctable now?
