Are there any potential problems in the longer term for dental implants?

You should be aware, particularly with single tooth implants, that the degree of bone loss and gum reshaping at the time of the previous tooth being lost may mean that the gum level around the implant supported tooth may differ slightly from that around the adjacent natural tooth or teeth. Some alteration of the gum margin (gum recession) may also occur spontaneously around the implant-supported tooth in the period after the restoration.
