What are common complications, if any, after prosthodontic treatment?

What are the possible complications or side effects that patients may experience after prosthodontic treatment, such as crowns, bridges, dentures, or dental implants, and how common are these issues?

Crowns and bridges can feel weird at first, and gums can be sore. Dentures may rub and need adjustments. Implant failures are rare but can happen. I had a crown placed and just had mild sensitivity that went away in a week or two.
